The maximum allowable values for each field of type 47 will tell you how
much of the 20GB drive the BIOS of the machine can support. If the
number turns out to be small (like only 540MB) and you need more
capacity, disable the onboard controller and get a replacement
controller that has a replacement BIOS. Promise made quite a few of
these, to name one manufacturer.
If you can't do that, go for the drive overlay software.
Your chances on booting from CD using the BIOS on a 486 are slim and
none. Even SCSI cards of the era with their own BIOS don't do that. So
plan on getting a 3.5" floppy for it.
