Well... this is an old Apollo WD7000 controller, actually WD7000xx, don't
offhand remember what the letters were after it.. OEM version for Apollo with
a 68K PROM on it instead of x86.... its actually a combo FDC/ESDI-HDC/SCSI
card. Under the Apollo's, the disk was formatted to 1K sectors, which isn't
so good for NetBSD. I'm looking to see if I can format just a part of the
drive as 1K sectors (Apollo-style filesystem to boot from) and find a way to
partition/format the rest as 512-byte sectors. Ought to be an interesting
challenge...
I actually found a format utility in source, in 'c', for WD style
controllers... I'll have to play with it and see what I can do.
