There's also no reason *to* use the natural Buslogic >1GB mapping. If he
doesn't want to use DOS (which is the natural assumption here) and he
doesn't plan on booting from the disk (also assumed), then there is
absolutely no reason not to make up the numbers. This is all in the
SCSI-HOWTO.

No need whatsoever to upgrade. What really has to be done is for fdisk
to not require h/c/s numbers.
