6.4.10.4 BIOS Push Button Enable Register
The BIOS writes to this register to enable the front panel push button reset, the RTM push
button reset, the IPMC reset, and the PCH_WDT_TOUT_ reset.
6.4.10.5 OS Reset Source Register
The OS Reset Source Register stores the source of the most recent reset. It is similar to the BIOS
Reset Source Register. 1 in the register bit indicates that the associated reset has occurred. If
more than one reset occurs from different sources without clearing the corresponding register
bits, one cannot determine the most recent reset source since more than one bit will be set.
This occurs if two reset sources go active at the same time.
After a timeout of 8s the resets are armed again.
