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.
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.
Turn off interrupts then verify no interrupt mask register is on.
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 and 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 256KB to 640KB and extended memory above
1 MB.
Test base memory from 256KB to 640KB and extended memory above
1 MB using various patterns.
NOTE: This will be skipped in ISA mode and can be « skipped » with
ESC key in EISA mode.
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.
Detect if mouse is present, initialize mouse, install interrupt vectors.
Initialize Cache controller.
Program chipset registers with Setup values.
Display virus protect disable or enable
Initialize floppy disk drive controller and any drives.
Initialize hard drive controller and any drives.
Initialize any serial and parallel ports (also game port).
Initialize math coprocessor
