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 SCSI
Select
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
