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.

 

5.

Early PCI initialization:

 

 

-Enumerate PCI bus number

 

 

-Assign memory & I/O resource
