Chip_BIOS

When A system  is first powered on , the system Runs A POST . if error are encountered during the POST ,you usually see a TEXT error message displayed onscreen .Error that occur very early in the POST may occur before the video card is initialized.These type of errors can not be displayed ,so the system uses a series of beeps for communicating the error messages .The  system pauses if any of the hardware connected to the system is not Functioning properly .
