Description of check-point
detect type of keyboard controller
(optional). Set num_lock status.
Detect CPU clock. Read interface
CMOS location 14h to find out type
of video in use. Detect and initialize
video adaptor.
Test video memory, write sign-on
message to screen. Set up shadow
RAM-enable according to setup.
BIOS checksum test. Keyboard
detection and initialization.
Test DMA page registers.
Reserved
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
functionalityinterrupt occurred.
Verify NMI can be cleared.
Initialize slot 0 (system board).
Initialize slots 1 through 15.
Size base memory from 256 KB to
640 KB and extended memory
above 1MB.
Test base memory from 256 KB to
640 KB and extended memory
above 1 MB using various patterns.
Note: this will be skipped in EISA
mode and can be "skipped" with
ESC key in EISA mode.
