ok well first that is the correct YUM statement if ndiswrapper is in your repo.
If you have rpmforge in your repo then you should be fine.
What you now need to do for ndiswrapper is go and get the windows EXE for your wireless card and extract it
for that you have a couple of options
First there is WINE, if you have it installed run the EXE in wine and change where it extracts to a more convienent place.
Second if you dont like that you can try a program called cabextract
third you can try the following code which might work depending on how you have fedora setup
I also sometimes save myself time if i have quick access to a windows machine and extract the files to a flash drive.
In any rate, the next thing you do is point ndiswrapper at the .inf file i believe
for my card the code looks like this
Code:
ndiswrapper -i /home/$USER/drivers/bcm5wl.inf
give this a whirl and let me know how it turns out
additionally here is the
link to ATI 32 bit drivers for the 3XXX cards for linux. They also have the 64 bit version. I havent tried these due to only buying nvidia but i would assume this should work
