3-14 Configuring Your System
SCSISelect Utility
The system I/O board includes an integrated AIC7895 dual SCSI host controller
used to manage SCSI devices in your system. When used, Channel A of this
controller provides support for four internally mounted ultra/wide hard disk
drives. Channel B provides support for internally mounted tape and CD-ROM
devices as well as externally connected SCSI devices.
The integrated SCSI host controller is configured using the SCSISelect utility.
Use the SCSISelect utility to:
„
change the SCSI host adapters default values.
„
check and/or change SCSI device settings for a particular device.
„
perform low-level formatting on SCSI disk devices.
„
perform verify operations on SCSI disk devices.
When disabling access to the SCSISelect Utility, the SCSISelect utility should
be used in conjunction with the BIOS Setup Utility. Changing the BIOS Setup
Utility “SCSI Select Utility Mask” parameter to Masked prevents the use of the
SCSI Select utility via Ctrl-A, but the “Press <Ctrl-A> for SCSI Select” prompt
is still displayed. Changing the SCSISelect utility “Display <Ctrl-A> Message
During BIOS Initialization” parameter to Disabled prevents the prompt from
being displayed. In combination these parameters can be used to prevent access
to the SCSISelect utility during boot.
Using the SCSISelect Utility
To run the SCSISelect Utility, perform the following procedure.
1.
Power-on the system. The system boots up.
2.
During initialization, press Ctrl + A . The SCSISelect Utility starts. When
SCSISelect detects the AIC-7895 host adapter, it displays a selection menu
listing the bus and device number of each channel. When the selection menu
appears, select the channel you wish to configure as follows.
Bus : Device : Channel Selected SCSI Channel
00 : 01 : A A
00 : 01 : B B
3.
Once you select the channel, the following screen is displayed.
