Yeah, but there's a flip side to this too: if no one uses the data, no one will complain when it's wrong. If Linux starts making it easy to see this stuff, there's a chance system vendors will start taking an extra 5 min. before shipment to make sure that the BIOS info is up to date... OTOH, I'm not sure which is worse, bad data or no data. Jesse
