2.1.3 LCD Display Module
The LCD display is an 8-line by 16-character screen that indicates the
boot status as well as any BIOS checkpoint errors encountered upon
system initialization. Normally, the system BIOS and the micro-
controller firmware send the LCD display messages that appear on
the screen. However, if you hooked up a special purpose driver to
control the LCD module, this driver defines the messages. See the
driver manual for more information. For a lists of LCD messages
from the system BIOS, please refer to Appendix A.
