I have seen this once before. What I found out is that these errors will occur with XP and an older BIOS. Something to do with the way a bios is programmed. The Shuttle ak12 is a older motherboard and has been discontinued. This last BIOS they have for it is from June 2001 and I doubt they are going to release an update for it. You can ensure you BIOS is the latest version but beyond that the best I can say for now is that if you are noticing no problems with your system then just ignore these errors.--------------------------------------------------------------------------------
XP logs the slightest error it finds, 99.9% of the time it doesnt affect anything. Just ignore it Jon, unless it starts crashing or not doing something it should
