I have an old Pentium I 133MHz and I'm going to run it as a firewall on my network. I've installed many of network cards before but I have never had a problem installing them. For some reason it doesnt seem to fit. Are there different types of network cards or am I just going crazy over here. I bought the Linksys 10/100 LAN CARD Network Interface Card for Desktop Computers. Minimus Requirements(which of course I didnt read) Pentium Class 200Mhz. Should I be looking for something else? I'm also running Mandrake 9.0 if it makes any difference.
