How to determine the alarm sound of the computer boot?

Award BIOS:

1 short: The system starts normally

2 short: General error. WORKAROUND: Reset the BIOS

1 long 1 short: RAM or motherboard error

1 long 2 short: monitor or display card error

1 Long 3 short: Keyboard controller error

1 Long 9 short: motherboard flash RAM or EPROM error, BIOS damage

Keep ringing (long sound): the memory strips are not plugged in or damaged

Do not listen to the sound: power supply, monitor does not connect with the video card good

Repeat short ring: power supply problem

No sound no display: There is a problem with the power supply

AWI BIOS:

1 Short: Memory refresh failed. Workaround, replace the memory bar

2 short: Memory ECC parity error. Workaround: Go to CMOS settings and turn ECC off

3 Short: System basic memory (first 64KB) check failed

4 Short: System clock error

5 Short: CPU Error

6 Short: Keyboard Controller error

7 short: System Real mode error, can not switch to protection mode

8 Short: Memory error

9 Short: ROM BIOS check and error

1 Long 3 short: Memory error

1 Long 8 short: Display test error

Phoenix BIOS

1 Short: System boot normal

1 short 1 Short 1 short: System dot self-test initialization failed

1 short 1 Short 2 short: motherboard error

1 short 1 Short 3 short: CMOS or battery error

1 short 1 Short 4 short: ROM BIOS parity failure

1 short 2 short 1 short: System clock error

1 Short 2 short 2 short: DMA initialization failed

1 Short 2 short 3 short: DMA page Register error

1 Short 3 short 1 short: Ram Refresh error

1 Short 3 short 2 short: basic Memory error

1 short 4 Short 1 short: basic memory Address line error

1 Short 4 Short 2 short: basic Memory parity Error

1 Short 4 short 3 short: EISA Sequencer error

1 Short 4 Short 4 short: EASA nmi mouth error

2 short 1 short 2 short to 2 short 4 short 4 short (ie all starting with 2 short sound combinations): Basic memory error

3 short 1 short 1 short: Error from DMA register

3 Short 1 Short 2 short: Primary DMA Register error

3 Short 1 Short 3 short: main Interrupt processing Register error

3 Short 1 Short 4 short: error handling registers from interrupt

3 Short 2 short 4 short: Keyboard Controller error

3 Short 3 Short 4 short: Display Card memory error

3 Short 4 Short 2 short: Display error

3 Short 4 Short 3 short: No display read-only memory

4 Short 2 short 1 short: clock error

4 Short 2 short 2 short: shutdown error

4 Short 2 short 3 short: A20 Gate Error

4 Short 2 Short 4 short: protection mode interrupt Error

4 Short 3 short 1 short: Memory error

4 Short 3 short 3 short: Clock 2 error

4 Short 3 Short 4 short: Real clock error

4 Short 4 Short 1 short: Serial port error

4 Short 4 Short 2 short: Parallel port error

4 Short 4 Short 3 short: Digital coprocessor error

Compatible BIOS:

1 Short: System normal

2 short: System Power On Self Test (post) failed

1 Long: Power supply error, if no display, then card error

1 long 1 short: motherboard error

1 long 2 short: Video card error

1 short 1 short 1 short: power supply error

3 Long 1 short: keyboard error
