DOS or the BIOS has a limitation where it can't handle anything > 1023
cylinders, so there's often something in the boot sector fiddles the
numbers. e.g. with a 1200 cylinder 8 head drive, the BIOS pretends
it's 600 and 16 to get around that limitation. Linux on large drives
needs to have this nonsense overridden or it gets very confused.
Sounds to me like Plan 9 & the DOS number-fiddling software don't
like each other & Plan 9 is only seeing half the cylinders.
