Question
I have a system, 5086B-TRF(X8OBN-F), and use Westmere-EX CPU. I saw the system hanging at POST code 99. What does this mean? I am using RHEL 5.4 x86_64 OS.

Answer
With Westmere-EX CPU in 5086B-TRF, you will have to change APIC mode from Auto to Compatible APIC inside BIOS if RHEL 5.4 is used. RHEL 5.4 does not support X2APIC.
