Beep code
The computer can emit a series of beeps during start-up if the display does not show errors or problems. These series of beeps, called
beep codes, identify various problems. The delay between each beep is 300 ms, the delay between each set of beeps is 3 sec, and the
beep sound lasts 300 ms. After each beep and each set of beeps, the BIOS should detect if the user presses the power button. If so, BIOS
will jump out from looping and execute the normal shutdown process and power system.
