Promise Ultra100 and AK31/KT266 conflict

[Cherub]

I recently installed an AK31 motherboard, and noticed that the ATA/100 drives connected to my Promise Ultra100 card were being identified as PIO 4 drives, and naturally failed to boot. Now this is a BIOS issue, as the Promise has its own BIOS and recognizes drivers long before any drivers/etc. load. I have tried another Ultra100 with the same result.<BR><BR>The thing that really bugs me is thatmy Promise Ultra66 works perfectly in my AK31 (KT266), and the Promise Ultra100 works perfectly in my 8KTA3 (KT133A). This is why I blame the problem on a BIOS conflict.<BR><BR>Can anyone confirm this problem or offer a suggestion for solving it?

I have a Promise FastTrak100 TX2 RAID controller and it works fine on the AK31 (rev2). Not much help but I figured I'd add that to the mix.
