Let's learn the meaning of the BIOS alarm

Computer Store News It is estimated that every new user who is exposed to the computer is quite impressed by the length of the beep that sounds when the computer is not booting properly. Because the computer can't start normally, and it keeps calling, the novices don't know how to deal with it. This is really distracting and helpless. In fact, this represents a malfunction of the computer and requires us to eliminate it. The regular buzzer is the pre-set prompt sound of the motherboard BIOS. We can judge the problem according to different types of BIOS. Below, let us learn the meaning of the BIOS alarm. First, what is the BIOS? First of all, let's first understand what is the BIOS? The BIOS (basic input output system) setting program is a set of programs that are solidified into the ROM chip on the computer motherboard. Its main function is to provide the lowest level and most direct hardware setting and control for the computer. The BIOS setup program is stored in the BIOS chip and can only be set at boot time. CMOS is mainly used to store the parameters and data set by the BIOS setup program, while the BIOS setup program mainly manages and sets the basic input/output system. Second, the type of BIOS There are three major types of BIOS: AWARD, AMI and PHOENIX, but AWARD has acquired PHOENIX, perhaps because of this relationship, PHOENIX-AWARD BIOS will appear. And because AWARD's BIOS interface is more friendly, the current motherboard BIOS is mostly AWARD. On the current motherboard, we can see the following two kinds of BIOS which are more common, which is produced by Winbond.

Third, different types of BIOS alarm sound meaning I have already said some knowledge about the BIOS, I believe that everyone has a preliminary understanding of the BIOS. The following is a good news, to introduce the specific meaning of the computer boot self-test alarm sound. Award BIOS: 1 short: The system starts normally. 2 short: regular error. Please go to CMOS SETUP to reset the incorrect option. 1 long 1 short: memory or motherboard error. 1 long 2 short: display error (display or display card). 1 long 3 short: keyboard controller error. 1 long 9 short: motherboard flashRAM or EPROM error (BIOS corrupted). Constantly ringing (long sound): The memory is not stable or damaged. Reinsert the memory module. If it still does not work, only replace one memory. Keep ringing: The power supply and monitor are not connected to the display card. Repeat short sound: power problem. No sound, no display: power problem. AMI BIOS: 1 short: memory refresh failed. Memory damage is more serious, I am afraid you have to replace the memory. 2 short: Memory ECC (parity) check error. You can enter the CMOS settings and turn off the memory Parity parity option, which is set to Disabled. However, in general, the memory stick has parity and the parity is turned on in the CMOS settings, which is good for the stability of the computer system. 3 short: System basic memory (1st 64K) check failed. Replace the memory. 4 short: The system clock is wrong. Repair or replace the motherboard. 5 short: CPU (CPU) error. But not necessarily all the fault of the CPU itself, it may be a problem with the CPU socket or some other place. If the CPU is normal on other motherboards, the error must be in the motherboard. 6 short: keyboard controller error. If the keyboard is not plugged in, it is easy to do, just plug it in. If the keyboard is connected properly but there is an error, try changing to a good keyboard. Otherwise, there is a problem with the keyboard control chip or related parts. 7 short: The system real mode is wrong and cannot be switched to protected mode. The fault of the motherboard. 8 short: Display memory error (display memory may be broken). The memory chip on the graphics card may be damaged. If the memory slice is pluggable, just find the bad one and replace it, otherwise the graphics card needs to be repaired or replaced. 9 short: ROM BIOS checksum error. Try changing the block with the same type of good BIOS. If you prove that the BIOS has a problem, you can try to recover by rewriting or even hot plugging. 10 short: CMOS shutdown register read/write (register read/write) error. Repair or replace the motherboard. 11 short: Cache memory error. 1 long 3 short: memory error. Memory damage needs to be replaced) 1 long 8 short: display test error. The display data cable is loose or the display card is not stable. Phoenix BIOS: 1 short: The system starts normally. 3 short: System power-on self-test initialization (POST) failed. 1 short 1 short 2 short: motherboard error (main board is damaged, please replace). 1 short 1 short 3 short: The motherboard battery is dead or CMOS damaged. 1 short 1 short 4 short: ROM BIOS check error. 1 short 2 short 1 short: There is a problem with the system real time clock. 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: basic memory error (memory corruption or RAS setting error). 1 short 3 short 3 short: basic memory error (probably memory damage on DIMM0 slot). 1 short 4 short 1 short: An error occurred in the basic memory address. 1 short 4 short 2 short: system basic memory (1st 64K) has parity: error. 1 short 4 short 3 short: EISA bus sequencer error. 1 short 4 short 4 short: EISA NMI port error. 2 short 1 short 1 short: system basic memory (1st 64K) check failed.
