Options: Yes and No. Send Start Unit Command: Specifies whether the channel will send a start unit command to the SCSI device. This option reduces the load on the power supply if enabled as the channel will turn on SCSI devices one-at-a-time. - Page 68 SCSI EP-BXBS Reset SCSI Bus at IC Initialization: If the SCSI BIOS is enabled, it will reset the SCSI bus when the computer is rebooted then scan for SCSI devices. This option specifies whether the BIOS will wait 2 seconds after the reset of the bus before scanning for SCSI devices.
