Installing and Configuring SCSI Drivers 3-7
‡
BIOS Multiple LUN Support — This option provides support for peripherals that
contain multiple SCSI devices, such as RAID subsystems and CD-ROM changers.
‡
Include in BIOS Scan — This option enables you to set whether the system BIOS
scans this device during system start-up. The default is Yes.

The advanced host adapter settings should not be changed unless absolutely neces-
sary. These values are set by Dell, and changing them may cause conflicts with the
SCSI devices.
‡
Host Adapter BIOS — This option enables or disables the host adapter BIOS. The
default is Enabled.
NOTE: Several SCSISelect options are not valid unless the host adapter BIOS is
enabled.
If you are booting from a SCSI hard-disk drive connected to the host adapter, the
BIOS must be enabled. You should disable the host adapter BIOS if the peripher-
als on the SCSI bus (for example, CD-ROM drives) are all controlled by device
drivers and do not need the BIOS.
‡
Support Removable Disks Under BIOS As Fixed Disks — This option controls
which removable-media drives are supported by the host adapter BIOS. The
default is Boot Only. The following choices are available.

— 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.
— Disabled. No removable-media drives are treated as hard-disk drives. In this
situation, software drivers are needed because the drives are not controlled
by the BIOS.
‡
Plug and Play SCAM Support — This option provides automatic configuration of
SCSI devices in operating systems that support Plug and Play. Dell recommends
that you leave this option set to Disabled.
‡
Reset SCSI Bus at IC Initialization — This option enables the SCSI bus to be reset
when the controller is initialized. The default is Enabled.
‡
Extended BIOS Translation For DOS Drives > 1 GB — This option determines
whether extended translation is available for SCSI hard-disk drives with capacities
greater than 1 gigabyte (GB). The default is Enabled.
When you partition a hard-disk drive larger than 1 GB, use the MS-DOS fdisk util-
ity as you normally would. Because the cylinder size increases to 8 MB under
