PCINT:

This program is used when PCI-bus cards are used in WindowsNT operating

systems.  It runs only on WindowsNT. There are three files as follows:

PCINT.TXT:

Contains instructions on use of these files.

PCINT.EXE:

This is an installation program and utility for NTioPCI.SYS.  You run this

program to both install and to use NTioPCI.SYS. The program displays

resources allocated by the system for an installed PCI-bus card.  Under

WindowsNT, this program is used rather than PCIFind.exe. (The latter is

used when PCI-bus cards are run under DOS, Windows 3.1 or Windows95.)

NtioPCI.SYS:

This file is installed by PCINT.EXE and is used to determine the configuration

of an installed PCI-bus card.

Installing The Card

The PCI-WDT50x card can be installed in a five-volt PCI slot of an IBM or compatible computer.

Before installing the card, carefully read the 

Option Selection

 section of this manual and config-

ure the card according to your requirements.  Finally, our SETUP.EXE program will lead you

through the process of setting the options on the PCI-WDT50x.  The setup program does not set the

options.  These must be set manually by jumpers on the card.

To install the card:

1. Turn OFF computer power.
2. Remove the computer cover.
3. Install jumpers from either the 

Option Selection

 section of this manual or the suggestions of

our SETUP.EXE software program.

4. Install the card in an available PCI-bus slot.  You may need to remove a backplate first.
5. Inspect for proper fit of the card and tighten screws.

 Make sure that the card mounting bracket

is properly screwed into place and that there is a positive chassis ground.

6. Replace the computer cover and turn the computer ON.
7. Enter the CMOS setup program of your system and verify that the PCI plug-and-play option is

set appropriately for your system.  Systems running Windows95 (or any other PNP-compliant

operating system) should set the CMOS option to OS.  Systems running under DOS, WindowsNT

3.51, Windows 3.1, or any other non-PNP-compliant operating system should set the PNP

CMOS option to BIOS or Motherboard.  Save the option and continue booting the system.

If you are using Windows95, your operating system should detect the new hardware and prompt

you for the installation disk.  The simplest option is to insert the provided diskette into the A drive

and allow the operating system to look for the files that it wants.

Alternatively, if you have already installed the software to your computer, you can specify the

installation directory instead of allowing Windows95 to look around.  Either option will work

acceptably.  Please note that even though Windows95 looks for and finds software to install, no

driver is actually installed, used, or needed.  This step merely tells Windows95 where to place the

card in the registry of devices.  You can find the installed card in Device Manager, under the class

Data Acquisition.  Use this method to determine the card’s base address as PCIFind.EXE may or

may not work under your specific installation of Windows95.
