Description

The Compaq family of PCI and EISA controllers based on the 53cxxx chip 
includes the following:

Compaq Controller                            Chip    Available On

Compaq 32-Bit Fast-SCSI-2                    53c710  EISA add-in card
Compaq Integrated 32-Bit Fast-SCSI-2         53c710  ProLiant 2000, 4000
Compaq Integrated 32-Bit Fast-SCSI-2/P       53c810  ProSignia 300-PCI, 500-PCI
Compaq Integrated 32-Bit Fast-Wide SCSI-2/E  53c825  ProLiant 4500-EISA
Compaq Integrated 32-Bit Fast-Wide SCSI-2/P  53c825  ProLiant 1500-PCI
Compaq 32-Bit Fast-Wide SCSI-2/P             53c825  PCI add-in card

Note - The Wide SCSI option is not supported under the Solaris Operating
environment. Some cards include connectors for both narrow cables (in other
words, 8-bit SCSI A cables) and wide cables (that is 16-bit SCSI P cables.) You
can connect devices to the SCSI Wide connectors using SCSI P cables, but the
Solaris ncrs driver will not initiate or accept the Wide Data Transfer option.
The attached devices will function in 8-bit narrow mode.

Device Configuration

Preparing for Configuration

See the hardware manufacturer's documentation for installation and cabling 
requirements. 

Configuring the Device

1.  Consult your Device Configuration Worksheet to see if the controller's
    settings need to be changed.

2.  Use the Compaq EISA configuration utility Version 2.20 Revision B or 
    later. 

    This can be run from the hard disk or from the diskettes that come with 
    your system. 

3.  At the MAIN MENU, press ctrl-A to see the Advanced Mode options.

    A pop-up box shows that Advanced Mode is enabled.

4.  Press Enter.

5.  Select System Configuration.

6.  Select Configure Hardware.

    The program will then ask you to insert the second diskette into the drive.

7.  Press Enter after you have inserted the second diskette.

8.  Select Configuration Set Up.

9.  Select Step 2 Add/Remove Board.

    Follow the instructions on the screen to add your board.

10. Select Step 3 View or Edit Details. 

    Find the description of the slot with the controller. Use the Page-Down key
    as needed.

11. Select BIOS Hard Drive Geometry under the slot description that lists the 
    controller.

12. Set this option to <=1 GB: 64 Heads, 32 Sectors > 1GB: 255 Heads, 63
    sectors.

    This will work for disks with sizes greater and smaller than 1 Gbyte. 

13. Press F10 to leave that menu.

14. Select Step 5 Save and Exit.

    Save your changes and exit.
