Chapter 8: Configuring the Adaptec SCSI Card with SCSISelect ● 39 ● Disabled:Scan Bus-Set to this option if all the devices on the SCSI bus (for example, CD-ROM drives) are controlled by software drivers and you need the BIOS to scan the SCSI bus. Allows devices to spin up 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. If you change this setting, the change automatically applies to both SCSI channels. ● 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 disk drives. Software drivers are required because the drives are not controlled by the BIOS. ! Caution: 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 disk drive. ● All Disks-All removable-media drives supported by the BIOS are treated as disk drives. This setting has no effect on drives under NetWare because NetWare automatically supports removable-media drives as disk drives. Note: The Boot Only and All Disks options are available only if the SCSI card BIOS option is 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 disk or other device, make sure no bootable CD is inserted, or disable this option. Changing Configuration Settings The factory default settings for Adaptec SCSI cards are correct for most computers. However, if you need to change the settings for the SCSI card or a SCSI device: 1 If you have not yet installed the SCSI card and the SCSI devices, do so now. Refer to your SCSI card Installation Guide for details. 2 Start SCSISelect. See Starting SCSISelect on page 36. SCSISelect detects all Adaptec SCSI cards and displays the model number, channel letter, slot number, and PCI address for each card and channel. Channels are listed separately. 3 Select the 29320LPE, then press Enter.

Disabled:Scan Bus
—Set to this option if all the devices on the SCSI bus (for example,
CD-ROM drives) are controlled by software drivers and you need the BIOS to scan the
SCSI bus. Allows devices to spin up according to the setting of the Send Start Unit
Command. SCSI
Select
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. If you change this setting, the change automatically applies to both SCSI
channels.
●
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 disk drives.
Software drivers are required because the drives are not controlled by the BIOS.
Caution:
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 disk drive.
●
All Disks
—All removable-media drives supported by the BIOS are treated as disk
drives. This setting has no effect on drives under NetWare because NetWare
automatically supports removable-media drives as disk drives.
Note:
The Boot Only and All Disks options are available only if the SCSI card BIOS option is
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 disk or
other device, make sure no bootable CD is inserted, or disable this option.
