The information in this article applies to:

  • Microsoft Windows 95

This article was previously published under Q164738

SYMPTOMS

When you are performing a shared installation of Windows 95 using an IBM Token Ring Auto 16/4 ISA network adapter, Windows 95 may not connect to the network during the real-mode to protected-mode network transition.

CAUSE

IBM Token Ring Auto 16/4 ISA network adapters with a microcode level 000700 PP1FA7 have a Plug and Play BIOS that cannot be disabled using the Lanaid.exe configuration tool supplied by IBM.

RESOLUTION

You must disable the network adapter's Plug and Play BIOS in order for the network transition to be successful.

Contact IBM Corporation for more information about this procedure.

MORE INFORMATION

In a local installation of Windows 95 with this adapter at this microcode level, the results are that two IBM Token Ring Auto 16/4 ISA network adapters are enumerated and listed in Device Manager. One of the devices is listed as not working. Removing either device prevents the network adapter from working properly; and on reboot the device is enumerated and listed twice in Device Manager again.
