2-18			Chapter 2
		1.	Disable PS/2 mouse interface (optional)
	0A	2.	Auto detect ports for keyboard & mouse followed by a port & interface swap (optional)
		3.	Reset keyboard for Winbond 977 series Super I/O chips
	0E	Test F000h segment shadow to see whether it is R/W-able or not. If test fails, keep
		beeping the speaker
	10	Auto detect flash type to load appropriate flash R/W codes into the run time area in F000
		for ESCD & DMI support
	12	Use walking 1’s algorithm to check out interface in CMOS circuitry. Also set real-time
		clock power status, and then check for override
	14	Program chipset default values into chipset. Chipset default values are MODBINable by
		OEM customers
	16	Initial Early_Init_Onboard_Generator switch
	18	Detect CPU information including brand, SMI type (Cyrix or Intel) and CPU level (586
		or 686)
	1B	Initial interrupts vector table. If no special specified, all H/W interrupts are directed to
		SPURIOUS_INT_HDLR & S/W interrupts to SPURIOUS_soft_HDLR
	1D	Initial EARLY_PM_INIT switch
	1F	Load keyboard matrix (notebook platform)
	21	HPM initialization (notebook platform)
		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
	23	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
			-Search for a valid VGA device & VGA BIOS, and put it into C000:0
	27	Initialize INT 09 buffer
		1.	Program CPU internal MTRR (P6 & PII) for 0~640K memory address
		2.	Initialize the APIC for Pentium class CPU
	29	3.	Program early chipset according to CMOS setup. Example: onboard IDE controller
		4.	Measure CPU speed
		5.	Invoke video BIOS
	2D	1.	Initialize multi-language
		2.	Put information on screen display, including Award title, CPU type, CPU speed …
	33	Reset keyboard except Winbond 977 series Super I/O chips
	3C	Test 8254
	3E	Test 8259 interrupt mask bits for channel 1
	40	Test 8259 interrupt mask bits for channel 2
	43	Test 8259 functionality
	47	Initialize EISA slot
	49	1.	Calculate total memory by testing the last double word of each 64K page
		2.	Program writes allocation for AMD K5 CPU
