Clearing the Battery-Backed RTC RAM

26.5.2

Using a GPI to Clear CMOS Registers

A jumper on a General-Purpose Input (GPI) pin is also used to clear the CMOS values.

The BIOS detects the setting of this GPI on system boot-up and manually clears the

CMOS array.

Note:

The GPI strap technique to clear the CMOS requires multiple steps to implement. The

system is booted with the jumper in the new position, then powered back down. The

jumper is replaced back to the normal position, then the system is rebooted again.

Warning:

Do not implement a jumper on VCCRTC_3P3 to clear the CMOS.
