Chapter 3 Configuring the ASUS LS99 19
3. Configuration
• SCSI Controller Int 13 Support—(Default: Enabled) Enables or disables the
SCSI card BIOS. If you change this setting, the change automatically applies to
both SCSI channels.
• Leave on Enabled to enable the SCSI card BIOS and allow it 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 drivers 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 and you need to spin up the device.
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. Displays the
resulting data transfer rate. 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 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 Int 13 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.
• BIOS Support for Bootable CD-ROM—(Default: Enabled) When set to Enabled,
the SCSI card BIOS allows the computer to boot from a CD-ROM drive.
