A. Changing the IRQ Setting for a PCI Adapter

In a computer with a PCI bus, the system BIOS allocates all resources to all PCI devices whether they are on the motherboard or in card slots. As the computer boots up, the BIOS finds out what type of resources (I/O, Memory, IRQ, etc.) each PCI device needs. The BIOS then allocates the resources as it sees fit. The PCI devices cannot request specific resources or in any other way control the resources allocated by the BIOS. The PCI BIOS controls all resource assignments.

In many PCI systems, the CMOS setup program offers user-configurable PCI device settings. Refer to your computer's documentation or start your computer's CMOS setup program to find out what options (if any) are available. If you have questions about configuring IRQs in your system's PCI BIOS, refer to the computer's documentation, contact your dealer, or contact the system's manufacturer.

Some systems have no user-configurable PCI settings. In these systems, try moving the PCI card to a different slot. This sometimes causes the system to allocate a different IRQ to the card.

For network cards, Intel recommends that you:
  • Don't use IRQ 9.
  • Don't use a shared IRQ (if at all possible).
  • Don't use an IRQ used by an ISA or EISA card.
B. Use Device Manager to Check System Resources

The Windows* 95 Device Manager reports the status and settings for all the recognized devices in your system. Use this information to find out which resources are already in use and which are (or can be made) available for your network adapter.
  1. Start Windows* 95.

  2. Click Start, select Settings, then select Control Panel.

  3. Double-click the System icon.

  4. Select the Device Manager tab.

  5. Select Computer at the top of the list of devices, then click Properties.

  6. Examine the list of IRQs to see which one the BIOS assigned to the EtherExpress adapter. If there is a conflict, see A. Changing the IRQ Setting for a PCI Adapter

    Note: If all the IRQs are already in use, you may have to reconfigure, disable, or remove a device from your computer to make an IRQ available for the network adapter. Some users change their sound card to IRQ 9 then use IRQ 5 for the network adapter. Other users disable the COM2 port and use IRQ3 for the network adapter. Since each system is unique, you will have to decide which devices are most important to you and how you want to configure them.

  7. Click OK in the System Properties dialog box when you have finished viewing system resources.
C. Use Device Manager to Add Driver to Other PCI Ethernet Controller

Occasionally Windows* 95 will fail to recognize the EtherExpress™ PRO/10 PCI adapter. When this happens, the Device Manager displays a device category called Other Devices. In this category, you will see a device called Other PCI Ethernet Controller. Use this unidentified device to load the drivers for the PRO/10 PCI adapter.

If the Device Manager shows the PRO/10 PCI adapter in the Network Adapter category, but doesn't show the Other PCI Ethernet controller, see O. Use REGEDIT to Examine the Windows* 95 Registry for instructions on correcting the problem.

  1. Start Windows* 95.

  2. Click Start, select Settings, then select Control Panel.

  3. Click the System icon.

  4. Click the Device Manager tab.

  5. Find the Network Adapter category (if present) and expand it by clicking the plus (+) sign next to it.

  6. Remove the Intel® EtherExpress™ PRO/10 PCI driver (if present) from the Network Adapter category.

  7. Find the Other Devices category (if present) and expand it.

  8. Double-click the Other PCI Ethernet device to display its properties.

  9. Click the Drivers tab.

  10. Click the Change Drivers button.

  11. Choose Network Adapter .

  12. Click Have Disk.

  13. Insert the EtherExpress™ PRO/10 PCI diskette, enter A:\WIN95, then click OK.

  14. Follow the prompts to complete the installation.
D. Use the 32-bit ODI Driver with Novell Client* 32

Novell's* Client 32 shell doesn't work with versions 1.10 and earlier versions of the 32-bit NDIS driver for the EtherExpress™ Pro/10 PCI adapter. Intel has released a 32-bit ODI driver that does work with the Client 32 shell.

  1. Download the file E10PCL32.EXE from Intel's online services.

  2. Execute the archive to extract the files.

  3. Follow the instructions in the file E10PCL32.TXT.
E. Enter the Correct Path to the Windows* 95 Cabinet Files

If Windows* 95 has trouble finding the NETAPI.DLL or other VXD or DLL files, you will need to enter the path to the Windows Cabinet files. The cabinet files reside in either of two locations depending on how you or your dealer installed Windows* 95.

D:\WIN95 (If your CD ROM drive is not D:, substitute the correct letter)

C:\WINDOWS\OPTIONS\CABS

Try the Windows* 95 CD ROM first. If that does not work, look for the OPTIONS\CABS directory on your hard drive. For more help or information, consult the Windows 95 documentation or contact Microsoft.

F. Use Network Setup to Remove Adapter Driver and Reinstall

If the network adapter does not work properly, you can often correct the problem by simply removing the driver, restarting Windows* 95, and reinstalling the driver.

  1. Start Windows* 95.

  2. Click Start, select Settings, then select Control Panel.

  3. Double-click the Network icon.

  4. Select Intel EtherExpress PRO/10 PCI from the list of installed network devices, then click Remove.

  5. Click OK, then restart the system when prompted. If Windows 95 does not prompt you to restart your computer:

    1. Click Start.
    2. Select Shut down.
    3. Select Restart the computer.
    4. Click Yes.


  6. Return to the Network Setup dialog box in the Control Panel (as described in steps 2 and 3).

  7. Click Add, then select Adapter.

  8. Click Have disk.

  9. Insert the EtherExpress™ PRO/10 PCI diskette into drive A:, enter A:\WIN95, then click OK in the Install from Disk dialog box.

  10. Click OK in the Select Network Adapters dialog box to select the Intel EtherExpress PRO/10 PCI driver.

  11. Add or remove any additional clients, protocols, and/or services you need (if any).

  12. Click OK in the Network dialog box and allow the Windows 95 to copy the required files. Restart your computer when prompted.
G. Use Network Setup to Verify User Identification Setup

Users in the same workgroup are generally able to see each other quite easily (though sometimes it takes several minutes). It can be more difficult to see users in other workgroups. Make sure all the people on your network use the same workgroup name (unless you have a specific reason to do otherwise).

  1. Start Windows* 95.

  2. Click Start, select Settings, then select Control Panel.

  3. Double-click the Network icon, then select the Identification tab.

  4. Enter a unique Computer name for each computer on the network.

  5. Enter the same Workgroup for all computers on the network. If you want to investigate the benefits and drawbacks to using multiple workgroups on your network, consult your Windows 95 documentation.

  6. Enter a unique Computer Description for each computer or you can leave the field blank.

  7. Click OK in the Network dialog box and allow the Windows* 95 to copy the required files. Restart your computer when prompted.
H. Verify File Sharing is Enabled on at Least One Workstation

In order for others to access your computer, you must install the Windows* 95 File and Printer Sharing service. You must also select the directories or printers you want to share and configure them using the sharing option in the My Computer or Printers dialog boxes. Refer to the Windows* 95 documentation or on-line help for more information on how to share files or printers. Follow these steps to install the File and Printer Sharing service.
  1. Click Start, select Settings, then select Control Panel.

  2. Double-click the Network icon.

  3. Scroll the list of network components and look for the File and printer sharing... service.

  4. If the entry is not listed:

    1. Click on File and Print Sharing.
    2. Select the desired boxes to allow access to your files, printer(s), or both.
    3. Click OK in the File and Print Sharing dialog box.


  5. Click OK in the Network dialog box and allow the Windows 95 to copy the required files. Restart your computer when prompted.

    Note: Only those workstations with the File and Printer Sharing Service installed will appear in the Network Neighborhood dialog box. There is no reason to list workstations that have no resources to share with the workgroup. As long as a workstation can see all the stations with shared resources, the station is working properly.
I. Force IPX/SPX Frame Type when connecting to NetWare

Windows* 95 attempts to automatically determine the frame type used by your NetWare server(s). Usually Windows* 95 succeeds, but occasionally it fails. By forcing the IPX frame type you can improve your chances of connecting to NetWare servers.

  1. Determine the frame type(s) used on your NetWare server(s). Consult your network administrator to find the correct frame type for your network.
    NetWare 3.11 servers default to the 802.3 frame type.
    NetWare 3.12 and 4.x servers default to the 802.2 frame type.
    If you can access the console of the NetWare server, use the PROTOCOLS or CONFIG commands to determine which frame types are in use.

  2. Start Windows 95.

  3. Click Start, select Settings, then select Control Panel.

  4. Double-click the Network icon.

  5. Select the IPX/SPX compatible protocol, then click on the Properties.

  6. Select the Advanced tab, then select the Frame Type entry in the Property list.

  7. Change the Value to the frame type your server uses.

  8. Click OK in the Protocol Properties dialog box.

  9. Click OK in the Network dialog box and allow the Windows 95 to copy the required files. Restart your computer when prompted.
J. Start (or restart) the Computer in DOS Mode

Before using the Intel SETUP program, you must start or restart your computer in DOS mode. SETUP will not work reliably in a DOS window under Windows 95.

If Windows 95 is already running:

  1. Click on Start.
  2. Select Shut Down.
  3. Select Restart your computer in MS-DOS mode.
  4. Click on Yes.
If your computer is not turned on:

  1. Turn on the monitor and the computer.
  2. When you see the message Starting Windows* 95, hold down SHIFT and press the F5 function key. Windows* 95 bypasses the startup files and shows a DOS prompt.
K. Run SETUP to Verify Adapter Operation

The adapter diagnostics in Intel's SETUP program can give you an idea of how well your EtherExpress™ PRO/10 PCI adapter is working in your system. While passing the diagnostic tests is definitely a good sign, it is not a guarantee that your adapter will work correctly under Windows* 95. However, if the adapter fails the SETUP diagnostics, it will most likely fail under Windows* 95 as well.

  1. Start or restart your computer in DOS mode. See J. Start (or restart) the Computer in DOS Mode for details

  2. Insert the EtherExpress™ PRO/10 PCI diskette into the floppy drive, and type: A:SETUP (or B:SETUP) then press ENTER.

  3. From the Main menu of SETUP, select Test adapter then press ENTER.

  4. From the Test Adapter menu, select Test adapter then press ENTER.

  5. If the adapter failed the ONBOARD LOOPBACK test, try these suggestions:

    • Change IRQ setting (if CMOS Setup allows)
    • Avoid using IRQ 2/9 if possible.
    • Avoid using an IRQ already used by a different adapter.
    • Change IRQ settings on other adapters or disable unused ports to make IRQs available.


  6. Press the ESC key to exit the Test adapter menu and return to the Main menu.

  7. Press the ESC key to exit SETUP. Answer Yes when prompted to exit, and Yes when prompted to reboot the computer.
L. Use SETUP to View the Adapter's Configuration

If your adapter does not work correctly using the default settings, you may need to change the adapter's configuration.

  1. Start or restart your computer in DOS mode. See J. Start (or restart) the Computer in DOS Mode for details

  2. Insert the EtherExpress PRO/10 PCI diskette into the floppy drive, and type: A:SETUP (or B:SETUP) then press ENTER.

  3. Select View adapter configuration then press ENTER.

  4. Press the F5 key for the Advanced PCI Viewer.

  5. Use the left-arrow and right-arrow keys to scroll through the list of PCI devices.

  6. Press ESC to exit the viewer.
M. Remove the Dial-Up Adapter

If you install the Dial-Up adapter before the network adapter, Windows* 95 may bind the network protocols to the Dial-Up adapter instead of the network adapter. Removing the Dial-Up adapter causes Windows 95 to bind the protocols to the network adapter. If you need the Dial-Up adapter, you can reinstall it after you get the network card working.

  1. Start Windows* 95.

  2. Click Start, select Settings, then select Control Panel.

  3. Double-click the Add/Remove Programs icon, then select the Windows Setup tab.

  4. Select Communications, then click Details.

  5. Uncheck the checkbox for Dial-up Networking, then click OK in the Communications dialog box.

  6. Click OK in the Add/Remove Programs dialog box.
N. Reinstall the Dial-Up Adapter

Once you have your LAN adapter installed and working, you can add the Dial-Up if you need to access remote host systems.

  1. Start Windows* 95.

  2. Click Start, select Settings, then select Control Panel.

  3. Double-click the Add/Remove Programs icon, then select the Windows Setup tab.

  4. Select Communications, then click the Details button.

  5. Select Dial-up Networking, then click OK in the Communications dialog box.

  6. Click OK in the Add/Remove Programs dialog box.
O. Use REGEDIT to Examine the Windows* 95 Registry

The Windows* 95 registry is a database of all the hardware and software in your system recognized by Windows* 95. Using the REGEDIT program, you can verify that your network adapter settings are correct.

WARNING: REGEDIT immediately saves the changes when you make them, and there is no UNDO feature. Be very careful to change only those settings you intend to change. Accidentally deleting or changing the wrong information may make it necessary for you to reinstall Windows 95.

  1. Start Windows* 95.

  2. Click Start, then select Run.

  3. Enter REGEDIT, then press ENTER.

  4. In the left-hand side of the REGEDIT dialog box, open each of the following folders:

    - HKEY_LOCAL_MACHINE
    - System
    - CurrentControlSet
    - Services
    - Class
    - Net

  5. Under the Net folder, you should see one or more sub-folders named with 4-digit numbers. The quantity of numbered sub-folders under the Net folder should match the quantity of adapters shown in the Network setup dialog box. For example, if you saw only the Intel® EtherExpress™ PRO/10 PCI adapter in the Network Setup dialog box, you should have only 1 numbered sub-folder. If you saw the Intel® EtherExpress™ PRO/10 PCI adapter and the Dial-Up adapter in the Network Setup dialog box, you should see two numbered sub-folders.

  6. If you have too many sub-folders:

    1. Close the REGEDIT window.
    2. Open the Network setup icon found in the Control Panel.
    3. Remove all adapter drivers. This will also remove all clients, protocols and services.
    4. Go back to REGEDIT and make sure the Net, NetClient, etServices, and NetTrans folders are completely empty (no plus symbol to the left of the folders).
    5. Exit the registry editor and restart Windows* 95.
    6. Reinstall the driver for your adapter.
    7. If your adapter still does not work correctly after reinstalling, continue with the next step.


  7. Select the 4-digit folder number and find DriverDesc in the Name column of the right-hand side of the REGEDIT dialog box. Just to the right of DriverDesc, you should see Intel® EtherExpress™ PRO/10 PCI. If not, select the next numbered folder.

  8. After finding the folder for the EtherExpress adapter, locate DeviceVxDs in the Name column in the right-hand side of the REGEDIT dialog box. Just to the right of DeviceVxDs you should see "e10p.sys".

  9. If the filename is missing or incorrect:- Double-click the left Typee10p.systhen press ENTER (or click OK).

  10. Close the REGEDIT window and restart your computer.
P. How to Disable the Autologon Feature in Windows* 95 Disabling the Autologon feature in Windows* 95

In order to enable the network login prompt, you must first disable the "Autologon" capability in Windows* 95.

The following procedure uses "Regedit", which can be extremely harmful to your system. Follow these instructions exactly.

Instructions:

  1. Click on Start.
  2. Click on Run
  3. Type REGEDIT
  4. Click Edit
  5. Click Find
  6. Type 'autologon' and hit <ENTER>
  7. 'autologon' will appear, and be highlighted. hit <ENTER>
  8. You will see a window appear with numbers in it BE VERY CAREFUL!
  9. Hit the delete key on the keyboard 1 time only.
  10. Type '00' (that is the zero not the letter 'O'.)
  11. Hit <ENTER>
  12. Click on Registry
  13. Click on Exit
You are finished!
-Again, please be very careful using REGEDIT. Do not use it unless you have clear-cut instructions on what to do.
