Configuring the 9220-KTCT
Before installing the 9220-KTCT inside your computer, you must
determine if you need to change the card’s default physical addresses.
This address
À
Specifies
base memory address 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.
base I/O space address the host processor’s I/O map—so the card’s I/O devices can
receive commands from the host computer.
À
You can have as many as four 9220-KTCT cards in one computer as long as each has different base
memory and base I/O space addresses.
To reset these addresses, you set switches on the card. The 9220-KTCT
comes factory-set with these 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 unique addresses
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 there is a conflict, the system will not
operate properly.
•
you cannot mix 8-bit and 16-bit cards in a 64K segment boundary
That is, a 9220-KTCT and 1784-KT/B cannot be placed in the same
segment range of D000:0000 – DFFF:0000 or C000:0000 –
CFFF:0000. The 8-bit card may not work in this setup.
The two cards, 9220-KTCT (16-bit) and KT/B (8-bit), can be placed
with one in the C000:0000 – CFFF:0000 range and one in the
D000:0000 – DFFF:0000 range.
