Debug card

The debug card is a diagnostic tool for technicians to configure the system BIOS settings and conveniently troubleshoot various problems. This card can help you track the progress of a Power-On Self Test (POST) and discover the cause of errors during system operations. The debug card connects to the system via its debug card cable connector. It includes a VGA port for connecting an external monitor to view BIOS output checkpoints. The debug card also provides a PS/2 mouse port, PS/2 keyboard port and a serial port.
