Error and Informational Messages
When you turn on the system, POST displays messages that provide information about the system.
If a failure occurs, POST emits beep codes that indicate errors in hardware, software, or firmware.
If POST can display a message on the video display screen, it causes the speaker to beep twice as
the message appears.
Port-80 Codes and Countdown Codes
After the video adapter has been successfully initialized, the BIOS indicates the current testing
phase during POST after the video adapter has been successfully initialized by outputting a 2-digit
hex code to I/O location 80h. If a port-80h ISA POST card is installed, it displays the 2-digit code
on a pair of hex display LEDs. Refer to the POST card documentation for a listing of specific
errors.
