using an ASUS P8P67 WS REVOLUTION and I get the diagnostic code "A0" which is not in the manual.

Will someone tell me what it means?

Turns out "A0" is a drive error. Since I was breadboarding the mobo, no drives were connected and the result was this code.

Dear Asus: please update your manuals to include the description of all diagnostic codes.

IIRC, 'A0' actually means that control has been handed over to the boot device... I've seen this when I had the GP Diag card connected. So it *technically* isn't an error. I do agree that Asus should document these codes, but I think they need to get that info from AMI.

In my case, I was bread boarding the system without the HDD connected. The 'A0' just showed that no boot device was detected.

I have a different mobo, but I don't think that you need to worry about it.

If you want to be absolutely sure, give the Asus customer service guys a call. That's what I ended up doing just to be sure.
