Configuring the Adaptec SCSI Card 39320D with SCSISelect
The following options have no effect if the SCSI card BIOS is
disabled. (The SCSI card BIOS is normally enabled by default.)
■ Domain Validation—(Default: Enabled) Determines the optimal
transfer rate for each device on the SCSI bus and sets transfer
rates accordingly. When enabled, this option is available if it is
implemented in the device drivers. However, this option is not
supported by the BIOS. If you change this setting, the change
automatically applies to both SCSI channels.
■ Support Removable Disks Under INT 13 as Fixed Disks—
(Default: Disabled) Determines which removable-media drives
are supported by the SCSI card BIOS. The options are as
follows:
■ Disabled— No removable-media drives running under
DOS 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.
■ All Disks—All removable-media drives supported by the
BIOS are treated as hard disk drives. This setting has no
effect on drives under NetWare because NetWare
automatically supports removable-media drives as hard
disk drives.
Note: The Boot Only and All Disks options are available
only if the SCSI Controller BIOS option is enabled.
