Please, do some research (googling) before asking
such questions, as they usually require much more

Your motherboard has VIA P4M266A chipset, carrying
VT8233A on board. Ata(4) driver is not completely new
in 6.0, and it has supported this very IDE controller for
some time already. Please consult your motherboard's
manual (I can't download it as all Asus sites behave very
badly) and disable all non-standard options, you can try
some thing like "Load safe defaults" or "Load optimized

BTW, this question belongs to questions@, so cc there.
