Perry,

Its even worse. On one mtbd; the BIOS had a menu 
for enabling ECC; I did. But reading the register 
from the chipset revealed nothing was actually 
enabled in the hardware. You have to be paranoid 
in this business. This was a "bleeding edge" 
mtbd, with a low revision BIOS of course. The fu 
being that a car manufacturer ran a cluster of 
these for several months doing crash worthiness simulations ...
