Obviously I need a BIOS - I do want to be able to boot my nice new
machine... Unless it's ultrawide SCSI, I'd be faster with IDE anyway, so
include that.
The IDE cost is 0; the SCSI cost is up to 120 DM? SCSI isn't looking too
good so far...

Perhaps; having said that, you can use SCSI drivers with an IDE drive :-)

SCSI just can't compete here, yet.
