PCI Bus Card for 1746 Local I/O 5
Publication 1747-5.31–April 1998
Setting the Base Memory Address Jumper
The host computer and the PCI Bus card exchange data via a dual-port
interface. The dual-port requires 4 Kbytes of memory. This 4 Kbyte block
of memory begins at the base memory address assigned to the card by the
PCI BIOS when the computer is started.
Under MS-DOS, Windows 3.1 and Windows for Workgroups, the base
memory address of PC cards should fall within the range of 0 and 1
Megabyte of PC memory. For the newer 32-bit operating systems, this
restriction is no longer required, and the base memory address should be
located anywhere in the PC memory space.
The Base Memory Address jumper (JP2) forces the PCI BIOS to assign
the base memory address to one of two address ranges, as shown in the
table below. You should select the jumper position based on the operating
system running on your PC.
When looking directly at the 1747-PCIS card, the Base Memory Address
jumper looks like this:
Operating System Jumper Position (JP2) Base Memory Address Range
DOS
Windows 3.1
Windows for Workgroups
Non-Microsoft system Toward 1Meg position Located in the range between 0 and
1Mb in the PC memory
Windows 95
Windows NT Toward 32bit position Located anywhere in the available
physical memory of the PC
This is a jumper that has the 32bit
position for Windows 95 covered.
This is a jumper that is not covered.
