The hardware list known to working or non-working is below.

Since the document is dated, the recent releases should
support more hardware than that of above.  You want to
select DP8390 based card, not 68000 based one.

Internal disk is convenient for moving the box:-)

If you use external drive, use shorter (and harder, which
indicates good shielding) SCSI cable for reliable signal
transfer.
