10 Test DMA Controller 1

11	Test DMA Page	Test DMA page registers.
	Registers
12–13	Reserved
14	Test Timer Counter 2	Test 8254 Timer 0 Counter 2.
15	Test 8259-1 Mask Bits	Verify 8259 Channel 1 masked interrupts by alternately
		turning the interrupt lines off and on.
16	Test 8259-2 Mask Bits	Verify 8259 Channel 2 masked interrupts by alternately
		turning the interrupt lines off and on.
17	Test Stuck 8259’s	Turn off interrupts, then verify no interrupts mask register is
	Interrupt Bits	on.
18	Test 8259 Interrupt	Force an interrupt and verify that the interrupt occurred.
	Functionality
19	Test Stuck NMI Bits	Verify NMI can be cleared.
	(Parity/IO Check)
1A	Display CPU clock
1B–1E	Reserved
1F	Set EISA Mode	If EISA nonvolatile memory checksum is good, execute
		EISA initialization. If not, execute ISA tests and clear EISA
		mode flag. Test EISA Configuration Memory Integrity
		(checksum and communication interface).
20	Enable Slot 0	Initialize slot 0 on the system board.
21–2F	Enable Slots 1-15	Initialize slots 1 through 15 on the system board.
30	Size Base and	Size base memory from 256K to 640K and extended
	Extended Memory	memory above 1MB.
31	Test Base and ExtendedTest base memory from 256K to 640K and extended
	Memory	memory above 1MB using various patterns. Note: This will
		be skipped in EISA mode and can be skipped with the ESC
		key in ISA mode.
32	Test EISA Extended	If EISA Mode flag is set, then test EISA memory found in
	Memory	slots initialization. Note: This will be skipped in ISA mode
		and can be skipped with the ESC key in EISA mode.
33–3B	Reserved
3C	Setup Enabled
3D	Initialize and Install	Detect if mouse is present, initialize mouse, install interrupt
	Mouse	vectors.
3E	Set Up Cache ControllerInitialize cache controller.
3F	Reserved
BF	Chipset Initialization	Program chipset registers with Setup values.
40		Display virus protect disable or enable
41	Initialize Floppy Drive	Initialize floppy disk drive controller and any floppy drives.
