BIOS Beep Codes - Quote :
- Some number of short beeps that are sounded by the BIOS upon startup when a memory, cache or processor error is encountered. There are numerous beep code patterns, and Phoenix BIOS codes are long and short beeps delivered in groups.
AMI BIOS Beep Codes:1 Short = DRAM refresh failure
- Quote :
- The programmable interrupt timer or programmable interrupt controller has probably failed
2 short = Memory parity error
- Quote :
- A memory parity error has occurred in the first 64K of RAM. The RAM IC is probably bad
3 short = Base 64K memory failure
- Quote :
- A memory failure has occurred in the first 64K of RAM. The RAM IC is probably bad
4 short = System timer failure
- Quote :
- The system clock/timer IC has failed or there is a memory error in the first bank of memory
5 short = Processor error
- Quote :
- The system CPU has failed
6 short = Gate A20 failure
- Quote :
- 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
- Quote :
- The CPU has generated an exception error because of a fault in the CPU or motherboard circuitry
8 short = Display memory read/write error
- Quote :
- The system video adapter is missing or defective
9 short = ROM checksum error
- Quote :
- 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
- Quote :
- The shutdown for the CMOS has failed
11 short = Cache error
- Quote :
- The L2 cache is faulty
1 long, 2 short = Failure in video system
- Quote :
- An error was encountered in the video BIOS ROM, or a horizontal retrace failure has been encountered
1 long, 3 short = Memory test failure
- Quote :
- A fault has been detected in memory above 64KB
1 long, 8 short = Display test failure
- Quote :
- The video adapter is either missing or defective
2 short = POST Failure
- Quote :
- One of the hardware testa have failed
.
1 long = POST has passed all tests
