Event ID 5012 Occurs with 3C589 PCMCIA Network Card (141715)


The information in this article applies to:

  • Microsoft Windows NT Workstation 4.0
  • Microsoft Windows NT Server 4.0
This article was previously published under Q141715

SYMPTOMS

When you upgrade or perform a new installation of Windows NT Workstation or Windows NT Server with a 3Com EtherLink III (3C589B) adapter, Setup may not correctly detect the settings for the network interface card (NIC). If you continue with the installation and do not verify the settings, the following error message may appear when you start your computer:
At least one service or driver failed during system startup.

The following event is logged in the system log:

Event: 5012.
Source: ELNK3
Description:

ELNK31: The I/O base address supplied does not match the jumpers on the adapter.

CAUSE

This is caused by the driver not automatically setting the Bus Type and Card Type for PCMCIA during the installation. During Setup, it defaults to ISA Bus Type.

RESOLUTION

Reconfigure the 3C589 driver in Control Panel by choosing Network so the Bus Type is set to PCMCIA. You may need to modify the registry to ensure the Card Type and PCMCIA are enabled properly.

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\Elnk31\Parameters
  3. From the Edit menu, select Add Value.
  4. Add the following:

    Value Name: Pcmcia
    Data Type: REG_DWORD
    Data: 1
  5. Modify the following:

    Value Name: CardType
    Data Type: REG_DWORD
    Data: 0x3 (Select hexadecimal radix)
  6. Choose OK and quit Registry Editor.
  7. Shut down and restart Windows NT.
If the system has a docking station network card different from the PCMCIA card, set the IRQ for the 3C589 to the following if the system locks up when inserted in the docking station: 
   3C589:
      IRQ: 7
      Base Address: 0x320

   Default settings for second NIC:
      IRQ: 10
      Base Address: 0x300
