Adaptec Ultra320 SCSI Cards User's Guide
SCSI Controller INT 13 Support—(Default: Enabled) This
option controls the state of the BIOS at POST time. The
following settings are available:
Enabled—Supports INT 13 for booting from a SCSI hard
disk drive connected to the SCSI card. If you use this option,
the following options are available:
Extended INT 13 Translation for DOS Drives > 1 GB
Support Removable Disks Under INT 13 as Fixed Disks
BIOS Support for Bootable CD-ROM
Disabled:NOT Scan—Select this option if all the devices on
the SCSI bus (for example, CD-ROM drives) are controlled
by software drivers and do not need the BIOS, and you do
not want the BIOS to scan the SCSI bus. SCSISelect remains
available if needed.
Disabled:Scan Bus—Select this option if all the devices on
the SCSI bus (for example, CD-ROM drives) are controlled
by software drivers and you need the BIOS to scan the SCSI
bus. Allows devices to spin up according to the setting of the
Send Start Unit Command. SCSISelect remains available if
needed.
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.
