Tom,

For the 2940 Adaptec you would press Ctrl A to enter the SCSI BIOS when the prompt to enter the BIOS appears on the screen.  If you turn off the SCSI BIOS you will also turn off the BIOS support for more than 2 drives, BIOS support for Bootable CD-Rom, and BIOS support for Int 13 which adds support for drives with more than 1024 cylinders (>504 Mbs).  Depending on the size of the drive this could be a problem, if the drive is larger than 504 Mbs then that is all that he will be able to access with the BIOS turned off..

The SCSI drive will need to be partitioned and formatted after the low level format to be accessed.
