Well, thanks for looking at it; if there are any more patches I can try,
let me know (but I may not get to it until Monday morning, since I can't

Is this a BIOS error? I am currently running A04; there's an A10
available, but I didn't want to perturb the situation during the
debugging cycle without guidance.
