according to the setting of the Send Start Unit Command. SCSISelect remains available if needed. The following options have no effect if the SCSI card BIOS is disabled. (The SCSI card BIOS is normally enabled by default.) Domain Validation-(Default: Enabled) Determines the optimal transfer rate for each device on the SCSI bus and sets transfer rates accordingly. When enabled, this option is available if it is implemented in the device drivers. However, this option is not supported by the BIOS. Support Removable Disks Under INT 13 as Fixed Disks-(Default: Disabled) Determines which removablemedia drives are supported by the SCSI card BIOS. The options are as follows: Disabled- No removable-media drives running under DOS are treated as hard disk drives. Software drivers are required because the drives are not controlled by the BIOS. NOTICE: You may lose data if you remove a removable-media cartridge from a SCSI drive controlled by the SCSI card BIOS while the drive is on. If you want to be able to remove the media while the drive is on, install the removable-media software driver and set Support Removable Disks Under BIOS as Fixed Disks 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 supported by the BIOS are treated as hard disk drives. NOTE: The Boot Only and All Disks options are available only if the SCSI Controller BIOS option is set to Enabled. BIOS Support for Bootable CD-ROM-(Default: Enabled) When set to Enabled, the SCSI card BIOS allows the system to boot from a CD-ROM drive. If booting from a hard disk or other device, make sure no bootable CD is inserted, or disable this option. Using HostRAID Settings After scanning the device is completed, the Main menu displays the following information: ID-indicates ID number of hard drive. Type-indicates available nonarray hard drive, RAID type, or global spare: Striped (R0) Mirrored (R1) Hard Drive Spare Vendor-indicates vendor of hard drive. Product-indicates model of hard drive or name of built array. Size-indicates size of hard drive. Status-indicates available RAID status: Free-available drive Optimal-no defect Degraded-one drive in a mirrored array is in failed status, and a Rebuild option is available. Dead-One drive in a RAID 0 array is in failed state or missing.

The following options have no effect if the SCSI card BIOS is disabled. (The SCSI card BIOS is normally enabled by
default.)
Domain Validation
—(Default: Enabled) Determines the optimal transfer rate for each device on the SCSI bus
and sets transfer rates accordingly. When enabled, this option is available if it is implemented in the device
drivers. However, this option is not supported by the BIOS.
Support Removable Disks Under INT 13 as Fixed Disks
—(Default: Disabled) Determines which removable-
media drives are supported by the SCSI card BIOS. The options are as follows:
Disabled
— No removable-media drives running under DOS are treated as hard disk drives. Software
drivers are required because the drives are not controlled by the BIOS.
NOTICE: You may lose data if you remove a removable-media cartridge from a SCSI drive controlled by the
SCSI card BIOS while the drive is on. If you want to be able to remove the media while the drive is on, install
the removable-media software driver and set Support Removable Disks Under BIOS as Fixed Disks 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 supported by the BIOS are treated as hard disk drives.
NOTE: The Boot Only and All Disks options are available only if the SCSI Controller BIOS option is set to
Enabled.
BIOS Support for Bootable CD-ROM
—(Default: Enabled) When set to Enabled, the SCSI card BIOS allows
the system to boot from a CD-ROM drive. If booting from a hard disk or other device, make sure no bootable
CD is inserted, or disable this option.
