Probably a BIOS limitation. Many (even current) BIOS don't support that
large of an HD. This applies to any OS that you use on it. It has to
do with the number of bits allocated to address the drive. 2^28*512.
Some older articles on the issue -
"The current ATA interface uses 28 bit addressing which supports drives
that are 2^28 X 512 bytes or 137 GB"
