That's a good one! Operator addendum: plz eject disk and quickly insert again... I have an old laptop with some dev tools on it that also runs XP. I use it lightly and it has a bad fan. Set to entirely passive cooling? Nope. BIOS wants to see the fan spin, so... Sitting near that laptop is one of those computer air cans. At power on, wait about a second, shoot fan with air, BIOS sees spin, system check passes and just don't run the machine past passive cooling limits.
