Salman, The Ethernet HOWTO has lots of information on the 3COM cards (including the 3c905B) and how to make them work under Linux. http://www.linuxdoc.org/HOWTO/Ethernet-HOWTO.html I do have a 3C905B and a second card installed and operating just fine in a 733MHz Pentium system connected to a cable modem. I was able to get them working by following the info in the HOWTO. Regards, T. Tilton
