Initialize first 120 interrupt vectors with SPURIOUS_INT_HDLR
and initialize
INT 00h-1Fh according to INT_TBL
CMOS RAM Test CMOS RAM Checksum, if bad, or insert key pressed, load
defaults.
Detect type of keyboard controller (optional)
Set NUM_LOCK status.
Video Detect CPU clock.
Read CMOS location 14h to find out type of video in use.
Detect and Initialize Video Adapter.
Test video memory, write sign-on message to screen.
Setup shadow RAM - Enable shadow according to Setup.
BIOS checksum test.
Keyboard detect and initialization
DMA Page Test DMA Page Registers.
Test 8254 Timer 0 Counter 2.
Verify 8259 Channel 1 masked interrupts by alternately turning off
and on the interrupt lines.
Verify 8259 Channel 2 masked interrupts by alternately turning off
and on the interrupt lines.
Stuck 8259's Turn off interrupts then verify no interrupt mask register is on.
8259 Interrupt Force an interrupt and verify the interrupt occurred.
Verify NMI can be cleared.
Display CPU clock
If EISA non-volatile memory checksum is good, execute EISA
initialization. If not, execute ISA tests an clear EISA mode flag.
Test EISA Configuration Memory Integrity (checksum &
communication interface).
Initialize slot 0 (System Board).
Initialize slots 1 through 15.
Size base memory from 256K to 640K and extended memory
above 1MB.
Test base memory from 256K to 640K and extended memory
above 1MB using various patterns.
NOTE: This will be skipped in EISA mode and can be "skipped"
with ESC key in ISA mode.
Extended If EISA Mode flag is set then test EISA memory found in slots
initialization.
NOTE: This will be skipped in ISA mode and can be "skipped"
with ESC key in EISA mode.
