Chapter 9 SCSI Setup and Configurations 115
• Set to Disabled: Scan Bus if you do not need the BIOS, but you
want it to scan the SCSI devices on the bus and you need to spin
up the devices.
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 optimal
transfer rate for each device on the SCSI bus and sets transfer rates
accordingly. 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.
• 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.
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.
• BIOS Support for Bootable CD-ROMs—(Default: Enabled)
When set to Enabled, the SCSI card BIOS allows the computer to
boot from a CD-ROM drive.
• BIOS Support for Int 13 Extensions—(Default: Enabled) When
set to Enabled, the SCSI card BIOS supports Int 13h extensions as
required by Plug-and-Play. The setting can be either enabled or
disabled if your system is not Plug-and-Play.
