BIOS POST
At the system boot, BIOS should perform initial diagnostic test of hardware (CPU, Memory, PCI …etc). If "BIOS
Detected Error", BIOS stops the system. In any case, display an error message with POST Code. Some of the event will
be logged to BMC (e.g. CMOS checksum error, Memory ECC error, PCI error…), in any POST stop case, BMC will
timeout with a POST code event log.
BIOS stratagem is to stop the POST and display error message only when the error is detect by BIOS during POST. The
error detected by BMC or MMB during POST will handle and react by BMC or MMB, these errors are unaware for
BIOS, so BIOS will not stop the POST and not display error message to screen. For example CPU temp is monitored by
BMC to log the event, but no reaction by BMC, the CPU will do TM2 (Thermal Monitor 2) to reduce the CPU’s speed
and the temp, the worst case is, if CPU’s temp go more higher, the CPU’s Thermtrip output pin will assert to ICH10 and
make a system shut down by H/W (not by BMC). CPU’s voltage is also monitored by BMC with event log,
If error is detected, POST Code is displayed on Screen.
