Summary: don't forget what diagnostics will do


One thing that bugs me about >1024 cylinder drives has not been
brought up.  Since hardware diagnostics (and several other sorts of
utilities) work through the BIOS, they will stomp on the last cylinder
of the drive as reported by the drive type.  If the drive type has a
limit of 1024, that's someplace mysterious towards the end of your
disk.  If the drive type has a limit greater than 1024, over the
10-bit limit of the BIOS, then it will wrap around to someplace
mysterious in the beginning of your disk, in your swap space if you
get lucky.
