NEC HX4500 manual Using the SCSISelect Utility, Bus Device Channel Selected Scsi Channel

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.

Tperform 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.

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.
