The net6501 does not support video or keyboard at all.

Console Serial port on db9 connector is COM1 on LPC interface.
Internal Serial port on 10 pin header is UART0 on the EG20T.
Both with full handshake.

Two USB ports goes to the mini PCIe slots.
Two USB ports goes the the standard 10 pin USB header JP4.
