subject: disk geometry revisited

I happened to take notice last night of this floppy laying here on my desk
that mentioned something about Norton's Diskedit program,  so I thought I'd
fire it up,  and it was indeed as I remembered it to some extent.

Did a search for the partition table sig bytes of 55AA,  and I found a
*bunch* of instances of it,  in most if not all cases at the end of a
sector,  a fact I found interesting since I don't remember prior setups on
that particular physical drive.

I just need to figure out now how disk geometry can be re-interpreted to
point to one of those places -- I've found a couple of good candidates for
what should be the start of that HPFS partition that the system doesn't
seem to see at present,  where in the sector preceding the sig I can see
"OS2" and "HPFS" and "OS2KRNL" and
"OS2LDR" and the volume label used in boot manager,  "OS2
Boot".

Cylinder 11,  side 1,  sector 1,  absolute sector 176,778.
