| 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
