Default BIOS Beep Codes List


Beep Codes for the two most used brands AMI systems and Phoenix systems

AMI Beep Codes
  • 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 the motherboard.
  • 5 beeps - Processor failure. The system CPU has failed.
  • 6 beeps - Gate A20/keyboard controller failure. The keyboard IC controller has failed, preventing gate A20 from switching the processor to protect mode.
  • 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 interact with the CMOS.
  • 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.
Phoenix Beep Codes

Phoenix uses sequences of beeps to indicate problems. The "-" between each number below indicates a pause between each beep sequence. For example, 1-2-3 indicates one beep, followed by a pause and two beeps, followed by a pause and three beeps. Phoenix version before 4.x use 3-beep codes, while Phoenix versions starting with 4.x use 4-beep codes.

Could it be the problem with motherboard when a PC having worked for sometme then shut down and could not boot again, only the serial number of the PC is displayed on the screen?

No....BIOS beep codes are just that> They have specific information to tell them when something is not right and the accepted way of transferring that information is by using the beep codes.

Your problem seems to come from a hard drive failure.
