Adaptec SBC-599, SBC-596 manual

nSupport 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.

nExtended 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.
