GPIB Plug and Play Board Undetected by Windows 98/95/Me

Hardware: GPIB>>Plug-in Controllers>>AT-GPIB/TNT (PnP)

Problem:
My GPIB plug and play board is not being detected by my Windows 98/95/Me system. What can I do to fix this?

Solution:
If you have plugged in your board before installing the NI-488.2 driver, then your board will not be listed under "National Instruments GPIB Interfaces" in the Device Manager. Since the NI-488.2 driver acts as the interface between your GPIB board and the operating system (and any GPIB programs), Windows 98/95 will place your board in the "Other Devices" category in the Device Manager.

This may also be the problem if you did not see a "New Hardware Found" message when you installed your board, or you are getting an EDVR error when you try to access your GPIB interface.


To fix the problem, complete the following steps:

  1. Under Start » Settings » Control Panel » System, select the Device Manager tab.

  2. In the Device Manager window, look for an entry called "Other Devices" and double-click on it. You should see something like the following (the board shown here may not be the same as yours):

    Other Devices


      If you don't find anything under "Other Devices", then see the information under "Other Troubleshooting Tips" (below).


  3. Left-click once on your board to highlight it and then click on the Remove button to remove the board from the Other Devices category.

  4. Click on the Refresh button. This should force Windows 98/95 to rebuild its driver database and then re-examine the plug and play boards present in your system. Windows 98/95 should find your board again and list it under National Instruments GPIB Interfaces.


Other Troubleshooting Tips

  • If your board continues to be listed under "Other Devices", even though you have removed the board from this device category and refreshed the driver list:

    1. Go to your windows\inf directory (this is normally a hidden directory, but you can change your View menu option to display hidden files) and delete the "drvdata.bin" and the "drvidx.bin" files from this folder. Deleting these files will force Windows 98/95 to rebuild its driver database.

    2. Reboot your system. (You do not need to remove your board.) When your system reloads Windows 98/95, you should see a "New Hardware Found" message and a message that the driver database is being rebuilt.

    3. Go to your Device Manager. Your board should now be listed under "National Instruments GPIB Interfaces".


  • If your board is not listed under "National Instruments GPIB Interfaces" or "Other Devices":

    1. Close all applications and power off your computer.

    2. Physically remove the board from the computer and reboot your computer without the board.

    3. Open the Device Manager and make sure your board is not listed there. If it is, then remove it again, using the Remove button.

    4. Power off your computer again and reinsert the board (preferably in a different slot).

    5. When you power up your system again, your board should now be listed under "National Instruments GPIB Interfaces" in the Device Manager.


  • Are you sure you have plug and play hardware?

  • Otherwise, if your board is still not detected:

      PCI Boards: Use our Request Support page to contact National Instruments for assistance. Please mention that you have already followed the troubleshooting advice given here.


      ISA Boards: You may need to edit your Windows Registry to remove any incorrect information about the board that may be in there.


      PCMCIA Cards: Make sure that the 32-bit PCMCIA drivers are enabled. Under Start » Settings » Control Panel » System, select the Performance tab and look at the "PC Cards (PCMCIA):" line. If it reads "32-bit", then the 32-bit PCMCIA drivers are enabled.

        Enabled: If the 32-bit PCMCIA drivers are enabled, then repeat steps 1-4 again.

        Disabled: If the 32-bit PCMCIA drivers are not enabled, enable them by running the PC Card (PCMCIA) Wizard, a Control Panel applet found under Start » Settings » Control Panel » PC (PCMCIA). After enabling 32-bit PCMCIA drivers, you need to shut down your computer and restart it. When your computer restarts, your PCMCIA-GPIB should be detected, assuming it has been inserted, and a "New Hardware Found" message should appear. If no "New Hardware Found" message appears and your GPIB card is not listed in the Device Manager, then use our Request Support page to contact National Instruments for assistance. Please mention all of the troubleshooting steps you have taken.


      GPIB-USB: Use our Request Support page to contact National Instruments for assistance. Please mention that you have already followed the troubleshooting advice given here.


  • If you are getting an EDVR error, and your board is listed correctly under "National Instruments GPIB Interfaces" in the Device Manager:

      Your board's interface name may be set to "None". You can check this by pressing the Properties button in the Device Manager, and selecting the NI-488.2 Settings tab in the board properties window. If the Interface Name is set to "None", then select "GPIB0" instead. This is the default interface name for the first GPIB board that you install in your computer. Additional boards would have similar interface names: "GPIB1", "GPIB2", etc.
