Lan Information - TYAN THUNDER I840 User Manual

• Domain Validation—(Default: Enabled) Determines what kinds of SCSI devices are connected and
reduces data transfer speed if it detects older legacy SCSI devices. Displays the resulting data
transfer rate. If you change this setting, the change automatically applies to both SCSI channels.
• Support Removable Disks Under BIOS as Fixed Disks—(Default: Disabled) Determines which
removable-media drives are supported by the SCSI controller BIOS. The options are as follows:
- Disabled— No removable media drives are treated as hard disk drives. Software drivers are then
required from the vendor, because the drives themselves are not controlled at all by the BIOS.
NOTE: You may lose data if you remove a removable-media cartridge from a SCSI drive con-
trolled by the SCSI controller 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 an
HDD
- All Disks—All removable media drives supported by the BIOS are treated as HDDs
- BIOS Support for Bootable CD-ROMs—(Default: Enabled) When set to Enabled the SCSI
controller BIOS allows the computer to boot from a CD-ROM drive.
- BIOS Support for Int 13 Extensions—(Default: Enabled) When set to Enabled, the SCSI
controller BIOS supports Int 13h extensions as required by Plug-and-Play. The setting can
be either enabled or disabled if your system is not Plug-and-Play
