For what it's worth:
I successfully installed IBM 12GN(12GB) on Mitsubishi Amity CN2.
Notebook has only UDMA33. Works just fine.
Although had some BAD lockup in BIOS, when trying to tell
BIOS to use DMA3. Had to disconnect the drive, restart, then
again to connect and only then to change BIOS. BR-rrrrr.
Fortunately it does not really matter how BIOS talks to HD.
Because even w95 does not use it.
