chip on the motherboard (CMOS). It controls systems devices and test memory. It allows you to configure specific parameters about the hardware http://www.bndsys.com/SupportDocs/ErrorMessages/BiosBeepCodes.htm in your computer such as time, date, disk drive parameters and other device https://en.wikipedia.org/wiki/Power-on_self-test settings. Beeps are emitted from a computer during the boot process when some problem is encountered and can be used to troubleshoot a dead computer. They indicate problems such as bad memory, bad keyboard or bad motherboard. Usually if you hear beeps there is something real wrong and you should immediately turn off beep codes the computer and perform some troubleshooting. POST Beeping Error General Codes Bad Motherboard - 1 long and 1 short beep Disk drive related problem / Video card problem - 1 short beep then nothing happens Bad video card - 1 long and 2 short beeps Bad power supply - 1) continuous beeps, 2) non-stop short beeps Bad memory - 3 short beeps These codes DO vary list bios error from one manufacturer to another. Almost all computers list the appropriate codes in the User's manual under technical information or the troubleshooting section, so be sure to check the manual and verify what the codes mean. If no beeps are heard and no display is on the screen, it's most likely the power supply. Check for Keyboard lights or for hard drive/floppy drive lights. If lights come on then power supply is good. Next, inspect the motherboard for loose components. A loose or missing CPU, BIOS chip, Crystal Oscillator, or Chipset chip will cause the motherboard not to function. If there are lights, then it could be one of the I/O cards. Try removing each card one at a time and restarting the computer.

Sometimes, it is shown 'Boot from CD'. (AMI BIOS) A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. This article mainly deals with personal computers, but many other embedded systems such as those in major appliances, avionics, communications, or medical equipment also have self-test routines which are automatically invoked at power-on. The results of tests run by the POST may be displayed on a panel that is part of the device, output to an external device, or stored for future retrieval by a diagnostic tool. Since a self-test might detect that the system's usual human-readable display is non-functional, an indicator lamp or a speaker may be provided to show error codes as a sequence of flashes or beeps. In addition to running tests, the POST process may also set the initial state of the device from firmware. In the case of a computer, the POST routines are part of a device's pre-boot sequence and only once they complete successfully is the bootstrap loader code invoked to load an operating system.

These other duty-specific programs are generally known collectively as option ROMs or individually as the video BIOS, SCSI BIOS, etc. The principal duties of the main BIOS during POST are as follows: verify CPU registers verify the integrity of the BIOS code itself verify some basic components like DMA, timer, interrupt controller find, size, and verify system main memory initialize BIOS pass
