Configuring the Adaptec SCSI Card 19160 with SCSISelect
Host Adapter BIOS (Configuration Utility Reserves BIOS
Space)—(Default: Enabled) Enables or disables the SCSI card
BIOS.
Leave at Enabled to allow the SCSI card BIOS to scan and
initialize all SCSI devices.
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.
Support Removable Disks Under BIOS as Fixed Disks—
(Default: Disabled) Determines which removable-media drives
are supported by the SCSI card BIOS. Choices are as follows:
Disabled— No removable-media drives are treated as hard
disk drives. Software drivers are required because the
drives are not controlled by the BIOS.
Caution:
You may lose data if you remove a removable-
media cartridge from a SCSI drive controlled by the
SCSI card BIOS while the drive is on. If you want to be
able to remove the media while the drive is on, install
the removable-media software driver and set Support
Removable Disks Under BIOS as Fixed Disks to
Disabled.
Boot Only—Only the removable-media drive designated
as the boot device is treated as a hard disk drive.
