Table 87 describes the lower nibble of the high byte and indicates the bus on which the routines are
being executed.
Table 87.
A 47 Ω inductive speaker is mounted on the Desktop Board D845EBG2 and the Desktop Board
D845EPT2. The speaker provides audible error code (beep code) information during POST.
Whenever a recoverable error occurs during POST, the BIOS displays an error message describing
the problem (see Table 88). The BIOS also issues a beep code (one long tone followed by two
short tones) during POST if the video configuration fails (a faulty video card or no card installed)
or if an external ROM module does not properly checksum to zero.
An external ROM module (for example, a video BIOS) can also issue audible errors, usually
consisting of one long tone followed by a series of short tones. For more information on the beep
codes issued, check the documentation for that external device.
There are several POST routines that issue a POST terminal error and shut down the system if they
fail. Before shutting down the system, the terminal-error handler issues a beep code signifying the
test point error, writes the error to I/O port 80h, attempts to initialize the video and writes the error
in the upper left corner of the screen (using both monochrome and color adapters).
