12h Use walking 1's algorithm to check out interface in CMOS circuitry. Also set real-time clock power
status, and then check for override.
13h Reserved
14h Program chipset default values into chipset. Chipset default values are MODBINable by OEM
customers.
15h Reserved
16h Initial Early_Init_Onboard_Generator switch
17h Reserved
18h Detect CPU information including brand, SMU type (Cyrix or Intel) and CPU level (586 or 686)
19h Reserved
1Ah Reserved
1Bh Initial interrupts vector table. If no special specifi ed, all H/W interrupts are directed to SPURI-
OUS_INT_HDLR & S/W interrupts to SPURIOUS_softHDLR.
1Ch Reserved
1Dh Initial EARLY_PMI_INIT switch
1Eh Reserved
1Fh Load keyboard matrix (notebook platform)
20h Reserved
21h HPM initialization
22h Reserved
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 and 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 and I/O resource
- Search for a valid VGA device and VGA BIOS and put it into C000:0.

27h Initialize INT 09 buffer
28h Reserved
29h 1. Program CPU internal MTRR (P6 & PII) for 0-64K memory address.
2. Initialize the APIC for Pentium class CPU.
3. Program early chipset according to CMOS setup. Example: onboard IDE controller.
4. Measure CPU speed.
5. Invoke video BIOS.
