Power ON Self Tests are what the BIOS conduct automatically to check the buss traffic and see if there are any tie ups. Also known as BEEP Codes, they cause the computer to beep the first time it is started up. If the computer has a working speaker you can use this function of the BIOS. It requires that you know who made the BIOS and what their BEEP Codes are.
