Well, I have the exact same Hi-Tech USA ISA-486/33 system, with 1542B and
SCSI disk, and it works fine. Hint: The partition layout is critical! If
you've left a DOS partition before the Unix "a" partition, you have to
patch "asboot" to point to where the Unix "a" partition really is -- else
"asboot" thinks it's at "0". (This is a bug in "asboot".)
