Document Conventions -- -------------------- We have `underlined' text which represents user input with `-' symbols throughout this document to differentiate it from the machine output. 1. Default (GENERIC) Configuration -- ------------------------------- The following table contains a list of all of the devices that are present in the GENERIC kernel. This is the essential part of the operating system that is placed in your root partition during the installation process. A compressed version of the GENERIC kernel is also used on the installation floppy diskette and DOS boot image. The table describes the various parameters used by the driver to communicate with the hardware in your system. There are four parameters in the table, though not all are used by each and every device: Port The starting I/O port used by the device, shown in hexadecimal. IOMem The lowest (or starting) memory address used by the device, also shown in hexadecimal. IRQ The interrupt the device uses to alert the driver to an event, given in decimal. DRQ The DMA (direct memory access) channel the device uses to move data to and from main memory, also given in decimal. If an entry in the table has `n/a' for a value then it means that the parameter in question does not apply to that device. A value of `dyn' means that the correct value should be determined automatically by the kernel when the system boots and that you don't need to worry about it. If an entry is marked with an *, it means that support is currently not available for it but should be back as soon as someone converts the driver to work within the new 4.0 framework.

If the settings do not match, the kernel may be unable to locate or reliably access the devices in your system. 2. Using UserConfig to change FreeBSD kernel settings -- -------------------------------------------------- The FreeBSD kernel on the install floppy contains drivers for every piece of hardware that could conceivably be used to install the rest of the system with. Unfortunately, PC hardware being what it is, some of these devices can be difficult to detect accurately, and for some, the process of detecting another can cause irreversible confusion. To make this process easier, FreeBSD provides UserConfig. With this tool the user can configure and disable device drivers before the kernel is loaded, avoiding potential conflicts, and eliminating the need to reconfigure hardware to suit the default driver settings. Once FreeBSD is installed, it will remember the changes made using UserConfig, so that they only need be made once. It is important to disable drivers that are not relevant to a system in order to minimize the possibility of interference, which can cause problems that are difficult to track down. UserConfig features a command line interface for users with serial consoles or a need to type commands, and a full screen 'visual' interface, which provides point-and-shoot configuration functionality. Here is a sample UserConfig screen shot in 'visual' mode: ---Active Drivers---------------------------10 Conflicts------Dev---IRQ--Port-- Storage : (Collapsed) Network : NE1000,NE2000,3C503,WD/SMC80xx Ethernet adapters CONF ed0 5 0x280 NE1000,NE2000,3C503,WD/SMC80xx Ethernet adapters CONF ed1 5 0x300 Communications : (Collapsed) Input : (Collapsed) Multimedia : ---Inactive Drivers-------------------------------------------Dev-------------- Storage : Network : (Collapsed) Communications : Input : Multimedia : ---Parameters-for-device-ed0--------------------------------------------------- Port address : 0x280 Memory address : 0xd8000 IRQ number : 5 Memory size : 0x2000 Flags : 0x0000 ------------------------------------------------------------------------------- IO Port address (Hexadecimal, 0x1-0x2000) [TAB] Change fields [Q] Save device parameters The screen is divided into four sections : - Active Drivers. Listed here are the device drivers that are currently enabled, and their basic parameters. - Inactive Drivers. These drivers are present, but are disabled. - Parameter edit field. This area is used for editing driver parameters. - Help area. Keystroke help is displayed here. One of the Active and Inactive lists is always in use, and the current entry in the list will be shown with a highlight bar. If there are more entries in a list than can be shown, it will scroll. The bar can be moved up and down using the cursor keys, and moved between lists with the TAB key. Drivers in the Active list may be marked "CONF". This indicates that one or more of their parameters conflicts with another device, and indicates a potential for problems. The total number of conflicts is displayed at the top of the screen. As a general rule, conflicts should be avoided, either by disabling conflicting devices that are not present in the system, or by altering their configuration so that they match the installed hardware. In the list areas, drivers are grouped by their basic function. Groups can be 'Collapsed' to simplify the display (this is the default state for all groups). If a group is collapsed, it will be shown with '(Collapsed)' in the list, as above. To Expand a Collapsed group, position the highlight bar over the group heading and press Enter. To Collapse it again, repeat the process. When a device driver in the Active list is highlighted, its full parameters are displayed in the Parameter edit area. Note that not all drivers use all possible parameters, and some hardware supported by drivers may not use all the parameters the driver supports. To disable a driver, go to the Active list, Expand the group it is in, highlight the driver and press Del. The driver will move to its group in the Inactive list. (If the group is collapsed or off the screen, you may not see the driver in its new location.) To enable a driver, go to the Inactive list, Expand the group it is in, highlight the driver and press Enter. The highlight will move to the Active list, and the driver you have just enabled will be highlighted, ready to be configured. To configure a driver, go to the Active list, Expand the group it is in, highlight the driver and press Enter. The cursor will move to the Parameter edit area, and the device's parameters may be edited. While editing parameters, the TAB and cursor keys can be used to move between fields. Most numeric values (except IRQ) are entered in hexadecimal, as indicated by the '0x' at the beginning of the field. The allowable values for a given field are show in the Key Help area when the field is active. To finish configuring a driver, press 'Q'. Note that PCI, Microchannel and EISA devices can be probed reliably, therefore they are not shown in the table above nor can their settings be changed using UserConfig. 3. LINT - other possible configurations -- ------------------------------------ The following drivers are not in the GENERIC kernel but remain available to those who do not mind compiling a custom kernel (see section 6 of FreeBSD.FAQ). The LINT configuration file (/sys/i386/conf/LINT) also contains prototype entries for just about every device supported by FreeBSD and is a good general reference. The device names and a short description of each are listed below. The port numbers, etc, are not meaningful here since you will need to compile a custom kernel to gain access to these devices anyway and can thus adjust the addresses to match the hardware in your computer in the process. The LINT file contains prototype entries for all of the below which you can easily cut-and-paste into your own file (or simply copy LINT and edit it to taste): ata: Alternate high-performance driver for IDE controllers ctx: Cortex-I frame grabber cx: Cronyx/Sigma multiport sync/async cy: Cyclades high-speed serial driver el: 3Com 3C501 fea: DEC DEFEA EISA FDDI adapter fpa: DEC DEFPA PCI FDDI adapter gp: National Instruments AT-GPIB and AT-GPIB/TNT board gsc: Genius GS-4500 hand scanner gus: Gravis Ultrasound - Ultrasound, Ultrasound 16, Ultrasound MAX gusxvi: Gravis Ultrasound 16-bit PCM hea: Efficient ENI-155p ATM PCI adapter hfa: FORE PCA-200E ATM PCI adapter isic: isdn4bsd Siemens ISDN Chipset driver joy: Joystick labpc: National Instrument's Lab-PC and Lab-PC+ meteor: Matrox Meteor frame-grabber card bktr: Brooktree Bt848 / Bt 878 based frame-grabber cards. mpu: Roland MPU-401 stand-alone card mse: Microsoft, Logitech, ATI bus mouse ports mss: Microsoft Sound System opl: Yamaha OPL-2 and OPL-3 FM - SB, SB Pro, SB 16, ProAudioSpectrum pas: ProAudioSpectrum PCM and MIDI pca: PCM audio ("/dev/audio") through your PC speaker pcm: PCM audio on most modern PCI/ISA audio codecs psm: PS/2 mouse port rc: RISCom/8 multiport card sb: SoundBlaster PCM - SoundBlaster, SB Pro, SB16, ProAudioSpectrum sbmidi: SoundBlaster 16 MIDI interface sbxvi: SoundBlaster 16 si: Specialix SI/XIO/SX (old and enhanced ISA, PCI, EISA) serial sym: Alternate high-performance driver for NCR/LSI Logic SCSI controllers spigot: Creative Labs Video Spigot video-acquisition board uart: Stand-alone 6850 UART for MIDI wds: Western Digital WD7000 IDE --- end of list --- 4.

In particular information on system quirks is more than welcome. Overview -------- This document tries to provide a starting point for those who want to start running FreeBSD on an Alpha-based machine. It is aimed at providing background information on the various hardware designs. It is not a replacement for the systems manuals. The information is structured as follows: - general hardware requirements to run FreeBSD on Alpha. - system specific information for each of the systems/boards supported by FreeBSD/alpha. - information on expansion boards for FreeBSD/alpha, including things that differ from what is in the generic supported hardware list. Note: you will see references to DEC, Digital Equipment Corporation and Compaq used more or less interchangeably. Now that Compaq has acquired Digital Equipment it would be more correct to refer to Compaq-only. In general, what do you need to run FreeBSD/alpha? -------------------------------------------------- Obviously you will need an Alpha machine that FreeBSD/alpha knows about. Alpha machines are NOT like PCs. There are considerable differences between the various chip sets and mainboard designs. This means that a kernel needs to know the intimate details of a particular machine before it can run on it. Throwing some odd GENERIC kernel at unknown hardware is almost guaranteed to fail miserably. For a machine even to be considered for FreeBSD use please make sure it has the SRM console firmware installed. Or at least make sure that SRM console firmware is available for this particular machine type. If FreeBSD does not currently support your machine type, there is a good chance that this will change at some point in time, assuming SRM is available. Machines with the ARC or AlphaBIOS console firmware were intended for WindowsNT. Some of them have SRM firmware available in the system ROMs which you only have to select (via an ARC or AlphaBIOS menu). In other cases you will have to re-flash the ROMs with SRM code. Check on http://ftp.digital.com/pub/DEC/Alpha/firmware to see what is available for your particular system. In any case: no SRM -> no FreeBSD (or NetBSD, OpenBSD, Tru64 Unix or OpenVMS for that matter). With the demise of WindowsNT/alpha a lot of former NT boxes are sold on the second hand market. They have little or no trade-in value when they are NT-only from the console perspective. So, be suspicious if the price appears too good. Known non-SRM machines are: Digital XL series Digital XLT series Samsung PC164UX Samsung 164B To complicate things a bit further: Digital used to have so called 'white-box' Alpha machines destined as NT-only and 'blue-box' Alpha machines destined for OpenVMS and Digital Unix. These names are based on the color of the cabinets, 'FrostWhite' and 'TopGunBlue' respectively. Although you could put the SRM console on the whitebox, OpenVMS and Digital Unix will refuse to boot on them. FreeBSD in post-4.0R will run on both the white and the blue-box variants. Before someone asks: the white ones had a rather different (read: cheaper) price tag. As part of the SRM you will get the so called OSF/1 PAL code (OSF/1 being the initial name of Digital's Unix offering on Alpha). The PAL code can be thought of as a software abstraction layer between the hardware and the operating system. It uses normal CPU instruction plus a handful of privileged instructions specific for PAL use. PAL is not microcode by the way. The ARC firmware contains a different PAL code, geared towards WinNT and in no way suitable for use by FreeBSD (or more generic: Unix or OpenVMS). Before someone asks: Linux/alpha brings its own PAL code, allowing it to boot on ARC & AlphaBIOS. There are various reasons why this is not a very good idea in the eyes of the *BSD folks. I don't want to go into details here. There is another pitfall ahead: you will need a disk adapter that the SRM console recognizes in order to be able to boot from your disk. What is acceptable to SRM as a boot adapter is unfortunately system and SRM version dependent. For older PCI based machines this means you will need either a NCR/Symbios 53C810 based adapter, or a Qlogic 1020/1040 based adapter. Some machines come with a SCSI chip embedded on the mainboard. Newer machine designs and SRM versions will be able to work with later SCSI chips/adapters. Check out the machine specific info below. Please note that the rest of this discussion only refers to Symbios chips, this is meant to include the older chips that still have NCR stamped on them. Symbios bought the NCR designs. The problem might bite those who have machines that started their lives as WinNT boxes. The ARC or AlphaBIOS knows about *other* adapter types that it can boot from than the SRM. For example you can boot from an Adaptec 2940UW with ARC but (generally) not with SRM. Some newer machine types have introduced Adaptec boot support. Please consult the machine specific section for details. Some adapters that cannot be booted from work fine for data-only disks. The differences between SRM and ARC could also get you pre-packaged IDE CDROMs and hard drives in some (former NT) systems. SRM versions exist (depends on the machine type) that can boot from IDE disks and CDROMs. Check the machine specific section for details. FreeBSD/alpha 4.0 and later can be booted from the distribution CDROM. Earlier versions needed booting from a 2-floppy set. If you don't have/want a local disk drive you can boot via the Ethernet. This assumes a Ethernet adapter/chip that is recognized by the SRM. Generally speaking this boils down to either a 21040 or 21142 or 21143 based Ethernet interface. Older machines / SRM versions may not recognize the 21142 / 21143 Fast Ethernet chips, you are limited to using 10Mbit Ethernet for net booting those machines. Non-DEC cards based on said chips will generally (but are not guaranteed to) work. Note that Intel took over the 21x4x chips when it bought Digital Semiconductor. So you might see an Intel logo on them these days. Recent machine designs have SRM support for Intel 8255x Ethernet chips. Alpha machines can be run with SRM on a graphics console or on a serial console. ARC can be run on a serial consoles if need be. VT100 emulation with 8 bit controls should at least allow you to switch from ARC to SRM mode without having to install a graphics card first. If you want to run your Alpha without a monitor/graphics card just don't connect a keyboard/mouse to the machine. Instead hook up a serial terminal[emulator] to serial port #1. The SRM will talk 9600N81 to you. This can be really practical for debugging purposes. Beware: some/most (?) SRMs will also present you with a console prompt at serial port #2. The booting kernel, however, will display the boot messages on serial port #1 and will also put the console there. This can be extremely confusing. Most PCI based Alphas can use ordinary PC-type VGA cards. The SRM contains enough smarts to make that work. It does not, however, mean that each and every PCI VGA card out on the street will work in an Alpha machine. Things like S3 Trio64, Mach64, and Matrox Millennium generally work. Old ET4000 based ISA cards have also worked for me. But ask around first before buying. Please note that TGA cards are not supported as FreeBSD console display cards. Most PCI devices from the PC-world will also work in FreeBSD/alpha PCI-based machines. Check the /sys/alpha/conf/GENERIC file for the latest word on this. Be careful to check the appropriate machine type's discussion in case you want to use PCI cards that have PCI bridge chips on them. In some cases you might encounter problems with PCI cards not handling PCI parity correctly. This can lead to panics. PCI parity checking can be disabled using the following SRM command: SET PCI_PARITY OFF. This is not a FreeBSD problem, all operating systems running on Alpha hardware will need this workaround. If your system (also) contains EISA expansion slots you will need to run the EISA Configuration Utility (ECU) after you have installed EISA cards or have upgraded your console firmware. Parallel ports that can be found on most Alpha machines are supported. For Alpha CPUs you will find multiple generations. The original Alpha design is the 21064. It was produced in a chip process called MOS4, chips made in this process are nicknamed EV4. Newer CPUs are 21164, 21264 etc. You will see designations like EV4S, EV45, EV5, EV56, EV6, EV67. The EVs with double digit numbers are slightly improved versions. For example EV45 has an improved FPU and 16 kByte on-chip separate I & D caches compared to the EV4 on which it is based. Rule of thumb: the higher the digit immediately following 'EV' the more desirable (read: faster / more modern). For memory you want at least 32 Mbytes. I have had FreeBSD/alpha run on a 16 Mbyte system but you will not like that. Kernel build times halved when going to 32 Mbytes. Note that the SRM steals 2Mbyte from the total system memory (and keeps it). For more serious use >= 64Mbyte is recommended. While on the subject of memory: pay close attention to the type of memory your machine uses. There are very different memory configurations and requirements for the various machines. Final word: I expect the above to sound a bit daunting to the first-time Alpha user. Don't be daunted too much. And do feel free to ask questions. System specific information --------------------------- Below is an overview of the hardware that FreeBSD/alpha runs on. This list will definitely grow, a look in /sys/alpha/conf/GENERIC can be enlightening. Alpha machines are often best known by their project code name. When known these are listed below in (). * * AXPpci33 ("NoName") * The NoName is a baby-AT mainboard based on the 21066 LCA (Low Cost Alpha) processor. It was originally designed for OEM-use. The LCA chip includes almost all of the logic to drive a PCI bus and the memory subsystem. All of this makes for a low-priced design. Due to the limited memory interface the system is not particularly fast in case of cache misses. As long as you stay inside the on-chip cache the CPU is comparable to a 21064 (first generation Alpha). These boards should be very cheap to obtain these days (even here in the Netherlands they were sold new for US$ 25). Features: - 21066 Alpha CPU at 166 MHz or 21066A CPU at 233MHz (21068 CPUs are also possible, but are even slower. Never seen/used one) - memory bus: 64 bits - on-board Bcache / L2 cache: 0, 256k or 1 Mbyte (uses DIL chips) - PS/2 mouse & keyboard port OR 5pin DIN keyboard (2 mainboard models) - memory: PS/2 style 72 pin 36 bit Fast Page Mode SIMMs, 70ns or better, installed in pairs of 2, 4 SIMM sockets uses ECC - 512kB Flash ROM for the console code. - 2x 16550A serial ports, 1x parallel port, floppy interface - 1x embedded IDE interface - expansion: 3 32 bit PCI slots (1 shared with ISA) 5 ISA slots (1 shared with PCI) - embedded Fast SCSI using a Symbios 53C810 chip SRM: NoNames can either have SRM *or* ARC console firmware in their Flash ROM. The Flash ROM is not big enough to hold both ARC and SRM at the same time and allow software selection of alternate console code. But you need SRM-only anyway. Cache: Cache for the NoNames are 15 or 20 ns DIL chips. For a 256 kByte cache you want to check your junked 486 mainboard. Chips for a 1 Mbyte cache are a rarer breed unfortunately. Getting at least a 256kByte cache is recommended performance wise. Cache-less they are really slow. Power: The NoName mainboard has a PC/AT-standard power connector. It also has a power connector for 3.3 Volts. No need to rush out to get a new power supply. The 3.3 Volts is only needed in case you run 3.3 Volts PCI expansion boards. IDE: The IDE interface is supported by FreeBSD and requires a line in the kernel configuration file as follows: device ata0 at isa? port IO_WD1 irq 14 The SRM console unfortunately cannot boot from IDE disks. Memory: Make sure you use true 36 bit SIMMs, and only FPM (Fast Page Mode). EDO RAM or SIMMs with fake parity *will not work* (the board uses the 4 extra bits for ECC!). 33 bit FPM SIMMs will for the same reason not work either. Keyboard/mouse: Given the choice, get the PS/2-variant mainboard. Apart from giving you a mouse port as bonus it is directly supported by Tru64 Unix in case you ever want/need to run it. The "DIN-plug"-variant should work OK for FreeBSD. The OEM manual is recommended reading. See ftp://ftp.digital.com/pub/DEC/axppci/design_guide.ps The kernel configuration file for a NoName kernel must contain: options DEC_AXPPCI_33 cpu EV4 * * Universal Desktop Box (UDB or "Multia") * Note: Multia can be either Intel or Alpha CPU based. We assume Alpha based ones here for obvious reasons. Multia is a small desktop box intended as a sort of personal workstation. They come in a considerable number of variations, check closely what you get. Features: - 21066 Alpha CPU at 166 MHz or 21066A CPU at 233MHz - memory bus: 64 bits - on-board Bcache / L2 cache: COAST-like 256 kByte cache module 233MHz models have 512kByte of cache 166MHz models have soldered-on 256kB caches - PS/2 mouse & keyboard port - memory: PS/2 style 72 pin 36 bit Fast Page Mode SIMMs, 70ns or better, installed in pairs of 2, 4 SIMM sockets uses ECC - 2x 16550A serial ports, 1x parallel port, floppy interface - Intel 82378ZB PCI to ISA bridge - 1x embedded 21040 based 10Mbit Ethernet, AUI or 10base2 connector - expansion: 1 32 bit PCI slot, 2 PCMCIA slots - on-board Crystal CS4231 or AD1848 sound chip - embedded Fast SCSI using a Symbios 53C810 chip on the PCI riser card SRM/ARC: Multia has enough Flash ROM to store both SRM and ARC code at the same time and allow software selection of one of them. Expansion: Multia has only one 32 bit PCI slot for expansion, and it is only suitable for a small form factor PCI card too. In sacrificing the PCI slot space you can mount a 3.5" hard disk drive. Mounting stuff may have come with your Multia. Adding a 3.5" disk is not a recommended upgrade due to the limited power rating of the power supply and the extremely marginal cooling of the system box. Don't! Multia also has 2 PCMCIA expansion slots. These are currently unsupported. CPU: The CPU might or might not be socketed, check before considering CPU upgrade hacks. The low-end Multias have a soldered-in CPU. Graphics: It comes with a TGA based graphics on-board. Which is not suitable for console use with FreeBSD. Which means you will have to run it using a serial console. Note that the boot of the installation disk will appear to work fine using the TGA console, but then switches to using the serial port. This is even mentioned during by installer (but never read by the human doing the install..). Your keyboard appears dead from that point on. Serial: Multia has 2 serial ports but routes both of them to the outside world on a single 25 pin sub-D connector. The Multia FAQ explains how to build your own Y-cable to allow both ports to be used. Floppy: Although the Multia SRM supports booting from floppy this is problematic. Typical errors look like "*** Soft Error - Error #10 - FDC: Data overrun or underrun". This is not a FreeBSD problem, it is a SRM problem. The best available workaround to install FreeBSD is to boot from a SCSI CDROM. Sound: Works fine using pcm driver and a line in the kernel configuration file as follows for the Crystal CS4231 chip: device pcm0 at isa? port 0x530 irq 9 drq 3 flags 0x15 I have not yet been successful in getting my Multia with the AD1848 to play any sound. While verifying playback I was reminded of the lack of CPU power of the 166MHz CPU: MP3 only plays acceptable using 22kHz down-sampling. Hot: Multias are somewhat notorious for dying of heat strokes. The very compact box does not really allow cooling air access very well. Please use the Multia on its vertical stand, don't put it horizontally ('pizza style'). Replacing the fan with something which pushes around more air is recommended. Beware of PCI cards with high power consumption. If your system has died you might want to check on the Multia-Heat-Death pages at the NetBSD web-site http://www.netbsd.org IDE: The Intel 82378ZB PCI to ISA bridge enables the use of an IDE disk. This requires a line in the kernel configuration file as follows: device ata0 at isa? port IO_WD1 irq 14 The IDE connector pin spacing is thought for 2.5" laptop disks. A 3.5" IDE disk would not fit in the case anyway. At least not without sacrificing your only PCI slot. The SRM console does not know how to boot from IDE disks unfortunately. SCSI: In case you want to change the internal hard drive: the internal flat cable running from the PCI riser board to the 2.5" (!!) hard drive has a finer pitch than the standard SCSI flat cables. Otherwise it would not fit on the 2.5" drives. There are also riser cards that have a standard-pitch SCSI cable attached to it, which will fit an ordinary SCSI disk. Again, I recommend against trying to cram a replacement hard disk inside. Use the external SCSI connector and put your disk in an external enclosure. Multias run hot enough as-is. In most cases you will have the external high density 50pin SCSI connector but some Multia models came without disk and may lack the connector. Something to check before buying one. The kernel configuration file for a Multia kernel must contain: options DEC_AXPPCI_33 cpu EV4 More info: Recommended reading on Multia can be found at http://www.netbsd.org/Ports/alpha/multiafaq.html http://www.brouhaha.com/~eric/computers/udb.html * * Personal Workstation ("Miata") * The Miata is a small tower machine intended to be put under a desk. There are multiple Miata variants. The original Miata is the MX5 model. Because it suffers from a number of hardware design flaws a redesign was performed, yielding the MiataGL. Unfortunately the boxes are quite indistinguishable. An easy check is to see if the back of the machine sports two USB connectors. If yes, it is a MiataGL. System designations look like "Personal Workstation 433a". Personal Workstation, being a bit of a mouthful, is often abbreviated to PWS. This means it has a 433 MHz CPU, and started life as a WinNT workstation (the trailing 'a'). Systems designated from day 1 to run Tru64 Unix or OpenVMS will sport '433au'. WinNT-Miatas are likely to come pre-configured with an IDE CDROM drive. So, in general systems are named like PWS[433,500,600]a[u]. There was also a Miata model with a special CPU cooling system by Kryotech. That one has a different enclosure. Features: - 21164A EV56 Alpha CPU, at 433, 500 or 600MHz - 21174 Core Logic ("Pyxis") chip set - on-board Bcache / L3 cache: 0, 2 or 4 Mbytes (uses a cache module) - memory bus: 128 bits wide, ECC protected - memory: Miata uses unbuffered SDRAMs, installed in pairs of 2, 6 DIMM sockets 1.5 Gbytes max - on-board Fast Ethernet based on: - MX5 uses a 21142 or 21143 Ethernet chip dependent on the version of the PCI riser card - MiataGL has a 21143 chip - the bulkhead can be 10/100 UTP, or 10 UTP/BNC - 2x on-board [E]IDE based on: - MX5: CMD646 - MiataGL: Cypress 82C693 - 1x Ultra-Wide SCSI Qlogic 1040 [MiataGL only] - expansion: 2 64-bit PCI slots 3 32-bit PCI slots (behind a DEC PCI-PCI bridge chip) 3 ISA slots (physically shared with the 32 bit PCI slots, via an Intel 82378IB PCI to ISA bridge chip) - 2x 16550A serial port - 1x parallel port - PS/2 keyboard & mouse port - USB interface [MiataGL only] - embedded sound based on an ESS1888 chip CPU mainboard and PCI 'riser' board: The Miata logic is divided into two printed circuit boards. The lower board in the bottom of the machine has the PCI and ISA slots and things like the sound chip etc. The top board has the CPU, the Pyxis chip, memory etc. Note that MX5 and the MiataGL use a different PCI riser board. This means that you cannot just upgrade to a MiataGL CPU board (with the newer Pyxis chip) but that you will also need a different riser board. Apparently an MX5 riser with a MiataGL CPU board will work but it is definitely not a supported or tested configuration. Everything else (cabinet, wiring etc etc) is identical for MX5 and MiataGL. DMA bug: MX5 has problems with DMA via the 2 64-bit PCI slots when this DMA crosses a page boundary. The 32 bit slots don't have this problem because the PCI-PCI bridge chip does not allow the offending transfers. The SRM code knows about the problem and refuses to start the system if there is a PCI card in one of the 64bit slots that it does not know about. Cards that are 'known good' to the SRM are allowed to be used in the 64bit slots. If you want to fool the SRM you can type "set pci_device_override" at the SRM prompt. Just don't complain if your data mysteriously gets mangled. The complete command is: set pci_device_override e.g. set pci_device_override 88c15333 A more radical approach is to use: set pci_device_override -1 This disables PCI ID checking altogether, so that you can stick in any random PCI card without its ID getting checked. For this to work you need a sufficiently new SRM in your Miata. Again: do this on your own risk. The kernel reports it when it sees a buggy Pyxis chip: Sep 16 18:39:43 miata /kernel: cia0: Pyxis, pass 1 Sep 16 18:39:43 miata /kernel: cia0: extended capabilities: 1 Sep 16 18:39:43 miata /kernel: cia0: WARNING: Pyxis pass 1 DMA bug; no bets... A MiataGL probes as: Jan 3 12:22:32 miata /kernel: cia0: Pyxis, pass 1 Jan 3 12:22:32 miata /kernel: cia0: extended capabilities: 1 Jan 3 12:22:32 miata /kernel: pcib0: <2117x PCI host bus adapter> on cia0 MiataGL does not have the DMA problems of the MX5. PCI cards that make the MX5 SRM choke when installed in the 64bit slots are accepted without problems by the MiataGL SRM. The latest mainboard revisions of MX5 contain a hardware workaround for the bug. The SRM does not know about the ECO and will complain about unknown cards as before. So does the FreeBSD kernel by the way. EIDE: The Miata SRM can boot from IDE CDROM drives. Hard disk boot is known to work for both MiataGL and MX5 disks, so you can root FreeBSD from an IDE disk. Speeds on MX5 are around 14 Mbytes/sec assuming a suitable drive. The CMD646 chip will support up to WDMA2 mode as the silicon is too buggy for use with UDMA. PCI-PCI bridge: The MiataGL has a faster PCI-PCI bridge chip on the PCI riser card than some of the MX5 riser card versions. Some of the MX5 risers have the *same* chip as the MiataGL. All in all there is a lot of variation. Not all VGA cards will work behind the PCI-PCI bridge. This manifests itself as no video at all. Workaround is to put the VGA card 'before' the bridge, in one of the 64 bit PCI slots. Sound: Both MX5 and MiataGL have an on-board sound chip, an ESS1888. It emulates a SoundBlaster and can be enabled by putting device pcm0 device sbc0 in your kernel configuration file. Cache: in case your Miata has the optional cache board installed make sure it is firmly seated. A slightly loose cache has been observed to cause weird crashes (not surprising obviously, but maybe not so obvious when troubleshooting). The cache module is identical between MX5 and MiataGL. Installing a 2Mb cache module achieves, apart from a 10-15% speed increase (based on buildworld elapsed time), a *decrease* for PCI DMA read bandwidth from 64bit PCI cards. A benchmark on a 64-bit Myrinet card resulted in a decrease from 149 Mbytes/sec to 115 Mbytes/sec. Something to keep in mind when doing really high speed things with 64 bit PCI adapters. Keyboard: If you experience SRM errors like "ERROR: scancode 0xa3 not supported on PCXAL" after halting FreeBSD you should update your SRM firmware to V7.2-1 or later. This SRM version is first available on the Firmware Update CD V5.7, or on http://www.compaq.com The problem is fixed on both Miata MX5 and Miata GL. USB: Supported by FreeBSD 4.1 and later. Power: Disconnect the power cord before dismantling the machine, the soft-power switch keeps part of the logic powered even when the machine is switched off. The kernel configuration file for a Miata kernel must contain: options DEC_ST550 cpu EV5 * * DEC3000 family (the "Bird" machines) * The DEC3000 series were among the first Alpha machines ever produced. They are based on an I/O bus called the Turbo Channel (TC) bus. These machines are built like tanks (watch your back). DEC3000 can be subdivided in DEC3000/500-class and DEC3000/300-class. The DEC3000/500-class is the early high-end workstation/server Alpha family. Servers use serial consoles, workstations have graphics tubes. DEC3000/300-class is the lower-cost workstation class. DEC3000/500-class are quite fast (considering their age) thanks to the good memory design. DEC3000/300 is crippled compared to DEC3000/500 because of its much narrower memory bus. They are called 'Birds' because their internal DEC code names were bird names: DEC3000/400 Sandpiper 133MHz CPU, desktop DEC3000/500 Flamingo 150MHz CPU, floor standing DEC3000/500X Hot Pink 200MHz CPU, floor standing DEC3000/600 Sandpiper+ 175MHz CPU, desktop DEC3000/700, Sandpiper45 225MHz CPU, floor standing DEC3000/800, Flamingo Ultra 200MHz CPU, floor standing DEC3000/900, Flamingo45 275MHz CPU, floor standing DEC3000/300 Pelican 150MHz CPU, desktop, 2 TC slots DEC3000/300X Pelican+ 175MHz CPU, desktop, 2 TC slots DEC3000/300LX Pelican+ 125MHz CPU, desktop, 2 TC slots DEC3000/300L 100MHz CPU, desktop, no TC slots Features: - 21064 CPU (100 to 200 MHz) 21064A CPU (225 to 275 MHz) - memory bus: 256 bit, with ECC [DEC3000/500-class] 64 bit, with ECC [DEC3000/300-class] - memory: - proprietary 100pin SIMMs installed in sets of 8 [DEC3000/500-class] - PS/2 style 72pin 36 bit FPM SIMMs, 70ns or better used in pairs of 2 [DEC3000/300-class] - Bcache / L2 cache: varying sizes, 512 kB to 2 Mbyte - built-in 10Mbit Ethernet based on a Lance 7990 chip, AUI and UTP - one or two SCSI buses based on a NCR53C94 or a NCR53CF94-2 chip - 2 serial ports based on Zilog 8530 (one usable as a serial console) - embedded ISDN interface - on-board 8 bit sound - 8 bit graphics on-board [some models] or via a TC card [some other models] SCSI: Currently DEC3000 machines can only be used diskless on FreeBSD/alpha. The reason for this is that the SCSI drivers needed for the TC SCSI adapters were not brought into CAM that the recent FreeBSD versions use. TC option cards for single (PMAZ-A) or dual fast SCSI (PMAZC-AA) are also available. And currently have no drivers on FreeBSD either. DEC3000/300 has 5Mbytes/sec SCSI on-board. This bus is used for both internal and external devices. DEC3000/500 has 2 SCSI buses. One is for internal devices only, the other one is for external devices only. Floppy devices found in the DEC3000s are attached to the SCSI bus (via a bridge card). This makes it possible to boot from them using the same device names as ordinary SCSI hard-disks (>>> BOOT DKA300 for example). Expansion: The 3000/300 series has a half-speed TurboChannel compared to the other 3000 machines. Some TC expansion cards have troubles with the half-speed bus. Caveat emptor. ISDN interface: ISDN does not work on FreeBSD. Memory: DEC3000/300-class uses standard 36 bit, 72 pin Fast Page Mode SIMMs. EDO SIMMs, 32 or 33 bit SIMMs all will not work in Pelicans. For 32Mbyte SIMMs to work on the DEC3000/300-class the presence detect bits/pins of the SIMM must correspond to what the machine expects. If they don't, the SIMM is 'seen' as a 8 Mbyte SIMM. 8 Mbyte and 32 Mbyte SIMMs can be mixed, as long as the pairs themselves are identical. When you find yourself in need of fixing 32Mbyte SIMMs that lack correct presence bits the following info might be of use: There are four presence detection bits on PS/2 SIMMs. Two of the bits indicate the access time. The other two indicate the memory size. At one end of the SIMM there are two rows of four solder pads. One row is connected to Vss (GND) and the other is connected to pins 67 (PRD1), 68 (PRD2), 69 (PRD3), 70 (PRD4). If you bridge a pair of pads with a small resistor or a drop of solder you ground that particular bit. PRD1 PRD2 mem. size ----------------------------- GND GND 4 or 64 Mbyte Open GND 2 or 32 Mbyte GND Open 1 or 16 Mbyte Open Open 8 Mbyte PRD3 PRD4 access time ------------------------------ GND GND 50 or 100 nsec Open GND 80 nsec GND Open 70 nsec Open Open 60 nsec DEC3000/500-class can use 2, 4, 8, 16 and 32 Mbyte 100pin SIMMs. Note that the maximum memory size varies from system to system, desktop machines have sacrificed box size for less memory SIMM sockets. Given enough sockets and enough SIMMs you can get to 512 Mbytes maximum. This is one of the main differences between floor standing and desktop machines, the latter have far less SIMM sockets. Sound: The sound hardware is not supported on any of the Birds. Graphics: The is no X-Windows version available for the TC machines. DEC3000/300 needs a serial console. DEC3000/500-class might work with a graphical console. I ran mine with a serial console so I cannot verify this. Birds can be obtained from surplus sales etc. As they are not PCI based they are no longer actively maintained. TC expansion boards can be difficult to obtain these days and support for them is not too good unless you write/debug the code yourself. Programming information for TC boards is hard to find. Birds are recommended only if a. you can get them cheap and b. if you prepared to work on the code to support them better. For the DEC3000/[4-9]00 series machines the kernel config file must contain: options DEC_3000_500 cpu EV4 For the DEC3000/300 ("Pelican") machines the kernel config file must contain: options DEC_3000_300 cpu EV4 * *Evaluation Board 64plus ("EB64+"), Aspen Alpine * In its attempts to popularize the Alpha CPU DEC produced a number of so called Evaluation Boards. The EB64+ family boards have the following feature set: - 21064 or 21064A CPU, 150 to 275MHz - memory bus: 128 bit - memory: PS/2 style 72 pin 33 bit Fast Page Mode SIMMs, 70ns or better, installed in sets of 4 8 SIMM sockets uses parity - Bcache / L2 cache: 512 kByte, 1 Mbyte or 2 Mbytes - 21072 ("APECS") chip set - Intel 82378ZB PCI to ISA bridge chip ('Saturn') - dual 16550A serial ports - Symbios 53C810 Fast-SCSI - embedded 10 Mbit Ethernet - 2 PCI slots - 3 ISA slots Aspen Alpine: Aspen Alpine is slightly different, but is close enough to the EB64+ to run an EB64+ SRM EPROM (mine did..). The Aspen Alpine does not have an embedded Ethernet, has 3 instead of 2 PCI slots. It comes with 2 Mbytes of cache already soldered onto the mainboard. It has jumpers to select the use of 60, 70 or 80ns SIMM speeds. Memory: 36 bits SIMMs work fine, 3 bits simply remain unused. SRM: The SRM console code is housed in an UV-erasable EPROM. No easy flash SRM upgrades for the EB64+ The latest SRM version available for EB64+ is quite ancient anyway. SCSI: The EB64+ SRM can boot both 53C810 and Qlogic1040 SCSI adapters. Pitfall for the Qlogic is that the firmware that is down-loaded by the SRM onto the Qlogic chip is very old. There are no updates for the EB64+ SRM available. So you are stuck with old Qlogic bits too. I have had quite some problems when I wanted to use Ultra-SCSI drives on the Alpine with Qlogic. The FreeBSD/alpha kernel can be compiled to include a much newer Qlogic firmware revision. This is not the default because it adds hundreds of kBytes worth of bloat to the kernel. In FreeBSD 4.1 and later the isp firmware is contained in a kernel loadable module. All of this might mean that you need to use a non-Qlogic adapter to boot from. For the EB64+ class machines the kernel config file must contain: options DEC_EB64PLUS cpu EV4 * * Evaluation Board 164 ("EB164, PC164, PC164LX, PC164SX") family * EB164 is a newer design evaluation board, based on the 21164A CPU. This design has been used to 'spin off' multiple variations, some of which are used by OEM manufacturers/assembly shops. Samsung did its own PC164LX which has only 32 bit PCI, whereas the Digital variant has 64 bit PCI. Features: - 21164A, multiple speed variants [EB164, PC164, PC164LX] 21164PC [only on PC164SX] - 21174 (Alcor) chip set - Bcache / L3 cache: EB164 uses special cache-SIMMs - memory bus: 128 bit / 256 bit - memory: PS/2 style SIMMs in sets of 4 or 8, 36 bit, Fast Page Mode, uses ECC, [EB164 and PC164] SDRAM DIMMs in sets of 2, uses ECC [PC164SX and PC164LX] - dual 16550A serial ports - PS/2 style keyboard & mouse - floppy controller - parallel port - 32 bits PCI - 64 bits PCI [some models] - ISA slots via an Intel 82378ZB PCI to ISA bridge chip Memory: Using 8 SIMMs for a 256bit wide memory can yield interesting speedups over a 4 SIMM/128bit wide memory. Obviously all 8 SIMMs must be of the same type to make this work. The system must be explicitly setup to use the 8 SIMM memory arrangement. You must have 8 SIMMs, 4 SIMMs distributed over 2 banks does not work. SCSI: The SRM can boot from Qlogic 10xx boards or the Symbios 53C810[A]. Newer Symbios 810 revisions like the Symbios 810AE are not recognized by the SRM on PC164. PC164 SRM does not appear to recognize a Symbios 53C895 based host adapter (tested with a Tekram DC-390U2W). On the other hand some no-name Symbios 53C985 board has been reported to work. Cards like the Tekram DC-390F (Symbios875 based) have been confirmed to work fine on the PC164. Unfortunately this seems to be dependent on the actual version of the chip/board. Symbios 53C825[a] will also work as boot adapter. Diamond FirePort, although based on Symbios chips, is not bootable by the PC164SX SRM. PC164SX is reported to boot fine with Symbios825, Symbios875 and Symbios876 based cards. In addition, Adaptec 2940U and 2940UW are reported to work for booting (verified on SRM V5.7-1). Adaptec 2930U2 and 2940U2[W] do not work. LX and SX with SRM firmware version 5.8 or later can boot from Adaptec 2940-series adapters. In summary: this family of machines is 'blessed' with a challenging compatibility as far as SCSI adapters go. SRM quirks: PC164 the SRM sometimes seems to loose its variable settings. "For PC164, current superstition says that, to avoid losing settings, you want to first downgrade to SRM 4.x and then upgrade to a 5.x" One sample error that was observed was: "ERROR: ISA table corrupt!". A sequence of a downgrade to SRM4.9, an 'isacfg -init' and an 'init' made the problem go away. Some PC164 owners report they have never seen the problem. On PC164SX the AlphaBIOS allows you a selection to select 'SRM' to be used as console on the next power up. This selection does not appear to have any effect. In other words, you will get to the AlphaBIOS regardless of what you select. The fix is to reflash the console ROM with the SRM code for PC164SX. This will overwrite the AlphaBIOS and will get you the SRM console you desire. The SRM code can be found on the Compaq Web site. IDE: PC164 can boot from IDE disks assuming your SRM version is recent enough. Power: EB164 needs a power supply that supplies 3.3 Volts. PC164 does not implement the PS_ON signal that ATX power supplies need to switch on. A simple switch pulling this signal to ground fixes this problem. For the EB164 class machines the kernel config file must contain: options DEC_EB164 cpu EV5 * * AlphaStation 200 ("Mustang") and 400 ("Avanti") series * The Digital AlphaStation 200 and 400 series systems are early PCI based workstations for the lower end. The 200 and 250 series is a desktop box, the 400 series is a desk-side mini-tower. Features: - 21064 or 21064A CPU at speeds of 166 to 333 MHz - DECchip 21071-AA (core logic chip-set) consisting of: Cache/memory controller (one 21071-CA chip) PCI interface (one 21071-DA chip) Data path (two 21071-BA chips) - Bcache / L2 cache: 512 Kbytes (200 and 400 series) 2048KBytes (250 series) - memory bus: 64 bit - memory: 8 to 384 MBytes of RAM, 70 ns or better Fast Page DRAM, in three pairs (200 and 400 series) in two quads, so banks of four. (250 series) uses parity - PS/2 keyboard and mouse port - two 16550 serial ports - parallel port - floppy disk interface - 32 bit PCI expansion slots (3 for 400 series, 2 for 200 & 250 series) - ISA expansion slots (4 for 400 series, 2 for 200 & 250 series) (some ISA/PCI slots are physically shared) - embedded 21040-based Ethernet (200 & 250 series) - embedded Symbios 53c810 Fast SCSI-2 chip - Intel 82378IB ("Saturn") PCI-ISA bridge chip - graphics is embedded TGA or PCI VGA (model dependent) - 16 bit sound (on 200 & 250 series) Memory: the system uses parity memory SIMMs, but it does not need 36 bit wide SIMMs. 33 bit wide SIMMs are sufficient, 36 bit SIMMs are acceptable too. EDO or 32 bit SIMMs will not work. 4, 8, 16, 32 and 64 Mbyte SIMMs are supported. Sound: The AS200 & AS250 sound hardware is reported to work OK assuming you have the following line in your kernel config file: device pcm0 at isa? port 0x530 irq 9 drq 0 flags 0x10011 SCSI: AlphaStation 200 & 250 series has an automatic SCSI terminator. This means that as soon as you plug a cable onto the external SCSI connector the internal terminator of the system is disabled. It also means that you should not leave unterminated cables plugged into the machine. AlphaStation 400 series have an SRM variable that controls termination. In case you have external SCSI devices connected you must set this SRM variable using: "set control_scsi_term external". If only internal SCSI devices are present use: "set control_scsi_term internal" For the AlphaStation-[24][05]00 machines the kernel config file must contain: options DEC_2100_A50 cpu EV4 * * AlphaStation 500 and 600 ("Alcor" & "Maverick" for EV5, "Bret" for EV56) * AS500 and 600 were the high-end EV5 / PCI based workstations. EV6 based machines have in the meantime taken their place as front runners. AS500 is a desktop in a dark blue case (TopGun blue), AS600 is a sturdy desk-side box. AS600 has a nice LCD panel to observe the early stages of SRM startup. Features: - 21164 EV5 CPU at 266, 300, 333, 366, 400, 433, 466, or 500 MHz (AS500) at 266, 300 or 333 MHz (AS600) - 21171 or 21172 (Alcor) core logic chip-set - cache: 2 or 4 Mb L3 / Bcache (AS600 at 266 MHz) 4 Mb L3 / Bcache (AS600 at 300 MHz) 2 or 8 Mb L3 / Bcache (8 Mb on 500 MHz version only) 2 to 16 Mb L3 / Bcache (AS600; 3 cache-SIMM slots) - memory bus: 256 bits, uses ECC - memory: AS500: industry standard 8 byte wide DIMMs 8 DIMM slots installed in sets of 4, maximum memory is 1 Gb (512 Mb max on 333 MHz CPUs) uses ECC AS600: industry standard 36 bit Fast Page Mode SIMMs 32 SIMM slots, installed in sets of 8, maximum memory is 1 Gb uses ECC - Qlogic 1020 based wide SCSI bus (1 bus/chip for AS500, 2 for AS600) - 21040 based 10 Mbit Ethernet adapter with both Thinwire and UTP connectors - expansion: AS500: 3 32-bit PCI slots 1 64-bit PCI slot AS600: 2 32-bit PCI slot 3 64-bit PCI slots 1 PCI/EISA physically shared slot 3 EISA slots 1 PCI and 1 EISA slot are occupied by default - 21050 PCI-to-PCI bridge chip - Intel 82375EB PCI-EISA bridge (AS600 only) - 2 16550A serial ports - 1 parallel port - 16 bit audio Windows Sound System, in dedicated slot (AS500) in EISA slot (AS600, this is an ISA card) - PS/2 keyboard and mouse port SCSI: Early machines had Fast SCSI interfaces, later ones are Ultra SCSI capable. AS500 shares its single SCSI bus with internal and external devices. For a Fast SCSI bus you are limited to 1.8 meters bus length external to the box. +++ This is what some DEC docs suggest. Did they ever go Ultra? AS600 has one Qlogic chip dedicated to the internal devices whereas the other one is dedicated to external SCSI devices. Memory: In AS500 DIMMs are installed in sets of 4, in 'physically interleaved' layout. So, a bank of 4 DIMMs is *not* 4 adjacent DIMMs! In AS600 the memory SIMMs are placed onto two memory daughter cards. SIMMs are installed in sets of 8. Both memory daughter cards must be populated identical. PCI: AS600 has a peculiarity for its PCI slots. AS600 (or rather the PCI expansion card containing the SCSI adapters) does not allow I/O port mapping, therefore all devices behind it must use memory mapping. If you have problems getting the SCSI adapters to work, add the following option to /boot/loader.rc: set isp_mem_map=0xff This may need to be typed at the boot loader prompt before booting the installation kernel. For the AlphaStation-[56]00 machines the kernel config file must contain: options DEC_KN20AA cpu EV5 * * AlphaServer 1000 ("Mikasa"), 1000A ("Noritake") and 800 * The AlphaServer 1000 and 800 range of machines is aimed as departmental servers. They come in quite some variations in packaging and mainboard/cpu. Generally speaking there are 21064 (EV4) CPU based machines and 21164 (EV5) based ones. The CPU is on a daughter card, and the type of CPU (EV4 or EV5) must match the mainboard in use. AlphaServer 800 is a much smaller mini tower case, it lacks the StorageWorks SCSI hot-plug chassis. The main difference between AS1000 and AS1000A is that AS1000A has 7 PCI slots whereas AS1000 only has 3 PCI slots and has EISA slots instead. AS800 with an EV5/400 MHz CPU was later re-branded as a DIGITAL Server 3300[R], AS800 with an EV5/500 MHz CPU was later re-branded as a DIGITAL Server 3305[R]. Features: - 21064 EV4[5] CPU at 200, 233 or 266 MHz 21164 EV5[6] CPU at 300, 333 or 400 MHz (or 500 MHz for AS800 only) - cache: - memory bus: 128 bit with ECC - memory: AS1000[A]-systems: Use 72pin 36 bit Fast Page Mode SIMMs, 70ns or better 16 or 20 SIMM slots max memory is 1 Gb uses ECC AS800: Uses SDRAM DIMMs. - embedded VGA (on some mainboard models) - expansion: 3 PCI, 2 EISA, 1 64-bit PCI/EISA combo (AS800) 7 PCI, 2 EISA (AS1000A) 2 PCI, 1 EISA/PCI, 7 EISA (AS1000) - embedded SCSI based on Symbios 810 [AS1000] or Qlogic 1020 [AS1000A] Box: AS1000 based machines come in multiple boxes. Floor standing, rack-mount, with or without StorageWorks SCSI chassis etc. The electronics are the same. Memory: AS1000-systems: All EV4 based machines use standard PS/2 style 36 bit 72pin SIMMs in sets of 5. The fifth SIMM is used for ECC. All EV5 based machines use standard PS/2 style 36 bit 72pin SIMMs in sets of 4. The ECC is done based on the 4 extra bits per SIMM (4 bits out of 36). The EV5 mainboards have 16 SIMM slots, the EV4 mainboards have 20 slots. AS800: Uses DIMMs in sets of 4. DIMM installation must start in slots marked bank 0. A bank is four physically adjacent slots. The biggest size DIMMs must be installed in bank 0 in case 2 banks of different DIMM sizes are used. Max memory size is 2Gb. Console: The AS1000/800 are somewhat stubborn when it comes to serial consoles. They need >>> SET CONSOLE SERIAL before they go for a serial console. Pulling the keyboard from the machine is not sufficient, like it is on most other Alpha models. Going back to a graphical console needs >>> SET CONSOLE GRAPHICS at the serial console. SCSI: For AS800 you want to check if your Ultra-Wide SCSI is indeed in Ultra mode. This can be done using the EEROMCFG.EXE utility that is on the Firmware Upgrade CDROM. For the AlphaServer1000/1000A/800 machines the kernel config file must contain: options DEC_1000A cpu EV4 # depends on the CPU model installed cpu EV5 # depends on the CPU model installed * * DS10/VS10/XP900 ("Webbrick") / XP1000 ("Monet") / DS10L ("Slate") * Webbrick and Monet are high performance workstations/servers based on the EV6 CPU and the Tsunami chipset. Tsunami is also used in much higher-end systems and as such has plenty of performance to offer. DS10, VS10 and XP900 are different names for essentially the same system. The difference are the software and options that are supported. DS10L is a DS10 based machine in a 1U high rackmount enclosure. DS10L is intended for ISPs and for HPTC clusters (e.g. Beowulf). Monet has, by 1999 standards, *stunning* (the words of a satisfied user) memory and I/O system bandwidth. ** Webbrick / Slate Features: - 21264 EV6 CPU at 466 MHz - L2 / Bcache: 2MB, ECC protected - memory bus: 128 bit via crossbar, 1.3GB/sec to memory - memory: industry standard 200 pin 83 MHz buffered ECC SDRAM DIMMs 4 DIMM slots (2 for DS10L) installed in pairs of 2 max memory is 2 Gb (1Gb for DS10L) - 21271 Core Logic chipset ("Tsunami") - 2 on-board 21143 Fast Ethernet controllers - AcerLabs M5237 (Aladdin-V) USB controller - AcerLabs M1533 PCI-ISA bridge - AcerLabs Aladdin ATA-33 controller - embedded dual EIDE - expansion: 3 64-bit PCI slots 1 32-bit PCI slots DS10L has a single 64bit PCI slot - 2x 16550A serial ports - 1x parallel port - 2x USB - PS/2 keyboard & mouse port Power: The system has a smart power controller. This means that parts of the system remain powered when it is switched off (like an ATX-style PC power supply). Before servicing the machine remove the power cord. Case: Webbrick is shipped in a desktop-style case similar to the older 21164 "Maverick" workstations but which offers much better access to components. If you intend to build a farm you can rackmount them in a 19" rack, they are 3U high. Slate is 1U high but has only one PCI slot. Memory: DS10 has 4 DIMM slots. DIMMs are installed as pairs. Please note that DIMM pairs are not installed in adjacent DIMM sockets but rather physically interleaved. DIMM sizes of 32, 64, 128, 256 and 512 Mbytes are supported. When 2 pairs of identical-sized DIMMs are installed DS10 will use memory interleaving for higher performance. DS10L, which has only 2 DIMM slots cannot do interleaving. SCSI: Starting with SRM firmware version 5.9 you can boot from Adaptec 2940-series adapters in addition to the usual set of Qlogic and Symbios/NCR adapters. EIDE: The base model comes with a FUJITSU 9.5GB ATA disk as its boot device. FreeBSD/alpha works just fine using EIDE disks on Webbrick. DS10 has 2 IDE interfaces on the mainboard. Expansion: On the PCI bus 32 and 64 bit cards are supported, in 3.3V and 5V variants. USB: Is supported in FreeBSD 4.1 and later.

SCSI: The on-board Qlogic UW-SCSI chip supports up to 4 internal devices. There is no external connector for the on-board SCSI. Memory: For 500 MHz CPUs 83 MHz DIMMs will do. Compaq specifies PC100 DIMMs for all CPU speeds. DIMMs are installed in sets of 4, starting with the DIMM slots marked '0'. Memory capacity is max 4 Gb. DIMMs are installed 'physically interleaved', note the markings of the slots. Memory bandwidth of Monet is twice that of Webbrick. The DIMMs live on the CPU daughter-card. Note that the system uses ECC RAM so you need DIMMs with 72 bits (not the PC-class 64 bit DIMMs) EIDE: Is usable / bootable for system disk so FreeBSD can be rooted on an EIDE disk. Although the Cypress chip has potential for 2 EIDE channels Monet uses only one of them. USB: If you experience problems trying to use the USB interface please check if the SRM variable "usb_enable" is set to "on". You can change this by performing: "set usb_enable on" at the SRM >>> prompt. Expansion caveats: - Don't try to use Symbios-chip based SCSI adapters in the PCI slots connected to hose 1. There is a not-yet-found FreeBSD bug that prevents this from working correctly. - Not all VGA cards will work behind the PCI-PCI bridge (so in slots 4 & 5). Only cards that implement VGA-legacy addressing correctly will work. Workaround is to put the VGA card 'before' the bridge. Sound: The sound chip is not currently supported with FreeBSD. There is work in progress in this area. The kernel config file must contain: options DEC_ST6600 cpu EV5 Contrary to expectation there is no 'cpu EV6' defined for inclusion in the kernel config file. The 'cpu EV5' is mandatory to keep config(8) happy. ** DS20/DS20E ("Goldrush"): Features: - 21264 EV6 CPU at 500 or 670 MHz - dual CPU capable machine - L2 / Bcache: 4 Mbytes per CPU - memory bus: dual 256 bit wide with crossbar switch - memory: SDRAM DIMMs installed in sets of 4 uses ECC 16 DIMM slots max. 4Gb - 21271 Core Logic chip-set ("Tsunami") - embedded Adaptec ? Wide Ultra SCSI - expansion: 2 independent PCI buses, driven by high-speed I/O channels called 'hoses' 6 64-bit PCI slots (3 per hose) 1 ISA slot Console: DS20 needs >>> SET CONSOLE SERIAL before it goes for a serial console. Pulling the keyboard from the machine is not sufficient. Going back to a graphical console needs >>> SET CONSOLE GRAPHICS at the serial console. Confusing is the fact that you will get SRM console output on the graphics console with the console set to serial, but when FreeBSD boots it honors the CONSOLE variable setting and all the boot messages as well as the login prompt will go to the serial port. Case: DS20 is housed in a fat cube-like enclosure. The enclosure also contains a StorageWorks SCSI hot-swap shelf for a maximum of 7 3.5" SCSI devices. DS20E is a sleeker case, without the StorageWorks shelf. Embedded SCSI: The embedded Adaptec SCSI chip on DS20 is disabled and is therefore not usable under FreeBSD. Starting with SRM firmware version 5.9 you can boot from Adaptec 2940-series adapters in addition to the usual set of Qlogic and Symbios/NCR adapters. This unfortunately does not include the embedded Adaptec SCSI chips. CPU: DS20 can have 2 CPUs installed. FreeBSD/alpha is not currently SMP-capable and will only use the primary CPU. Memory: If you are using banks of DIMMs of different sizes the biggest DIMMs should be installed in the DIMM slots marked '0' on the mainboard. The DIMM slots should be filled 'in order' so after bank 0 install in bank 1 and so on. Expansion: Don't try to use Symbios-chip based SCSI adapters in the PCI slots connected to hose 1. There is a not-yet-found FreeBSD bug that prevents this from working correctly. DS20 ships by default with a Symbios on hose 1 so you have to move this card before you can install/boot FreeBSD on it.

This is medium iron, not a hobbyist system. These are multi-CPU machines, up to 2 CPUs (AS2000) or 4 CPUs (2100[A]) can be installed. Both floor-standing and 19" rackmount boxes exist. Rackmount variations have different numbers of I/O expansion slots, different max number of CPUs and different maximum memory size. Some of the boxes come with an integral StorageWorks shelf to house hot-swap SCSI disks. There was an upgrade program available to convert your Sable machine into a Lynx by swapping the I/O backplane (the C-bus backplane remains). CPU upgrades were available as well. Features: - 21064 EV4[5] CPU[s] at 200, 233, 275 MHz - 21164 EV5[6] CPU[s]s at 250, 300, 375, 400 MHz - cache: varies in size with the CPU model; 1, 4 or 8Mbyte per CPU - embedded floppy controller driving a 2.88 Mbytes drive - embedded 10Mbit 21040 Ethernet [AS2100 only] - 2 serial ports - 1 parallel port - PS/2 style keyboard & mouse port NOTE: Lynx support is currently flagged as experimental due to lack of testing / test hardware. CPU: The CPUs spec-ed as 200 MHz are in reality running at 190 MHz. Maximum number of CPUs is 4. All CPUs must be of the same type/speed. Currently FreeBSD only uses one CPU in a multiprocessor machine. If any of the processors are ever marked as failed, they will remain marked as failed even after they have been replaced (or reseated) until you issue the command 'clear_error all' on the SRM console and power-cycle the machine. This may be true for other modules (IO and memory) as well, but it has not been verified. Memory: The machines use dedicated memory boards. These boards live on a 128 bit C-bus shared with the CPU boards. DemiSable supports up to 1Gb, Sable up to 2Gb. One of the memory bus slots can either hold a CPU or a memory card. A 4 CPU machine can have a maximum of 2 memory boards. Some memory board modules house SIMMs. These are called SIMM carriers. There are also memory modules that have soldered-on memory chips instead of SIMMs. These are called 'flat memory modules'. SIMM boards are used in sets of eight 72-pin 36 bit FPM memory of 70ns or faster. SIMM types supported are 1Mb x36 bit (4 Mbyte) and 4Mb x36 bit (16 Mbyte). Each memory board can house 4 banks of SIMMs. SIMM sizes can not be mixed on a single memory board. The first memory module must be filled with SIMMs before starting to fill the next memory module. Note that the spacing between the slots is not that big, so make sure your SIMMs fit physically (before buying them..) Console: Both Lynx and Sable are somewhat stubborn when it comes to serial consoles. They need >>> SET CONSOLE SERIAL before they go for a serial console. Pulling the keyboard from the machine is not sufficient, like it is on most other Alpha models. Going back to a graphical console needs >>> SET CONSOLE GRAPHICS at the serial console. On Lynx keep the VGA card in one of the primary PCI slots. The machines are equipped with a small OCP (Operator Control Panel) LCD screen. On this screen the self-test messages are displayed during system initialization. You can put your own little text there by using the SRM: >>> SET OCP_TEXT "FreeBSD" The SRM >>> SHOW FRU command produces an overview of your configuration with module serial numbers, hardware revisions and error log counts. Embedded SCSI: Both Sable, DemiSable and Lynx have Symbios 810 based Fast SCSI on-board. Check if it is set to Fast SCSI speed by >>> SHOW PKA0_FAST. If set to 1 it is negotiating for Fast speeds. >>> SET PKA0_FAST 1 enables Fast speeds. Internal disk storage: AS2100[A] come equipped with a StorageWorks 7 slot SCSI cage. A second cage can be added inside the cabinet. AS2000 has a single 7 slot SCSI cage, which cannot be expanded with an additional one. Note that the slot locations in these cages map differently to SCSI IDs compared to the standard StorageWorks shelves. Slot IDs from top to bottom are 0, 4, 1, 5, 2, 6, 3 when using a single bus configuration. The cage can also be set to provide two independent SCSI buses. This is used for embedded RAID controllers like the KZPSC (Mylex DAC960). Slot ID assignments for split bus are, from top to bottom: 0A, 0B, 1A, 1B, 2A, 2B, 3A, 3B. Where A and B signify a SCSI bus. In a single bus configuration the terminator module on the back of the SCSI cage is on the TOP. The jumper module is on the BOTTOM. For split bus operation these two modules are reversed. The terminator can be distinguished from the jumper by noting the chips on the terminator. The jumper does not have any active components on it. Expansion: DemiSable has 7 EISA slots and 3 PCI slots. Sable has 8 EISA and 3 PCI slots. Lynx, being newer, has 8 PCI and 3 EISA slots. The Lynx PCI slots are grouped in sets of 4. The 4 PCI slots closest to the CPU/memory slots are the primary slots, so logically before the PCI bridge chip. Note that contrary to expectation the primary PCI slots are the highest numbered ones (PCI4 - PCI7). Make sure you run the EISA Configuration Utility (from floppy) when adding/change expansion cards in EISA slots or after upgrading your console firmware. This is done by inserting the ECU floppy and typing RUNECU at the SRM >>> prompt. NOTE: EISA slots are currently unsupported, but the Compaq Qvision EISA VGA adapter is treated as an ISA device. It therefore works OK as a console. A special Extended I/O module for use on the C-bus was planned-for. Whether they ever saw daylight is unknown. In any case FreeBSD has never been verified with an ExtIO module. Power: The machines can be equipped with redundant power supplies. Note that the enclosure is equipped with interlock switches that switch off power when the enclosure is opened. The system's cooling fans are speed controlled. When the machine has more than 2 CPUs and more than 1 memory board dual power supplies are mandatory. The kernel config file must contain: options DEC_2100_A500 cpu EV4 cpu EV5 * * AlphaServer 4100 ("Rawhide") * The AlphaServer 4100 machine is aimed as an enterprise server. Expect a 30" high pedestal cabinet or alternatively the same system box in a 19" rack. This is medium iron, not a hobbyist system. These are multi-CPU machines, up to 4 CPUs can be in a single machine. Basic disk storage is housed in one or two StorageWorks shelves at the bottom of the pedestal. The Rawhides intended for the NT market are designated DIGITAL Server 7300 (5/400 CPU), DIGITAL Server 7305 (5/533 CPU). A trailing R on the part-number means a rackmount variant. Features: - 21164 EV5 CPUs at 266, 300 MHz 21164A EV56 CPUs at 400, 466, 533, 600 and 666 Mhz - cache: 4 Mbytes per CPU (EV5 300 MHz was also available cache-less) 8 Mbytes (EV5 600Mhz only) - memory bus: 128 bit with ECC - embedded floppy controller - 2 serial ports - 1 parallel port - PS/2 style keyboard & mouse port CPU: Rawhide is a multiprocessor machine. Currently FreeBSD only uses one CPU. Memory: Rawhide uses a maximum of 8 RAM modules. These modules are used in pairs and supply 72 bits to the bus (this includes ECC bits). Memory can be EDO RAM or synchronous DRAM. A fully populated Rawhide has 4 pairs of memory modules. Given the choice use SDRAM for best performance. The highest capacity memory board must be in memory slot 0. A mix of memory board sizes is allowed. A mix of EDO and SDRAM is also reported as working (assuming you don't try to mix EDO and SDRAM in one module pair). Embedded SCSI: Rawhide has an embedded Symbios 810 Fast SCSI bus. Expansion: Rawhides are available with a 8 64-bit PCI / 3 EISA slot expansion backplanes (called 'Saddle' modules). There are 2 separate PCI buses, PCI0 and PCI1. PCI0 has 1 dedicated PCI slot and (shared) 3 PCI/EISA slots. PCI0 also has a PCI/EISA bridge that drives things like the serial and parallel ports, keyboard/mouse etc. PCI1 has 4 PCI slots and an Symbios 810 SCSI chip. VGA console cards must be installed in a slot connected to PCI0. The current implementation has problems in handling PCI bridges. There is currently a limited fix in place which allows for single level, single device PCI bridges. The fix allows for the Digital supplied Qlogic SCSI card which sits behind a 21054 PCI bridge chip. NOTE: EISA slots are currently unsupported, but the Compaq Qvision EISA VGA adapter is treated as an ISA device. It therefore works OK as a console. Power: The system employs an I2C based power controller system. If you want to be sure all power is removed from the system pull the mains cables from the system. The kernel config file must contain: options DEC_KN300 cpu EV5 * * AlphaServer 1200 ("Tincup") and AlphaStation 1200 ("DaVinci") * The AlphaServer 1200 machine is the successor to the AlphaServer 1000A. It uses the same enclosure the 1000A uses, but the logic is based on the AlphaServer 4000 design. These are multi-CPU machines, up to 2 CPUs can be in a single machine. Basic disk storage is housed in a StorageWorks shelves The AS1200 intended for the NT market are designated DIGITAL Server 5300 (5/400 CPU) and DIGITAL Server 5305 (5/533 CPU). Features: - 21164A EV56 CPUs at 400 or 533 Mhz - cache: 4 Mbytes per CPU - memory bus: 128 bit with ECC DIMM memory on two memory daughter boards - embedded floppy controller - 2 serial ports - 1 parallel port - PS/2 style keyboard & mouse port CPU: AS1200 is a multiprocessor-capable machine. Currently FreeBSD only uses one CPU. Memory: AS1200 uses 2 memory daughter cards. On each of these cards are 8 DIMM slots. DIMMs must be installed in pairs. The maximum memory size is 4 Gbytes. Slots must be filled in order and slot 0 must contain the largest size DIMM if different sized DIMMs are used. AS1200 employs fixed starting addresses for DIMMs, each DIMM pair starts at a 512 Mbyte boundary. This means that if DIMMs smaller than 256 Mbyte are used the system's physical memory map will contain 'holes'. Supported DIMM sizes are 64 Mbytes and 256 Mbytes. The DIMMs are 72 bit SDRAM based, as the system employs ECC. Embedded SCSI: AS1200 has an embedded Symbios 810 Fast SCSI bus. Expansion: AS1200 has 5 64-bit PCI slots, one 1 32-bit PCI slot and one EISA slot (which is physically shared with one of the 64-bit PCI slots). There are 2 separate PCI buses, PCI0 and PCI1. PCI0 has the 32-bit PCI slot and the 2 top-most 64-bit PCI slots. PCI0 also has an Intel 82375EB PCI/EISA bridge that drives things like the serial and parallel ports, keyboard/mouse etc. PCI1 has 4 64-bit PCI slots and an Symbios 810 SCSI chip. VGA console cards must be installed in a slot connected to PCI0. Power: The system employs an I2C based power controller system. If you want to be sure all power is removed from the system pull the mains cables from the system. Tincup uses dual power supplies in load-sharing mode and not as a redundancy pair. The kernel config file must contain: options DEC_KN300 cpu EV5 * * AlphaServer 8200 and 8400 ("TurboLaser") * The AlphaServer 8200 and 8400 machines are aimed as enterprise servers. Expect a tall 19" cabinet (8200) or fat (8400) 19" rack. This is big iron, not a hobbyist system. These are multi-CPU machines, up to 12 CPUs can be in a single machine. The TurboLaser System Bus (TLSB) allows 9 nodes on the AS8400 and 5 nodes on the AS8200. TLSB is 256 bit data, 40 bit address allowing 2.1 Gbytes/sec. Nodes on the TLSB can be CPUs, memory or I/O. A maximum of 3 I/O ports are supported on a TLSB. Basic disk storage is housed in a StorageWorks shelf. Features: - 21164 EV5 CPUs at up to 467 MHz 21264 EV67 CPUs at up to 625 MHz one or two CPUs per CPU module - cache: 4Mbytes per CPU - memory bus: 256 bit with ECC - memory: uses big memory modules that plug into the TLSB, which in turn hold special SIMM modules. memory modules come in varying sizes, up to 2 Gbytes a piece. uses ECC (8 bites per 64 bits of data) 7 modules max for AS8400, 3 modules max for AS8200 maximum memory is 14 Gbytes - expansion: 3 system 'I/O ports' that allow up to 12 I/O channels each I/O channel can connect to XMI, Futurebus+ or PCI boxes Memory: FreeBSD supports (and has been tested with) up to 2 Gbytes of memory on TurboLaser. CPU: TurboLaser is very much a multiprocessor machine. Currently FreeBSD only uses one CPU. Expansion: Only PCI expansion is supported on FreeBSD. XMI or Futurebus+ (which are AS8400 only) are both unsupported. The I/O port modules are designated KFTIA or KFTHA. The I/O port modules supply so called 'hoses' that connect to up to 4 (KFTHA) PCI buses or 1 PCI bus (KFTIA). KFTIA has embedded dual 10baseT Ethernet, single FDDI, 3 SCSI Fast Wide Differential SCSI buses and a single Fast Wide Single Ended SCSI bus. The FWSE SCSI is intended for the systems CDROM. KFTHA can drive via each of its 4 hoses a DWLPA or DWLPB box. The DWLPx house a 12 slots 32 bit PCI backplane. Physically the 12 slots are 3 4-slot buses but to the software it appears as a single 12 slots PCI bus. A fully expanded AS8x00 can have 3 (I/O ports) times 4 (hoses) times 12 (PCI slots/DWLPx) = 144 PCI slots. The maximum bandwidth per KFTHA is 500 Mbytes/second. DWLPA can also house 8 EISA cards, 2 slots are PCI-only, 2 slots are EISA only. Of the 12 slots 2 are always occupied by an I/O and connector module. For best performance distribute high bandwidth (FibreChannel, Gigabit Ethernet) over multiple hoses and/or multiple KFTHA/KFTIA. Currently PCI expansion cards containing PCI bridges are not usable. Don't use them at this time. Embedded SCSI: The single ended SCSI bus on the KFTIA will turn up as the fourth (!) SCSI bus. The 3 differential SCSI buses of the KFTIA precede it. Console: AS8x00 are generally run with serial consoles. Some newer machines might have a graphical console of some sorts but FreeBSD has only been tested on a serial console. For serial console usage either change /etc/ttys to have: console "/usr/libexec/getty std.9600" unknown on secure as the console entry, or add zs0 "/usr/libexec/getty std.9600" unknown on secure and make the zs node: mknod /dev/zs0 c 135 0 For the AlphaServer 8x00 machines the kernel config file must contain: options DEC_KN8AE # Alpha 8200/8400 (Turbolaser) cpu EV5 * * Alpha Processor Inc.

Features: - 21264a Alpha CPU at 600 or 700 MHz in a Slot B module (includes cooling fans) - memory bus: 128 bits to the L2 cache, 64 bits from Slot B to the AMD-751 - on-board Bcache / L2 cache: 2Mb (600Mhz) or 4Mb (700Mhz) cache - AMD AMD-751 ('Irongate') system controller chip - Acer Labs M1543C PCI-ISA bridge controller / super-IO chip - PS/2 mouse & keyboard port - memory: 168-pin PC100 unbuffered SDRAM DIMMS 3 DIMM slots DIMM sizes supported are 64, 128 or 256 Mb in size - 2x 16550A serial port - 1x ECP/EPP parallel port - floppy interface - 2x embedded Ultra DMA33 IDE interface - 2x USB port - expansion: 4 32 bit PCI slots 2 ISA slots 1 AGP slot Slot B: Slot B is a box-like enclosure that houses a daughter-board for the CPU and cache. It has 2 small fans for cooling. Loud ones too.. Memory: The machine needs ECC capable DIMMs, so 72 bit ones. This does not appear to be documented in the UP1000 docs. The system accesses the serial EEPROM on the DIMMs via the SM bus. Note that if only a single DIMM is used it must be installed in slot *2*. This is a bit counter-intuitive. Power The UP1000 needs a 400Watt ATX power supply according to the manufacturer. This might be a bit overly conservative/pessimistic judging from the power consumption of the board & cpu. But as always you will have to take your expansion cards and peripherals into account. The M1543C chip contains power management functionality & temperature monitoring (via I2C / SM bus). Console Chances are that your UP1000 comes by default with AlphaBios only. The SRM console firmware is available from the Alpha Processor Inc. website. It is currently available in a beta version which was successfully used during the port of FreeBSD to the UP1000. EIDE: The embedded Ultra DMA EIDE ports are bootable by the SRM console. SCSI: UP1000 SRM can boot off an Adaptec 294x adapter. Under high I/O load conditions machine lockups have been observed using the Adaptec 294x. A Symbios 875 based card works just fine, using either the ncr or sym driver. The sym driver is the newest and most actively maintained one. Most likely other cards based on the Symbios chips that the sym driver supports will work as well. USB: Is disabled by the SRM console and has not (yet) been tested with FreeBSD.

CS20 * The CS20 is a 19", 1U high rackmount server based on the 21264[ab] CPU. It can have a maximum of 2 CPUs. Features: - 21264a Alpha CPU at 667 MHz or 21264b 833 MHz (max. 2 CPUs) - memory bus: 100MHz 256-bit wide - 21271 Core Logic chipset ("Tsunami") - Acer Labs M1533 PCI-ISA bridge controller / super-IO chip - PS/2 mouse & keyboard port - memory: 168-pin PC100 PLL buffered/registered SDRAM DIMMS 8 DIMM slots uses ECC memory min 256 Mbytes / max 2 Gbytes of memory - 2x 16550A serial port - 1x ECP/EPP parallel port - ALI M1543C Ultra DMA66 IDE interface - embedded dual Intel 82559 10/100Mbit Ethernet - embedded Symbios 53C1000 Ultra160 SCSI controller - expansion: 2 64 bit PCI slots (2/3 length) CPU: The CS20 can have 2 CPUs installed. FreeBSD/alpha is not currently SMP-capable and will only use the primary CPU. Console: SRM console code comes standard with the CS20. The SRM lives in 2Mbytes of flash ROM. Memory: The CS20 needs ECC capable DIMMs. Note that it uses *buffered* DIMMs. Monitoring: The CS20 has an I2C based internal monitoring system for things like temperature, fans, voltages etc. The I2C also supports 'wake on LAN'. Expansion: Each PCI slot is connected to it's own independent PCI bus on the Tsunami. EIDE: The embedded Ultra DMA EIDE ports are bootable by the SRM console. Disks: The CS20 has an embedded slim-line IDE CD drive. There is a front-accessible bay for a 1" high 3.5" SCSI hard-disk drive with SCA connector. Note that there is no floppy disk drive (or a connector to add one). The kernel config file must contain: options DEC_ST6600 cpu EV5 Contrary to expectation there is no 'cpu EV6' defined for inclusion in the kernel config file. The 'cpu EV5' is mandatory to keep config(8) happy. Supported hardware overview --------------------------- Word of caution: the installed base for FreeBSD/alpha is not nearly as large as for FreeBSD/Intel. This means that the enormous variation of PCI/ISA expansion cards out there has much less chance of having been tested on alpha than on Intel. This is not to imply they are doomed to fail, just that the chance of running into something never tested before is much greater. GENERIC contains things that are known to work on Alpha only. - Expansion buses: PCI and ISA are fully supported. Turbo Channel is not in GENERIC and has limited support (see the relevant machine model info). The MCA bus is not supported. The EISA bus is not supported for use with EISA expansion cards as the EISA support code is lacking. ISA cards in EISA slots are reported to work. The Compaq Qvision EISA VGA card is driven in ISA mode and works OK as a console. - Floppy drives: 1.44 Mbyte and 1.2 Mbyte floppy drives are supported. 2.88Mbyte drives sometimes found in Alpha machines are supported up to 1.44Mbyte. - ATA / ATAPI (IDE): are supported via the ata driver framework. As most people run their Alphas with SCSI disks it is not as well tested as SCSI. Be aware of boot-ability restrictions for IDE disks. See the machine specific information. - SCSI: full support via the CAM layer for Adaptec 2940x (AIC7xxx chip-based), Qlogic family and Symbios. Be aware of the machine-specific boot-ability issues for the various adapter types. - FibreChannel: the Qlogic QL2x00 FibreChannel host adapters are fully supported. - Ethernet: if you want to boot your Alpha over the Ethernet you will obviously need an Ethernet card that the SRM console recognizes. This generally means you need a board with an 21x4x Ethernet chip as that is what Digital used. These chips are driven by the FreeBSD 'de' (older driver) or 'dc' (newer driver). Some new SRM versions are known to recognize the Intel 8255x Ethernet chips as driven by the FreeBSD 'fxp' driver. But beware: the 'fxp' driver is reported not to work correctly with FreeBSD/alpha (although it works excellently on FreeBSD/x86). - FDDI: DEC DEFPA PCI FDDI network adapters are supported on alpha. - graphics console/keyboard/mouse: in general the SRM console emulates a VGA-compatibility mode on PCI VGA cards. This is, however, not guaranteed to work by Compaq/DEC for each and every card type out there. When the SRM thinks the VGA is acceptable FreeBSD will be able to use it. The console driver works just like on a FreeBSD/intel machine. The TGA video graphics which is embedded on for example Multia does *not* work with FreeBSD. TGA based PCI cards are also *not* supported. Please note that VESA modes are not supported on Alpha, so that leaves you with 80x25 consoles - serial ports: the 'PC standard' serial ports found on most Alphas are supported. For TurboChannel machines the serial ports are also supported. - ISDN (i4b): is not supported on FreeBSD/alpha Acknowledgments ---------------- In compiling this file I used multiple information sources, but http://www.netbsd.org proved to be an invaluable source of information. If it wasn't for NetBSD/alpha there probably would not be a FreeBSD/alpha in the first place.
