I have a KT133A motherboard, which supported UDMA 100. But I am unable to
run it at UDMA100. The IDE controller is always UDMA mode (UDMA33). I have
follow the instruction from Microsoft to add UDMA 66 registry, but it does
not help.

How can I set the IDE interface to UDMA100?

Uhm, you do use an 80 conductor cable, don't you?

Mr Obvious,

Install VIA IDE driver is one of the chooses.
However, the Windows 2000 + sp3 should be able to run UDMA100. Why it can't?
