Keyboard and mouse connector (CN9)
The mainboard provides a keyboard connector which supports
both a keyboard and a PS/2 style mouse. In most cases, especially
in embedded applications, a keyboard is not used. The standard
PC/AT BIOS will report an error or fail during power-on self-test
(POST) after a reset if the keyboard is not present. The mainboard
BIOS Advanced setup menu allows you to select "System Key-
board" under the "Present" or "Absent" selection. This allows no-
keyboard operation in embedded system applications without the
system halting under POST (power-on-self-test).
