I am working with 2.6.11-1.1369_FC4 and I should like to install also a vanilla kernel in the same HD.

I have the linux-2.6.15.tar.bz2 and patch-2.6.15.bz2 files.

I think I must compile the kernel but:

How can I patch the linux kernel?
How must the HD be prepared before compiling?.
The boot loader is Grub. How must it be modified to start in Fedora or in Linux?

I know they are too many questions for a forum, and maybe this is not the best place to ask them, but any information will be appreciated.

Saludos.

I'm sorry I don't know anything about patching kernels, and I'm pretty sure it's done before installation, but to install the kernel do this:

1. Unzip the Kernel archive (linux-2.6.15.tar.bz2)
2. Move the folder (linux-2.6.15) to /usr/src/kernels (If you have the kernel-devel package installed you should see the folder of the old kernel)
3. Enter the folder in a root terminal and execute the following command:

You'll get a graphical interface for choosing kernel modules and drivers. With this you choose what hardware to support, or to remove support for different things (you'll find lots of internet sources for this). WARNING: Don't do anything you're unsure of here.

When you're done, do the following:

This should take quite a while. If all goes well and no errors occur, simply reboot and you should find the new kernel as an option in grub. It's done automatically. If anything goes wrong (Kernel panic or whatever), you can reboot into the old kernel at any time for troubleshooting.

You have the kernel source file linux-2.6.15.tar.bz2 so the patch-2.6.15.bz2 file is not needed.

It would be better to;

cp /boot/config-2.6.11-1.1369 .config (a starting point so you)
make xconfig (can customize the kernel here a little bit quicker)
make && make modules_install && make install

If you never built your own kernel before, may I suggest that you read;

You have clarified all the asked questions.

Thank you very much everybody!
