Beeps BIOS Beeps BIOS can "tell" the experienced user fault of his personal computer.But these signals need to be able to properly decipher.Land of the Soviets will talk about values ​​beeps major versions BIOS.

BIOS, among other things responsible for the initial testing of computer components (POST).Test results reported by the BIOS beep , reproduced thanks to the integrated speaker.BIOS beep codes vary in duration.By the combination of these signals to determine fault.

Beeps BIOS vary among brands BIOS.The most common version of the BIOS - it AMI BIOS, AWARD BIOS and Phoenix BIOS .To determine what your BIOS, you should enter the BIOS Setup: the brand name will be written at the top of the screen.In addition, the mark is written on the chip BIOS, which is located on the motherboard.
