Things still missing from FDISK
-------------------------------

1) Boot code insertion untested.  Boot code also blatently stolen from
   an MS-DOS boot block - needs to be re-written.
2) Decides where to put a new partition table badly (always puts it at the end
   of the chain).
3) No error checking on partition start/end values.
4) All values are currently sector-based, rather than in Mbytes.
5) Needs to initiate a reboot (or at least tell the user to do so) on exit (if
   there have been any changes).
6) Check to make sure there aren't more partitions than it can display on
   one screen (and find some way to deal with it if there are).
7) Some form of help system (even if only what keys to press).

Things that need to be checked
------------------------------

1) What happens if there aren't any partitions already defined (ie. new disc).
2) Colour scheme (I've only seen it in mono VGA).
3) Operation on multiple drives.
4) Not sure if offset values are calculated correctly.
