I wouldn't be caught dead reflashing the firmware to get rid of an
instrumentation error. I'd rather live with the error.

When you reflash, you run a not insignificant risk of bricking your
mobo, which, for practical purposes, often means you're cheaper
off replacing the RAM and CPU too. It's much safer if you're on a UPS,
but still, do one thing wrong, and you're bricked.

I'd be willing to turn off and unplug the machine, and remove the coin
battery for a night, to see if something resets. But I'd need a much
better reason than fixing a harmless instrumentation error to reflash a
bios, and I'd *certainly* not do it on a "maybe this will fix it" basis.
