I found the solution for my mediacheck fail problems with FC3. At the boot prompt type: linux ide=nodma I think I've burned twenty-five disks and run md5sum at least fifty times. Thanks to everybody that tried to help. There is a lot of contradictory information out there. None of the nocddma answers worked for me. It is possible that they work for somebody with some problem but not mine. Anyway, now to try to install it :-). -- Knute Johnson Molon Labe...
