Use walking 1’s algorithm to check out interface in CMOS
circuitry.
Also set real-time clock power status, and then check for
override.

23h 1. Check validity of RTC value:
e.g. a value of 5Ah is an invalid value for RTC minute.
2. Load CMOS settings into BIOS stack. If CMOS checksum
fails, use default value instead.
3. Prepare BIOS resource map for PCI & PnP use. If ESCD
is valid, take into consideration of the ESCD’s legacy
information.
4. Onboard clock generator initialization. Disable respective
clock resource to empty PCI & DIMM slots.
