The following settings are only effective if the BIOS is enabled.
•
Send Start Unit Command
– The setting for this option, which is supported
by some SCSI devices, determines whether the channel sends the Start Unit
command (SCSI command 1B) to the SCSI device (most devices do not
require this). Enabling this option reduces the load on your computer’s
power supply by allowing the channel to turn on SCSI devices one-at-a-time
when the computer boots. Otherwise, all SCSI devices turn on at the same
time. Most devices require you to set a jumper before they can respond to
this command.
When set to Yes, the channel sends the Start Unit command to the SCSI
device during bootup. When set to No, each SCSI device powers up when
the computer powers up. The default setting is No.
•
BIOS Multiple LUN Support
– The setting for this option determines
whether booting from a SCSI device that has multiple LUNs is supported.
The default setting is Disabled.
BIOS Multiple LUN Support must be enabled
in order to use the Boot LUN Number during
bootup.
•
Include in BIOS Scan
– This setting gives the AIC-7896 the ability to ignore
any SCSI devices attached to the SCSI bus during bootup. The AIC-7896
BIOS scans a specific SCSI ID looking for a stand-alone disk device to control.
If Include in BIOS Scan is set to Yes for a SCSI ID the BIOS scans the ID, and
the disk device at that ID becomes accessible through Int 13h; if the option is
set to No, the BIOS does not scan the SCSI ID. The default setting for Include
in BIOS Scan is Yes.
