Switch 1 corresponds to the least significant bit of a block of 32 byte I/O port addresses. When it is in the off position, it sets bit 5 of the address, and its numerical weight is 20 hexadecimal. Switch 5 corresponds to the most significant bit of a block of 32 byte I/O port addresses. When it is in the off position, it sets bit 9 of the address, and its numerical weight is 200 hexadecimal.

I/O addresses below 100 hexadecimal are reserved for the system board

NOTE: of the host computer. Setting the LiveGateway board I/O address below 100 hexadecimal may interfere with the operation of the host computer.
