The ide chip does not support 48 bit registers. To fix this in software
would so slow it would be unusable. The easiest solution is to get a cheap
pci ide card.

wd1 at pciide0 channel 0 drive 0: <WDC WD1800BB-00DAA0>
wd1: drive supports 16-sector PIO transfers, LBA48 addressing
wd1: 167 GB, 16383 cyl, 16 head, 63 sec, 512 bytes/sect x 351651888 sectors
wd1: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 5 (Ultra/100)
wd1(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 5 (Ultra/100) (using
DMA data transfers)

The drive needs to show up with "LBA48 addressing".

I was overlooked in the division of the spoil.
