Yes (?) though AFAICT it is only used when you disklabel and newfs it
in the first place. Once it's up and running, I don't think that entry
ever gets used again. (Useful to keep a copy though as it is
equivalent to the disklabel for the sad day the disk crashes)

Yes, where name of drive is the single word you called it as the first
part of its entry in the disktab.

The big question is, do you want to use the disk with DOS as well? In
which case the bios needs a lookin and it can't cope with 2220 > 1024
cylinders, or for that matter 76 > 32 sectors => the thing to do in that
case is to pretend that your drive is in fact
(2220 * 4 * 76)/(32 sectors/track * 64 tracks/cylinder)=329 cylinders,
and tell absolutely everything that you have 329 cylinders, 32
sectors/track, 64 tracks/cylinder = 673792 sectors (you really have
674880 sectors). I suppose you could come up with yet another
geometry. I found that was what my SCSI card came up with as a
default.

Good luck,
