Hmm, I just fired up the HTPC and while it appears to work okay, it still says that the BIOS version is 7.2.2, which doesn't match any of the versions listed on the Asus download page. I thought that I had ordered an updated chip for this motherboard, but it must have only been for the A8N-SLI that I'm replacing.
I got a response for a question that I sent to the BIOS Depot, which I used previously, and they say that they program the chips to version 1409, and claim that they have never had a problem with it, so I think I'm going to order one.
