BiOS self-check Bell and Its Significance

General BIOS self-check Bell and Its Significance

1 short: failed to refresh the memory. Replace the memory stick.
2 short: Memory ECC is incorrect. In CMOS setup, setting the ECC check option to disabled can solve the problem. However, the most fundamental solution is to change the memory.
3 short: the system basic memory (1st 64kb) Check failed. Change memory.
4 short: system clock error.
5 short: the CPU is incorrect.
6. Short: the keyboard controller is incorrect.
7. Short: The system real-time mode is incorrect and cannot be switched to the protection mode.
8: memory error is displayed. The Display memory is faulty. Try changing the video card.
9 short: rom bios check and error.
1 long 3 short: memory error. Memory Corruption. Change the memory.
1 long, 8 short: The test error is displayed. The display data line is not plugged in or the display card is not plugged in

Award bios self-check Bell and Its Significance

1 short: the system starts normally. This is what we can hear every day, and it also indicates that the machine has no problems.
2 short: A general error occurs. Enter CMOS setup and reset the incorrect options.
1 long and 1 short: an error occurs in Ram or the motherboard. Try another memory. If it still doesn't work, you have to replace the motherboard.
1 long 2 short: Incorrect display or display card.
1 long, 3 short: Incorrect keyboard controller. Check the motherboard.
1 length 9 short: The Flash Ram or EPROM on the motherboard is incorrect and the BIOS is damaged. Try changing block Flash Ram.
constant sound (long sound): the memory stick is not plugged in or damaged. Re-insert the memory stick. If the memory stick still does not work, replace
a memory stick.
the power supply and display are not connected to the display card. Check all the plugs.
duplicate short response: power supply problem.
no sound, no display: power supply problems.
