Keyboard and PS/2 mouse connector
(CN14)
The PCM-4897 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 main-
board BIOS Advanced setup menu allows you to select "Present"
or "Absent" under the "System Keyboard" section. This allows
no-keyboard operation in embedded system applications without
the system halting under POST (power-on-self-test).
