POST Codes

9. POST Codes
In order to indicate progress through BIOS POST, and in special cases where errors are
encountered during BIOS POST, three common mechanisms are employed by the SR870BH2
BIOS.
The first and most common method is Audible, encoded beep sequences emitted by the
PC speaker when an error is encountered. Beep codes are employed before the display
screen is enabled, and generally indicate fatal errors. Beep codes are coupled with
special port 80 error codes.
The second method is to display an error message to the display screen after the Video
has been initialized.
The third method is to display port 80/81 codes to an I
board. This method is described as an option but is beyond the scope of this document.
