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.
