Re: Kernel Source - Fedora Core 3

Hi Mark,

the driver should work with FC3, so hopefully you will be able to fix
the problem.

In my opinion, Jörg please correct me if I am wrong, the Fedora Core 3
kernel is missing the wireless lan extensions. Without those you are
still able to build the module against the kernel but you can't load it.

Without the right symbols in your kernel the module does not work. So
there are two possibilities. Either you get the people who are making
the rpm-files for FC3 to include the necessary options or you have to
build the kernel by yourself. This is not a hard thing to do. It
involves a little bit of knowlegde and is not as plug&play like
installing the default kernel but on the other hand enables you to tune
the kernel to your specific system. There should be plenty of help on
the web how to do this.
