2.14 Keyboard/ Mouse Connector (CN4)

The PCM-5335 board provides a pin head er 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. If
the keyboard is not present, the standard PC/AT BIOS will report an
error or failure during the power-on self test (POST) after resetting
the PC.
The PCM-5335 board's BIOS standard setup menu allows you to
select "Absent/Present" for your keyboard under the Advanced
CMOS Setup section. This allows non-keyboard operation in
embedded system applications without the system halting during the
POST.
When "PS/2 mouse support" is enabled, your PS/2 mouse is
automatically detected by the system
