change. The first table shows the global settings which impact your

host adapter and all SCSI devices connected to it. Be very careful if you

change any of these settings. The second table shows the device

settings which apply to individual devices.

Starting the SCSI Configuration Utility

You access the SCSI Configuration Utility by pressing when the

message Press F6 to start Configuration Utility... is

displayed during the PC Workstation’s start-up routine. A further

message is then displayed: Please wait, invoking Configuration

Utility... before the Main menu of the Symbios Logic SCSI

Configuration utility appears.

NOTE The items shown on your screen may be different from those shown

below.

Use the and keys and the key to make a selection

from this menu.

You can only select an adapter if the current status is “On”. Changes

Adapter Boot Order This option is only available when you have more than one host adapter

installed. It lets you set the order in which host adapters boot. When you

select this option the Boot Order menu is displayed.

To change an adapter’s boot order (from the Boot Order menu), select

it and press . You are then prompted to enter the new boot

sequence number. When you are satisfied with the boot order, press

to exit this menu.

Change Adapter Status This option lets you activate or deactivate a host adapter and all SCSI

devices attached to it. The change takes place after a reboot, which is

automatic when you exit from the Configuration utility after using this

option to make a change. When you select this option the Change Status

on Next Boot menu is displayed.

To toggle an adapter’s status ‘on’ or ‘off’ (from the Change Status on

Next Boot menu), select it and press . When you are satisfied

with your selections, press to exit this menu.

Display Mode This option determines how much information about your host

adapter(s) and SCSI devices is displayed on the screen during the PC

Workstation’s start-up routine. For more complete information, select

the verbose setting; for a faster boot, select the terse setting.

Mono/Color This option lets you choose between a black and white or a color display

for the SCSI configuration utility. If you are using a black and white

monitor, you may need to select the mono setting to get a more readable

screen.

Help This option displays a help screen giving information about the Main

menu.

Quit This option exits the SCSI Configuration utility.

Adapter Setup Menu

When you select Adapter Setup from the Adapter Utilities menu, the

Adapter Setup menu is displayed:

The settings in this menu are global settings that effect the selected

host adapter and all SCSI devices attached to it.

SCAM Support The Symbios Logic BIOS version 4.x and above supports the SCSI Plug

and Play protocol called SCAM (SCSI Configured AutoMatically). You

can turn this off if you wish.

Parity Symbios Logic PCI to SCSI host adapters always generate parity, but

some SCSI devices do not. For this reason you can disable parity

checking.

NOTE When disabling parity checking, you may have to disable disconnects for

certain devices as parity checking for the re-selection phase is not

disabled. If a device does not generate parity, and it disconnects, the I/O

never completes because the re-selection never completes.

HP Kayak XA- 05xx PC Workstation — Configuring a SCSI Accessory

Using the SCSI Configuration Utility (Selected Models)

Host SCSI ID In general it is not advisable to change your host adapter ID from the

default value of 7, as this gives it the highest priority on the SCSI bus.

However, if you have two adapters sharing the same SCSI devices, you

should give one of the adapters a currently-unassigned ID to avoid

duplication of SCSI IDs.

Scan Order This option lets you tell the host adapter BIOS and your device drivers

to scan the SCSI bus from low to high (0 to max) SCSI ID, or from high

to low (max to 0) SCSI ID. If you have more than one device on a SCSI

bus, changing the device order changes the drive letters which are

assigned to them by the system.This will change the boot order.

Removable Media

Support

Only used when removable disk drives are installed. For more

information, refer to the User’s Guide that came with you removable

disk drive.

CHS Mapping When performing a ‘low format’, CHS mapping should be set to

Alternate CHS Mapping for full compatibility with other SCSI

adapters. This is the default setting.
