Configure the Card Hardware
Before you install the KTx card inside your computer, you must set the:
• base memory address - the card’s physical addresses for the expansion
memory area of the host processsor’s system memory, that enables the KTx
card and the host computer to exchange data through the dual-port interface
• card’s interrupt setting
Select the Base Memory Address Location
The host computer and the KTx card exchange data via a dual-port interface. The
dual-port interface requires 4 Kbytes of memory (2 Kbytes for dual-port and 2
Kbytes for the rest of the interface). It begins at the specified base memory
address location. You must select an area where there is at least a 4 Kbyte
memory block available. If you have MS-DOS 6.0 or later, use the memory
option in Microsoft Diagnostics (MSD) to identify available memory.
The 1784-KTx cards come set to memory address(es):
