 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.
 BIOS Support For Bootable CD-ROM
— 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
— Determines whether the host adapter
BIOS supports disks with more than 1024 cylinders. The default setting is
Enabled
.
 Support For Ultra SCSI Speed
— Determines whether the host adapter sup-
ports the fast transfer rates (20–40 MB/sec). The default setting is
Enabled
.

To access the SCSI disk utilities, select
SCSI Disk Utilities
from the menu that
appears when you start SCSISelect. When the option is selected, SCSISelect immedi-
ately scans the SCSI bus (to determine the devices installed) and displays a list of all
SCSI IDs and the device assigned to each ID.
When you select a specific ID and device, a menu appears, displaying the
Format
Disk
and
Verify Disk Media
options.

 Format Disk
— Runs a utility that allows you to perform a low-level format on a
hard-disk drive. Most SCSI disk drives are formatted at the factory and do not
need to be formatted again. The Adaptec Format Disk utility is compatible with
the majority of SCSI disk drives.
 Verify Disk Media
— Runs a utility that allows you to scan the media of a hard-
disk drive for defects. If the utility finds bad blocks on the media, it prompts you
to reassign them; if you select
Ye s
, those blocks are no longer used. You can
press <Esc> at any time to exit the utility.
