I have the same issue. If onboard audio is disabled my board will not complete POST. Has anyone found a work around (besides leaving it on)?
I had the same problem with the newest BIOS version 094 if I wanted to disable onboard audio.You can take BIOS version 085 and everything is working fine.
Thanks for the reply. Unfortunately when my board went non responsive last time, it would not recover with 085 version, and would only accept a rev 094 recovery. I think I'm stuck with this board until I replace it with something better, hopefully.
