Support Removable Disks Under BIOS as Fixed Disks —
This option controls which removable-media drives are
supported by the host adapter BIOS. This default setting 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.
Caution: If a removable-media SCSI device is controlled by the
host adapter BIOS, do not remove the media while the drive is on
or you may lose data! If you want to be able to remove media
while the drive is on, install your removable-media device driver
and set this option to Disabled.

Extended BIOS Translation for DOS Drives >1 Gbyte –
This option determines whether extended translation is
available for SCSI hard disks with capacities greater than 1
GByte. The default setting is Enabled.
Caution: If you decide to change the translation scheme, back up
your disk drives first! All data is erased when you change from
one translation scheme to another.
The standard translation scheme for SCSI host adapters provides
a maximum accessible capacity of 1 GByte. To support disk
drives larger than 1 GByte, the Ultra Wide SCSI includes an
extended translation scheme. This scheme supports disk drives
as large as 8 GBytes under MS_DOS with a maximum partition
size of 2 GBytes.
