AST BIOS
  • One short --> CPU register test failure
  • Two short --> Keyboard controller buffer failure
  • Three short --> Keyboard controller reset failure
  • Four short --> Keyboard communication failure
  • Five short --> Keyboard input failure
  • Six short --> System board chipset failure
  • Nine short --> BIOS ROM checksum error
  • Ten short --> System timer test failure
  • Eleven short --> ASIC failure
  • Twelve short --> CMOS RAM shutdown register failure
  • One long --> DMA controller 0 failure
  • One long, one short --> DMA controller 1 failure
  • One long, two short --> Video vertical retrace failure
  • One long, three short --> Video memory test failure
  • One long, four short --> Video adapter failure
  • One long, five short --> 64KB memory failure
  • One long, six short --> Unable to load interrupt vectors
  • One long, seven short --> Unable to initialize video
  • One long, eight short --> Video memory failure
IBM BIOS
  • Two short --> Initialization error
  • One long, one short --> System board error
  • One long, two short --> Video adapter error
  • One long, three short --> EGA/VGA adapter error
  • Three long --> keyboard adapter error
  • Continuous --> Power supply error
  • No beep --> Power supply
Award Bios
  • One long, two short --> Video adapter error
  • Repeating (endless loop) --> Memory error
  • One long, three short --> No video card or bad video RAM
  • High frequency beeeps while running --> Overheated CPU
  • Repeating High/Low --> Either the CPU is not seated properly or the CPU is damaged
