Maybe the fedora core 3 could be a choice if your are not very familiar with linux...
But before go to fc3, you should try a couple of things, to see if you can manage to put your wireless card up!
First, you should do the command "lspci", and check if your wireless card pears there... otherwise, you have to upgrade your system! And maybe before the next steps... you should install fc3...
If ok... the next step (and admiting that you can will ndiswrapper, the program that uses the windows drivers), you should download one of the latest versions of ndiswrapper (one advice... choose the second or third newer one...).
You compile ndiswrapper (just doing "make install" after decompress it, always as root).
After this... you should know where you have your windows drivers... the directory in the windows partition... or just copy the .inf file for a specific place, but remember that place (ndiswrapper should require more files... but you just put all that files, asked by ndiswrapper, in the same folder and it should work!).
ok... The next step... "ndiswrapper -i <path_to_the_file/<driver_name>.inf>"
After this step you should get an info, saying that the driver has been installed, and the hardware is present on the system... you can see it by typing "ndiswrapper -l"...
If everything goes ok until here... just do "ndiswrapper -m" to install the ndiswrapper module, for future use... and to finalize "modprobe ndiswrapper"!!
After this... you should have some result in this command "ifconfig"... something like wlan0... that is you wireless interface!!
Ok... I think as a first try this could be sufficient... but keep contact... and say how is it going!
See you around!
