The chipset is an AMD-8131 and the board details are at:
http://www.msicomputer.com/product/p_spec.asp?model=K8D_Master-F
I did the following boot tests:
2.6.8-1.533 "mem=3950M" ==> OK
2.6.8-1.533 "mem=12G" ==> causes immediate re-boot
early in the boot stage (too fast to read)
2.6.8-1.533 wo/ any "mem=" ==> same immediate re-boot problem
And then I tried re-seated the RAM and now it won't POST. Rats! This
is disappointing.
