Configuring the Card Hardware
Before you install the card, you must set the card’s physical addresses for the:
•
ROM I/O expansion area of the host processor’s system
memory—enables the card and the host computer to exchange data through
the dual-port interface. This is the base memory address.
•
host processor’s I/O map—enables the card’s I/O devices to receive
commands from the host computer. This is the base I/O space address.
You can have as many as four KTCS cards in one computer as long as each card
has different base memory and base I/O space addresses.
To configure these addresses, you set switches on the card. The card comes
factory-set with these default addresses:
Address Type
Address Setting (hex)
base memory
D000:0000
base I/O space memory
220
Important:
When deciding which addresses to use, remember that each card
in your computer must have a unique base memory address and a
unique base I/O space memory address. If another card in the host
computer is using one or both of the factory-set addresses, you
must change a card’s switch settings to an available address.
