more information on LCD codes.
4.6 System Management Service (SMS)
The SMS programs make it possible for you to view information about your
computer, run memory tests and set the device from which the server will boot.
By default, the firmware uses the serial port S1 to display logos, messages, errors,
and also as the interface to the SMS programs. If a supported graphics adapter is
installed in the machine, the firmware will redirect the output to this adapter instead
of the serial port. It means, if you have installed a graphics adapter but you want
to use an ASCII terminal attached to serial port S1 as the console for the SMS
programs, then you will have to remove the graphics adapter first.
The SMS programs provide two types of interfaces: a graphical user interface
which can be used on a graphical display and an ASCII interface which can be
used either on an ASCII terminal or on a graphical display.
Note: The ASCII interface provides more functions than the graphical interface.
