Okay, I am really pissed right now. I just got an MSI 694D Pro dual cpu board with the Promise ATA100 controller. I'm really confused about it, because the Promise chip itself says PCD20265 but it has a FastTrack BIOS screen and menu after the mobo BIOS. I have tried several different drivers from both MSI's website and Promise's site, and the driver off the CD-rom. I also tried to install the driver of the same chip (supposedly) PCD20256 off my Asus A7V mobo.
No matter what, it still shows a conflict with the controller. I cannot seem to get a hold of the correct driver, so if someone could point me to the right one, it would be greatly apprciated.

Motherboard MSI 694D Pro AR (I think). MSI has been no help.

Never mind...even though my board is a 694D Pro-A, I had to get drivers for the Pro-AR. Makes me think they mislabeled the box.
Runs great.;)
