Beep Codes

The computer may emit a series of beeps during start-up if the display cannot 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 seconds, 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.
