7.2 Debug Tool

Cavaliere 141 MB would not support Parallel Port, then we could not plug the Debug Card to PIO
Port to get the Port 378
that are parallel connection with PIO output lines(Figure 1),when the system BIOS write the error
code to Port 378, the LEDs can show the messages.
Maybe the LEDs have not been mount on the mother board, you must place the LEDs for
getting error code.(Figure 2)
