PORT 80 CODES	The System BIOS passes control to the different buses at the following checkpoints to do
(CONTINUED)	various tasks:

	Code	Description

	2A	Initializing different bus system, static and output devices, if present.
	38	Initializing bus input, IPL and general devices, if present.
	39	Displaying bus initialization error message, if any.
	95	Initializing bus adapter ROMs from C8000H through D8000H.
ADDITIONAL BUS
ADDITIONAL BUS	While control is in the different bus routines, additional checkpoints are output to
CHECKPOINTS	Port 80H as word values to identify the routines being executed. These are word
	checkpoints. The low byte of the checkpoint is the system BIOS checkpoint where
	control is passed to the different bus routines, and the high byte indicates that the routine
	is being executed in different buses.
	The information included in the high byte of these checkpoints is detailed below:

	Bits	Description

	Bits 7-4	0000	Function 0.	Disable all devices on the bus.
		0001	Function 1.	Initialize static devices on the bus.
		0010	Function 2.	Initialize output devices on the bus.
		0011	Function 3.	Initialize input devices on the bus.
		0100	Function 4.	Initialize IPL devices on the bus.
		0101	Function 5.	Initialize general devices on the bus.
		0110 Function 6. Initialize error reporting for the bus.
		0111 Function 7. Initialize add-on ROMs for all buses.
