Reset Jumper PCH RTC Core (P-RTC)
The jumper P-RTC is used to reset the battery backed core of the PCH. This effects some registers
within the PCHs RTC core that are important before the CPU starts its work after a system reset. Note
that P-RTC will neither set UEFI BIOS Setup to EKF Factory Defaults nor resets the real time clock. To
reset the RTC core the board must be removed from the system rack. Short-circuit the pins of P-RTC
for about 1 sec. After that reinstall the board to the system and switch on the power. It is important
to accomplish the RTC reset while the board has no power.
