PC Setup
When using SCSI in a PC, the most common method is to run your SETUP program and define "No Drives Present". The SCSI Host Adapter will automatically self-configure on power-up. To install the drive, follow the manufacturer's instructions to use the on-board BIOS routine or software that was supplied with the Host Adapter.
