BIOS ring code
When the computer can't start, the machine's charging self-test program POST will issue some prompt information from the PC speaker, so that you find a failed component. Thus, the meaning of the sound issued by the computer is very helpful to solve various problems. Below, in the following, in accordance with different companies' BIOS, the meaning of ring codes.
Award BIOS
1 short system starts normally
2 short regular errors, please enter the CMOS setup to reset the incorrect option
1 length 1 short memory or motherboard error
1 length 2 short display error (display or display card)
1 length 3 short keyboard controller error
1 length 9 short motherboard FlashRam or EPROM error (BIOS damage)
Constantly ringing (long-ever) memory plugging or damage
Keep the power supply, the display is not connected to the display card
Repeat short power problems
No sound without display power problems
Ami BIOS
1 short memory refresh failed
2 short memory ECC calibration error
3 short system basic memory (1st 64K) check failed
4 short system clock error
5 Short Central Processor (CPU) error
6 short keyboard controller error
7 Short system real mode error, can not switch to protection mode
8 short display memory errors (display memory may be broken)
9 short ROM BIOS inspection and error
1 length 3 short memory error (memory damage, please replace)
1 length 8 short display test error (display data line is loose or displayed)
Phoenix BIOS
1 short system starts normally
3 short system power-on self-test initialization (POST) failed
1 short 1 short 2 short motherboard error (the motherboard is damaged, please replace it)
1 short 1 short 3 short motherboard battery is dead or CMOS damage
1 short 1 short 4 short ROM BIOS verification error
1 short 2 short 1 short system real-time clock has problems
1 short 2 short 2 short DMA channel initialization failed
1 short 2 short 3 short DMA channel page register error
1 short 3 short 1 short memory channel refresh error (problem range is all memory)
1 short 3 short 2 short volume error (memory damage or RAS setting error)
1 short 3 short 3 short volume memory errors (most likely to be damaged on the DIMM0 slot)
1 short 4 short 1 short volume memory error
1 short 4 short 2 short system basic memory (1st 64K) has parity error
1 short 4 short 3 short EISA bus timeout errors
1 short 4 short 4 short EISA NMI mouth error
2 short 1 short system basic memory (1st 64K) check failed 3 short 1 short 1 short first DMA controller or register error
3 short 1 short 2 short second DMA controller or register error
3 short 1 short 3 short interrupt processing register error
3 short 1 short 4 short sub-break processing register error
3 Short 2 short 4 short keyboard clock has problems, reset it in CMOS to not installed to skip POST
3 short 3 short 4 short display card RAM error or no RAM, do not belong to fatal errors
3 Short 4 short 2 short display data line loose or display card insertion or display card damage
3 short 4 short 3 short unfassed ROM BIOS
4 short 2 short 1 short system real-time clock error
4 short 2 short 2 short system startup error, CMOS is not properly or BIOS damage
4 Short 2 short 3 short keyboard controller (8042) is wrong, BIOS cannot switch to protection mode.
4 short 2 short 4 short protection mode interrupt error
4 short 3 short 1 short memory error (memory corruption or RAS setting error)
4 short 3 short 3 short system second clock error
4 short 3 short 4 short real-time clock error
4 short 4 short 1 short serial port (COM port, mouse mouth) fault
4 short 4 short 2 short parallel port (LPT port, print port) error
Lingll said: For the Award BIOS, 1 long 3 is "keyboard controller error", but finally found that the graphics card is not plugged, doubtful
