Code Description

The NMI is disabled. Next, checking for a soft reset or a power on condition.

The BIOS stack has been built. Next, disabling cache memory.

Uncompressing the POST code next.

Next, initializing the CPU and the CPU data area.

The CMOS checksum calculation is done next.

The CMOS checksum calculation is done. Initializing the CMOS status register for date and time next.

The CMOS status register is initialized. Next, performing any required initialization before the keyboard BAT command is issued.

The keyboard controller input buffer is free. Next, issuing the BAT command to the keyboard controller.

The keyboard controller BAT command result has been verified. Next, performing any necessary initialization after the keyboard controller BAT command test.

The initialization after the keyboard controller BAT command test is done. The key- board command byte is written next.

The keyboard controller command byte is written. Next, issuing the Pin 23 and 24 blocking and unblocking command.

Next, checking if <End or <Ins> keys were pressed during power on. Initializing CMOS RAM if the Initialize CMOS RAM in every boot AMIBIOS POST option was set in AMIBCP or the <End> key was pressed.

Next, disabling DMA controllers 1 and 2 and interrupt controllers 1 and 2.

The video display has been disabled. Port B has been initialized. Next, initializing the chipset.

The 8254 timer test will begin next.

Next, programming the flash ROM.

The memory refresh line is toggling. Checking the 15 second on/off time next.

Passing control to the video ROM to perform any required configuration before the video ROM test.

All necessary processing before passing control to the video ROM is done. Look- ing for the video ROM next and passing control to it.

The video ROM has returned control to BIOS POST. Performing any required pro- cessing after the video ROM had control

Reading the 8042 input port and disabling the MEGAKEY Green PC feature next. Making the BIOS code segment writable and performing any necessary configura- tion before initializing the interrupt vectors.

The configuration required before interrupt vector initialization has completed. In- terrupt vector initialization is about to begin.
