■
Set to Disabled: Not scan if the devices on the SCSI bus (for
example, CD-ROM drives) are controlled by software driv-
ers and do not need the BIOS, and you do not want the
BIOS to scan the SCSI bus.
■
Set to Disabled: Scan Bus if you do not need the BIOS, but
you want it to scan the SCSI devices on the bus.
The following four options have no effect when the SCSI Card BIOS
is disabled. (The SCSI Card BIOS is normally enabled by default.)
■
Domain Validation—(Default: Enabled) Determines the kinds
of SCSI devices connected and reduces data transfer speed
when legacy SCSI devices are detected. Displays the resulting
data transfer rate.

(Default: Disabled) Determines which removable-media drives
are supported by the SCSI card BIOS. Choices are as follows:

drives are not controlled by the BIOS.
Caution:

the removable-media software driver and set Support
Removable Disks Under BIOS as Fixed Disks to
Disabled.
■
