Look at the manufacturers website maybe they still have a bios update for
your mainboard, that allows for hd 's bigger than 32 Gb.
Or Look at the jumpersettings on your harddrive, sometime there's a
setting that limits your drive to 32Gb, that way you only loose 8Gb.
It's also possible to download "Drive Overlay Software" from some of
the manufacturers but i don't know if it works with Linux or win 2k, I
think the programs were made for win9x.
Good luck
