Configuring the Card Hardware
Before you install the card inside your computer, you must set the card’s
physical addresses for the:
•
ROM I/O expansion area of the host processor’s system memory—so the
card and the host computer can exchange data through the dual-port
interface. This is the base memory address.
•
host processor’s I/O map—so the card’s I/O devices can receive commands
from the host computer. This is the base I/O space address.
You can have as many as four KTCX15 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.
If you are: go to:
changing addresses on the card “Selecting the Base Memory Address
Location” on page 6
using the factory-set addresses “Installing the Card” on page 16
