I have two BE6's and I can't find anything in the BIOS that has anything to do with disabling the ATA66 controller. Abit tech support told me that I couldn't.
However, after looking through newsgroups for an answer, I found the following instructions for removing the ATA66 from your BIOS by modifying the .bin file and then flashing the BIOS. I haven't tried it yet, but I hope it works. I am planning on doing this soon.
