Configuring the SCSI
Interface
3 Troubleshooting Your PC Workstation and Using the Setup Program
Using the HP Setup Program
You can install and use a SCSI host adapter board, and also use the
integrated SCSI interface. However, if you want to use the SCSI host
adapter board only, you can disable the integrated SCSI interface. To
disable the integrated SCSI interface, highlight the
option and select

SCSI BIOS . . . . . . . . . . . . Not Available/Enabled
Ultra SCSI . . . . . . . . . . . Automatic/Enabled/Disabled
The use of Ultra SCSI (20 MB/s transfer rate) imposes restrictions on
SCSI bus traffic. By default, the system BIOS will ensure data integrity
by automatically disabling Ultra SCSI (to a 10 MB/s transfer rate)
whenever an external SCSI device is connected.
The field can be set to one of the following:
Ultra SCSI
(Default setting)
Automatic
Ultra SCSI is automatically disabled when the BIOS detects an
external SCSI device. Inversely, Ultra SCSI is automatically enabled
when no external SCSI device is detected. To avoid potential data
corruption problems, it is recommended that you keep this default
setting.
Enabled
Ultra SCSI is permanently enabled, regardless of the presence or
absence of external SCSI devices. To avoid data corruption, use this
setting with caution and only under the following conditions:
One to three SCSI devices — overall cable length
•
Four to seven SCSI devices — overall cable length
•
Disabled
Ultra SCSI is never enabled.
To access advanced SCSI device configuration options, restart the
computer and press
