  1. I have tried to make this a comprehensive reference guide for all motherboards by borrowing info from various sources on the web. Feel free to shoot me a PM with updates or corrections.

    AMI BIOS Beep Codes:

    Beeps Error Message Description
    1 short DRAM refresh failure- The programmable interrupt timer or programmable interrupt controller has probably failed

    2 short Memory parity error- A memory parity error has occurred in the first 64K of RAM. The RAM IC is probably bad

    3 short Base 64K memory failure- A memory failure has occurred in the first 64K of RAM. The RAM IC is probably bad

    4 short System timer failure- The system clock/timer IC has failed or there is a memory error in the first bank of memory

    5 short Processor error- The system CPU has failed

    6 short Gate A20 failure- The keyboard controller IC has failed, which is not allowing Gate A20 to switch the processor to protected mode. Replace the keyboard controller

    7 short Virtual mode processor exception error- The CPU has generated an exception error because of a fault in the CPU or motherboard circuitry

    8 short Display memory read/write error- The system video adapter is missing or defective

    9 short ROM checksum error- The contents of the system BIOS ROM does not match the expected checksum value. The BIOS ROM is probably defective and should be replaced

    Phoenix ISA/MCA/EISA BIOS Beep Codes

    Phoenix ISA/MCA/EISA BIOS Beep Codes:
    The beep codes are represented in the number of beeps. E.g. 1-1-2 would mean 1 beep, a pause, 1 beep, a pause, and 2 beeps.
    With a Dell computer, a 1-2 beep code can also indicate that a bootable add-in card is installed but no boot device is attached. For example, in you insert a Promise Ultra-66 card but do not connect a hard drive to it, you will get the beep code. I verified this with a SIIG (crap -- avoid like the plague) Ultra-66 card, and then confirmed the results with Dell. Credit to John Palmer.

    MSI D-Bracket LED CODES

    Note- some motherboards do not give an AUDIO alert for BIOS beep/ hardware failures. LED light flashes can provide indication. If so, consult your motherboard manual. For example, MSI motherboards equipped with a D-bracket will show the following:

    *= lit
    0 = unlit

    **
    **
    System Power ON -The D-LED will hang here if the processor is damaged or not installed properly.

    0*
    **
    Early Chipset Initialization

    *0
    **
    Memory Detection Test- Testing onboard memory size. The D-LED will hang if the memory module is damaged or not installed properly

    00
    **
    Decompressing BIOS image to RAM for fast booting

    **
    0*
    Initializing Keyboard Controller

    0*
    0*
    Testing VGA BIOS- This will start writing VGA sign-on message to the screen

    *0
    0*
    Processor Initialization- This will show information regarding the processor (like brand name, system bus, etc...)
