Open 
A 
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.
