Ah, and I was trying to have os9 start AFTER HDB-DOS.  I'll blame
working late into the night for why it didn't occur to me that, if
NitrOS-9 was at the end of the drive, the offset shouldn't be such a
large number.

I'm still not sure what to set the sectors per track at; the drive
specs say "AVERAGE SECTORS PER TRACK = 107 rounded down".

Guess I'd better shrink that 3.9 Gigabyte os9 partition a bit ;)
