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
10 short CMOS shutdown register read/write error- The shutdown for the CMOS has failed
11 short Cache error- The L2 cache is faulty
1 long, 2 short Failure in video system- An error was encountered in the video BIOS ROM, or a horizontal retrace failure has been encountered
1 long, 3 short Memory test failure- A fault has been detected in memory above 64KB
1 long, 8 short Display test failure-The video adapter is either missing or defective
2 short POST [Power On Self Test] Failure- One of the hardware tests have failed. Frequently caused by failed ram, but not always.
1 long POST [Power On Self Test]- has passed all tests
For Motherboards with AWARD BIOS
Beeps Error Message Description
1long, 2 short Video adapter error- Either video adapter is bad or is not seated properly. Also, check to ensure the monitor cable is connected properly.
Repeating (endless loop) Memory error- Check for improperly seated or missing memory.
1long, 3short No video card or bad video RAM- Reseat or replace the video card.
High frequency beeps while running Overheated CPU- Check the CPU fan for proper operation. Check the case for proper air flow.
Repeating High/Low CPU failure- Either the CPU is not seated properly or the CPU is damaged. May also be due to excess heat. Check the CPU fan or BIOS settings for proper fan speed.
I've included the two most popular codes.. If your running something a little rarer like say a compaq then check out the full list here: The complete BIOS beep guide - TechSpot OpenBoards
