# How to temporarily boot with a different kernel

If you want to permanently replace the kernel please see [here](kernel.md).

First go [here](http://distro.ibiblio.org/fatdog/kernels/) and
download vmlinuz-x.x.x and kernel-modules.sfs-x.x.x,
where x.x.x is the kernel version that you want.
Vmlinuz is the actual kernel and kernel-modules.sfs contains the
kernel modules (drivers) that are built to work with it.
Keep the names, you don't have to rename it (although you can if you want to).

Then, in in your bootloader (say grub), add an entry that point to that
new kernel. Also, as part of your boot parameters, specify
**extrasfs parameter** that points out to the downloaded kernel modules.

Then boot. It's that simple.

If you only want to do this one time, you can enter into grub during
booting stage, and edit the grub lines yourself.
Nothing is changed, and on next boot you will get back to your usual kernel.
