Intel PCM-9387 user manual Keyboard and PS/2 mouse connector CN14, Power & HDD LED Connector CN10

2.9 Keyboard and PS/2 mouse connector (CN14)

The board provides a keyboard connector that supports both a keyboard and a PS/2 style mouse. In most cases, especially in embedded applica- tions, a keyboard is not used. If the keyboard is not present, the standard PC/AT BIOS will report an error or fail during power-on self-test (POST) after a reset. The PCM-9387’s BIOS standard setup menu allows you to select “All, But Keyboard” under the “Halt On” selection. This allows no-keyboard operation in embedded system applications, without the sys- tem halting under POST.
