BIOS alarm    
BIOS alarm  

AWARD BIOS ringing the general meaning is:
1 short: System start. This is what we hear every day, and also shows the machine without any problem.
2 short: General error, please enter the CMOS Setup, reset the incorrect options.
1 long 1 short: RAM or motherboard error. Memory for a try, if it does not work, had to replace the motherboard.
1 long 2 short: Monitor or display card error.
1 long 3 short: Keyboard controller error. Check the motherboard.
1 long 9 short: board Flash RAM or EPROM error, BIOS damage. Flash RAM to try for the block.
Continuous ring (long sound): memory is not seated or damaged. Re-insert the memory, if it does not work, only the replacement of a memory.
Kept sound: power supply, display and graphics card connected. Check all the plugs.
Repeating short beeps: Power problems.
No sound no display: power problems.
AMI BIOS ringing the general meaning is:
1 a short sound, memory refresh failure. Memory is seriously damaged, probably have to replace the memory is not.
(2) 2 short beeps, memory parity errors. Can enter the CMOS settings, the option to turn off the memory Parity parity, that is set to Disabled. But in general, there is parity memory and CMOS settings to open in parity, the stability of this computer system is good.
3 three short beeps, the system base memory (1st 64Kb) check failed. Replace the memory bar.
4 four short blasts, the system clock error. Repair or replace the motherboard.
5 five short beeps, CPU error. But not necessarily all the fault of the CPU itself, it could be where the CPU socket or other problem, if the CPU on the motherboard in the other normal, it is certainly wrong is that the motherboard.
6 six short sound, the keyboard controller error. If the keyboard is not plugged in, it easy to handle, plug in the line; if the keyboard is connected properly but there is an error, you may wish to try for a good keyboard; or is the keyboard control chip or the relevant parts of a problem.
7 seven short blasts, the system real-mode error, can not switch to protected mode. This is also part of the motherboard's fault.
8 eight short sound, memory read / write errors. Stored on the chip card may be damaged. If the film is removable storage, simply find and replace a bad chip on the line, or need of repair or replacement card.
9 nine short blasts, ROM BIOS check error. For the block to try the same type of good BIOS, BIOS if that problem,
You can override even the hot way to try to restore.
10 ten short sound, register read / write errors. Only repair or replace the motherboard.
11-Eleven short sound cache errors.
12. If he heard no beep rings do not see the screen display, should first check the power is connected, often easy to neglect in maintenance, not connected to the motherboard power on the boot test. Second is not too small to see what parts inserted,
Such as CPU, memory and so on. Again, unplug all the cards in question, leaving only the graphics card to try. Finally, on the motherboard to find clear (clear) CMOS jumper set to clear CMOS settings, let the BIOS back to factory state. If the monitor or video card and connection, no problems, CPU and memory, no problem, after these steps, the computer still does not show in the boot or ring tones, it can only be the motherboard problem.

POENIX the BIOS alarm sound (the previous owner, there are many POENIX, and can now be acquired AWARD)
