(See the POST code references in the system manual that shipped with the PC or the motherboard to obtain references for detailed error messages and beeps.) The following table lists the basic beep codes for AMI and Phoenix BIOSs. Some error codes are specific to chip sets or custom products, and the exact message and its meaning can vary from system to system. This is also done by beep codes and (if possible) screen prompts. If a problem occurs, the POST routine attempts to report the problem. The POST is a good indication that the hardware is in working order. Then it transfers control to the boot drive, and the operating system is loaded. In a healthy system, the POST reports by using a series of beep codes and screen messages to convey that all components are working. The exact order, number of tests, and error states will vary from product to product. The purpose of the first POST test is to check the most basic components. Beep Codes Before and During the Video Test If something goes wrong, the POST sends a series of beep codes to let you know what the problem is or where to start looking for it. Depending on the BIOS type, the POST might also sound a single beep when it's done, to let you know the boot process was successful. The POST does assume that the speaker always works, but in order to let you know that the speaker is working, all computers beep on startup. The POST does not assume the video works until it has been tested. This division determines whether the computer will display errors by beeping or showing them on the screen. Test 2 occurs after the video has been tested.Test 1 occurs before and during the test of the video.
