Switch 1 = 200h (512D) and switch 2 = 100h (256D). Added together, they equal
300h (768D), the base address.

Figure 3-1. Address Switches and Pin 1 Locations

Certain addresses are used by the PC while others are free and can be used by the
PC104-DO48 and other expansion boards. We recommend trying the factory default
address, 300h (768D), first.
