I don't think you can boot your computer from the SCSI disk
with the presents of your IDE (disabled in the BIOS setup).

With the presents of an IDE controller, your SCSI controller
recognizes itself as a secondary controller.  Disabling 
the IDE drive from your BIOS means you don't have a bootable
hard drive [drive C:].

If you want to physically disable your IDE drive, you should
open your computer and disable your IDE controller completely,
and then disable your IDE drive from the BIOS setup.
