UMAX ETHERNET DRIVER

Go to the vendor's web site, search there based on your model.

Although from I can see, the last drivers for anything on Umax is from before 1990 and the links are dead. May need to run a program to tell you exactly what hardware is in the system and do a search based on the motherboard brand and model, unless the network card is separate from that. This should get you some info. http://www.piriform.com/speccy/download/standard
