Relax IDE CHS limits from 16383,16,63 to 65535,16,255
New limits straight from ATA4 6.2 Register delivered data transfer
command sector addressing.
I figure the old sector limit 63 was blindly copied from the BIOS
int 13 limit. Doesn't apply to the hardware. No idea where the old
cylinder limit comes from.
