Selecting the Base Memory Address Location
The host computer and the card exchange data via a dual-port interface. The
dual-port interface is 16 Kbytes long; it begins at the specified base memory
address location.
The card comes set to memory address D000:0000. You may find that this
selected memory address has been allocated to other interface cards or expansion
memory cards you have installed in your computer system. If this occurs,
change the switch settings to an available memory address.
To select a new base memory address:
1. Pick an available address from the ROM I/O adapters area of the host
computer’s memory.
Be sure to choose a block that is 16 Kbytes long.
2. Us Worksheet A to select a new memory address for the card.
3. Use Worksheet B to determine the proper switch settings.
Follow this guide to properly set your switches.
