Code Explanation

X X X

D8 D3 D2 D1

Initialization of the chipset. The MCH and ICH registers will be set to the most

conservative values by the BIOS to make sure the system boots up properly.

X X LX

D8 D3 D2 D1

The BIOS is now decompressing the BIOS code into shadow RAM. Most of

the BIOS code is stored in the BIOS Flash ROM IC in compressed form to

save space. At boot-up this code is decompressed and stored to RAM for faster

execution.

X X L L

D8 D3 D2 D1

The checksum for the decompressed code is calculated and checked. The

checksum is calculated by adding all data bytes together and storing the result

in the BIOS ROM. If the calculated checksum is different from the checksum

stored in the ROM, the code stored in the FLASH ROM is corrupted.

XLX X

D8 D3 D2 D1

The chipset (MCH and ICH) registers are set to the values selected by the user.

XLXL

D8 D3 D2 D1

Now the BIOS will set the CPU Vcore voltage and the FSB bus frequency to

the user selected value. If the system stops at this point, the settings selected by

the user are inappropriate. Please select more conservative settings.

XL L X

D8 D3 D2 D1

The Hardware Monitor Functionality is initialized. The settings the user

selected in the BIOS for the Hardware Monitor are written into the Hardware

Monitor registers.

XLLL

D8 D3 D2 D1 If the VGA card does not work or is not inserted at all, the system will display

this code for a short period of time.

LXXX

D8 D3 D2 D1

At this point the BIOS is initializing the CPU. The L2 cache latency values are

set, and more important, the CPU micro-code is written into the CPU.

LX X L

D8 D3 D2 D1

Now the system is testing the RAM inserted on the board. The screen will

show the BIOS testing the RAM by a running counter. After finishing the test,

the screen will show the amount of RAM in your system.

LXLX

D8 D3 D2 D1 The super I/O registers are set to the default values. This includes the serial,

parallel and IR etc settings.

LXL L

D8 D3 D2 D1

At this point the IDE busses (primary and secondary) are scanned for devices.

This includes HD drives and ATAPI CD-ROM drives that are connected to the

IDE bus. After scanning the detected devices are displayed on screen.

L L X X

D8 D3 D2 D1 The serial and parallel port registers are set to the values selected by the user.

L L XL

D8 D3 D2 D1

Now the BIOS will scan the peripheral busses for add-on cards. This includes

the PCI and AGP busses. If any add-on cards are detected, the resources it

requires are assigned by the BIOS in accordance with user settings.

L L L X

D8 D3 D2 D1

The ESCD and DMI (Desktop Management Interface) values are checked. If

there are changes, the BIOS will flash the new values into the BIOS Flash

ROM IC.

L L L L

D8 D3 D2 D1

At this point the BIOS passes control to the Operating System (OS). All LEDs

will be on and will stay on to indicate a successful boot.
