The "boot from SCSI" BIOS option is a relatively modern invention. Once
upon a time, before this setting was available, systems could boot from
SCSI anyway, just not if there was an IDE device also in the system.
This was because every Wintel PC automatically pretends a SCSI HD is
an IDE HD if there is no IDE HD in the system, if the SCSI HBA has a BIOS.
Since the invention of the "boot from SCSI" BIOS option, not every BIOS
has been made smart enough to redirect a redirected SCSI HD back to 80
if the "boot from SCSI" option has been enabled. IOW, in some hardware
combinations, enabling "boot from SCSI" in the BIOS can prevent a SCSI
boot.
