This is a terribly difficult network card to load. I attempted to use the install files included - it didn't work. I attempted to use the win2k_9x (available on Driverguide), also didn't work. I unzipped this file to a disk, then I removed all the old files from failed attempts, reinstalled the hardware and rebooted system (a fresh start). I then plugged in files as requested from this package of files and several .dll files in my Windows files. It wasn't easy, but it worked! Good Luck.
