if permitted by the SCSI controller. When set to No, the SCSI device is not allowed to disconnect from the SCSI bus. The default setting
is Yes.
Keep this item set to Yes if two or more SCSI devices are connected to the SCSI controller. This can optimize SCSI bus performance. If
only one SCSI device is connected to the SCSI controller, set this item to No to achieve better system performance.
4.3.7.5 Send Start Unit Command
This option determines whether the Start Unit Command (SCSI command 1B) is sent to the SCSI device (most devices do not require
this). Enabling this item reduces the load on the system power supply by allowing the SCSI controller to power up SCSI devices one at
a time upon booting. Otherwise, all the devices power up at the same time. Most devices require you to set a jumper before they can
respond to this command.
When set to Yes, the Start Unit Command is sent to the SCSI device at system boot. When set to No, each SCSI device powers up in
the normal procedure.
The Send Start Unit Command setting is valid only if the
host adapter BIOS is enabled.
If this option is enabled for more than one SCSI device, the Start Unit Command is sent first to the device with the lowest SCSI ID.
When this device responds to the SCSI controller, the Start Unit Command is sent to the next highest SCSI ID with a setting of Yes. The
process continues until all supported devices respond to the SCSI controller.
If many drives are set to Yes for Send Start Unit Command, the boot time varies depending on how long it takes each drive to spin up.
