You should disable the host adapter BIOS if the peripherals 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 setting is Boot Only. The following choices are available.

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.

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 sup- ported 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.

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 setting is Enabled.

CAUTION: Back up your hard-disk drive before you change the translation scheme. 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 GB. To support hard-disk drives larger than 1 GB, the 78xx series host adapters include an extended translation scheme that supports hard-disk drives as

large as 8 GB under the MS-DOS operating system with a maximum partition size of 2 GB.

Extended BIOS translation is used only with MS-DOS 5.0 or later. It is not necessary to enable this if you are using another operating system such as Novell NetWare.

When you partition a hard-disk drive larger than

1 GB, use the MS-DOS fdisk utility as you normally would. Because the cylinder size increases to 8 MB under extended translation, the partition size you choose must be a multiple of 8 MB. If you request a size that is not a multiple of 8 MB, fdisk rounds up to the nearest whole multiple of 8 MB.

Display <Ctrl><a> Message During BIOS Initializa- tion. This option determines whether the Press <Ctrl><a> for SCSISelect (TM) Util- ity! message appears on your screen during system start-up. The default setting is Enabled. If this setting is disabled, you can still run the SCSISelect utility by pressing <Ctrl><a> after the host adapter BIOS ban- ner appears.

Multiple LUN Support. This option determines whether your system supports booting from a SCSI device that has multiple LUNs. The default setting is Disabled. Enable this option if your boot device has multiple LUNs.

BIOS Support for Bootable CD-ROM. This option determines whether the host adapter BIOS provides support for booting from a CD-ROM drive. The default setting is Enabled.

BIOS Support for INT 13 Extensions. This option determines whether the host adapter BIOS supports disks with more than 1024 cylinders. The default set- ting is Enabled.

Support for ULTRA SCSI Speed. This option deter- mines whether the host adapter supports the fast transfer rates (20.0 to 40.0 megabits per second [Mbps]). The default setting is Enabled.

Starting the SCSISelect Utility

You can start the SCSISelect utility by pressing <Ctrl><a> when the following prompt appears briefly at boot time:

Press <Ctrl><a> for SCSISelect (TM) Utility!
