Installing a windows driver with ndiswrapper isn't that hard. Here is some simplified instructions:
1. Make sure you have the kernel sources installed. On the fedora cd it is called the kernel development packages.
2. Download ndiswrapper:
http://prdownloads.sourceforge.net/ndiswrapper/ndiswrapper-1.0.tar.gz?download
3. Extract ndiswrapper with the following command-line statement:
tar -zxvf <whatever your file is called.tar.gz>
Just put the filename.tar.gz of ndiswrapper after the -zxvf
4. cd <ndiswrapper directory>
When the files get extracted see which folder was created.
5. su
Enter your root password when prompted
6. make
7. make install
8. Go to windows and download the driver for the the card:
http://www.giga-byte.com/Download/Download.asp?DownloadPath=/Communication/FileList/Driver/wpeag.v.3.1.2.21.02.zip
9. Unzip the file.
10. Find the .inf and .sys files and put them on a floppy or whatever to transfer them over to linux
11. Go back to linux and copy over the files into a directory. You can create a directory by doing:
mkdir <directory name>
12. type:
su
enter root password when prompted
12. Enter that directly and type the following:
ndiswrapper -i <filename.inf>
followed by
ndiswrapper -l
13. add the following lines to /etc/modprobe.conf
options ndiswrapper if_name=eth0
alias eth0 ndiswrapper
13. type:
modprobe ndiswrapper
14. type:
dhcpcd eth0
15. At this time you should be able to connect to the internet. If not try adding eth0 in the fedora network configurations located in the systems menu or somewhere around there.
16. If all is good run this command:
ndiswrapper -m
17. Finally add the following line in /etc/modules.conf (I think that's what it is called in fedora)
ndiswrapper
