All you are doing is building the same kernel as you now have, except, you will enable drivers that you currently do not have in the vanilla Fedora kernel, because the drivers you want are in the "staging" area, and thus are not automatically built for distribution. You will skip the parts where you need to copy the old kernel tree to .org, ....etc You will not be inserting new source modules and you will not be building your own modules. What I will do is copy and paste exactly the steps that YOU need to do in order to build your kernel with your device enabled. 01. su -c 'yum install rpmdevtools' 02. cd ~ 03. rpmdev-setuptree 04. yumdownloader --source kernel 05. sudo yum-builddep kernel-2.6.34.7-61.fc13.src.rpm If you do not have sudo permission, then you have to know the super user password and do su -c 'yum-builddep kernel-2.6.34.7-61.fc13.src.rpm' 06. cd ~/rpmbuild/SRPMS 07. rpm -Uvh kernel-2.6.34.7-61.fc13.src.rpm 08. cd ~/rpmbuild/SPECS 09. rpmbuild -v -bp --target=`uname -m` kernel.spec 10. cd ~/rpmbuild/BUILD/kernel-2.6.34.fc13/linux-2.6.34.i686* 11. cp configs/kernel-2.6.34.7-i686-PAE.config .config 12. make oldconfig 13. make xconfig This will pop up the cong GUI. Scroll the left column of the GUI all the way down. In the middle of the page you will see Staging Drivers It is a small print with an empty square on it's left. Click the square so it shows a check mark. 14. On the right side of the GUI you will see the selection for RealTek RTL8192E Wireless LAN NIC driver (RTL8192E) with a tiny square on it's left. Click the square so it shows the check mark. 15. If this is all you need as far as drivers, then click on the dark square icon under the tab "Option". That will save the .config file. 16. Click File->Quit 17. cp .config ~/rpmbuild/SOURCES/config-i686-PAE 18. cd ~/rpmbuild/SPECS 19. rpmbuild -v -bb --target=i686-PAE kernel.spec After the build finishes, it will show you that it built, among other other variants of the kernel, /home/YourDir/rpmbuild/RPMS/i686/kernel-2.6.34.7-61.fc13.i686-PAE.rpm Now, installing the newly built kernel is just a matter of: 20. rpm -Uvh --nodeps --force /home/YourDir/rpmbuild/RPMS/i686/kernel-2.6.34.7-61.fc13.i686-PAE.rpm Reason I used --nodeps --force is because I am just not sure whether or not the rpm command will bitch at you, since you already have this version of the kernel already installed. 21. Reboot. Your device will be recognized.
