Additional Notes
I have a 3Com Network card in one of my computers and it is an older computer so I loaded 98 on it. And when I did the driver was recognized by windows but it couldnt install it completely, and after 3 or 4 days of extensive internet searching, I found a mirror off of a german site to download this driver that made the network card work. it is for the 3C90X models. If you have a 3Com NIC and its model number is 3C90X model and not working properly, this driver should hook you up phat.
