[rescue] 501-5365 in E3000 causes "Overtemp detected on board 16" during POST

[Jonathan Katz]

Ugh. Not sure of a silver-bullet answer. The x500 boards should work
in x000 and vice-versa, just at the lower backplane clock speed (50Mhz
vs. 83Mhz, IIRC.)

E3x00 don't have a board 16 (right?) so I'm not sure where it would
get the temp from. Almost sounds like a resistor or surface-mount
capacitor broke off and it's confused, thinking it's in an E6500 or
something. Any bent pins anywhere?
