Any of the rescue cd's for linux that can get you to a prompt should be 
able to do it, we do it all the time with dd and fill all the drive with 
zeros, 1 byte at a time. This will clear the entire drive, mbr and all. 
"dd bs=1k if=/dev/zero of=/dev/hda" , type that without the quotes. Also 
that assumes your wiping the first IDE drive on the first controller, if 
your not, adjust accordingly.
