"Beep Code Manual, Better Than Gold Techies, American Megatrends Int. & Phoenix (I’m IT, I use these codes to trouble shoot hardware issues at my job. Enjoy) cold.gif BIOS Beep Codes When a computer is first turned on, or rebooted, its BIOS performs a power-on self test (POST) to Because there are many brands of BIOS, there are no standard beep codes for every BIOS. The two most-used brands are AMI (American Megatrends International) and Phoenix. Below are listed the beep codes for AMI systems, and here are the beep codes for Phoenix systems. AMI Beep Codes Beep Code Meaning 1 beep DRAM refresh failure. There is a problem in the system memory or the motherboard. 2 beeps Memory parity error. The parity circuit is not working properly. 3 beeps Base 64K RAM failure. There is a problem with the first 64K of system memory. 4 beeps System timer not operational. There is problem with the timer(s) that control functions on 5 beeps Processor failure. The system CPU has failed. 6 beeps Gate A20/keyboard controller failure. The keyboard IC controller has failed, preventing ga 7 beeps Virtual mode exception error. 8 beeps Video memory error. The BIOS cannot write to the frame buffer memory on the video card. 9 beeps ROM checksum error. The BIOS ROM chip on the motherboard is likely faulty. 10 beeps CMOS checksum error. Something on the motherboard is causing an error when trying to inte 11 beeps Bad cache memory. An error in the level 2 cache memory. 1 long beep, 2 short Failure in the video system. 1 long beep, 3 short A failure has been detected in memory above 64K. 1 long beep, 8 short Display test failure. Continuous beeping A problem with the memory or video. BIOS Beep Codes Phoenix Beep Codes Phoenix uses sequences of beeps to indicate problems. The "-" between each number below indicates 4-Beep Codes Beep Code Meaning 1-1-1-3 Faulty CPU/motherboard.
