How to check if a processor in the machine is dead

[Jayesh Jayan]

Hi,

I am having problem with my dell 2850 server. It has freebsd 5.4 installed.
Today the machine is flashing amber light on the face plate.On checking I
found that to be PROC Machine Chk which means cpu has failed.

The server has dual Intel(R) Xeon(TM) CPU 3.00GHz. I searched and found a
utility named x86info but couldn't understand the output much and also
couldn't get to know if a cpu has really failed.

Please help me in this regard.
