2.11Keyboard and PS/2 mouse connector (CN17)

The PCM-5820 Series board provides a mini-DIN 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-5820 Series board's BIOS standard setup menu allows you to select "All, But Keyboard" under the "Halt On" selection. This allows non- keyboard operation in embedded system applications without the system halting during the POST.
