NE2000 and Panasonic CD-ROM Fails when Used Simultaneously

- Microsoft Windows NT Workstation version 3.5 - Microsoft Windows NT Server version 3.5

SYMPTOMS

You experience a failure loading and simultaneously using a NE2000 (or compatible) network adapter and a Panasonic CD-ROM drive attached to a Sound Blaster 16 adapter.

CAUSE

This problem occurs when the NE2000 (or compatible) network adapter is configured to use an I/O port address greater than 300H.

RESOLUTION

To correct this problem, do one or both of the following:

• Configure the I/O port address of the NE2000 (or compatible) network adapter to less than 300H. The NE2000 driver shipped with Windows NT version 3.5 only supports the I/O port address of 280H under 300H. To change the address setting, do the following:

  1. Run Control Panel and choose Network.

  2. Select the NE2000 driver under Installed Adapter Cards and choose

        Configure.
  

  3. Change the I/O Address to 280H and choose OK.

  4. Shutdown Windows NT.

  5. Either run the Configuration Utility or change jumpers on the NE2000

        (or compatible) network adapter, configuring it to use the I/0 Port
        address of 280H.
  

  6. Restart Windows NT.

• If the I/O port address of 280H does not work, change it to a another one either by using the Configuration Utility or changing the jumpers on the network adapter. In Windows NT, you must modify the Registry to change to an address other than 280H.

  WARNING: Using Registry Editor incorrectly can cause serious, system- wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

  1. Run Registry Editor (REGEDT32.EXE).

  2. From the HKEY_LOCAL_MACHINE subtree, go to the following key:

           SYSTEM\CurrentControlSet\Services\NE2000x\Parameters
  
        (where x is the number of the NE2000 network adapter)
  
     3. Select the IoBaseAddress value.
  
     4. From the Edit menu, choose DWORD.
  
     5. In the Data field, type the hexadecimal address configured for the
        network adapter. For Radix, select Hex.
  
     6. Close Registry Editor.
  
     7. Shutdown and restart Windows NT.
