Note: This is just groundwork and is nothing more than JavaScouts quick guide to his patch set ATT.

Plenty of other people have already written how to's. You must have udev installed or the 2.6 kernel will not work. Check out this page on Migrating to the 2.6 kernel. Other useful pages are How to apply a kernel patch and this article on compling a kernel

Basically its

cd /usr/src
tar xvjf linux-2.6.15.tar.bz2
cd linux-2.6.15

Note: The following patch does not work with the standard Kurobox. Use the patch located at for the standard Kurobox.


Whatever patch you use, you need to unzip it and apply it.

bunzip2 kurobox-sources-2.6.15.patch.bz2
patch -p1 < kurobox-sources-2.6.15.patch

Next we need to configure the kernel. There is a basic configuration with each patch. for the Kurobox HG do this:

cp config_kuroboxhg .config

For the standard Kurobox do this:

cp config_kurobox .config

If you want to use the standard kernel type this:

make oldconfig

If you want to customize your kernel type this:

make menuconfig

Make the kernel and make and install the modules

make vmlinux modules modules_install

Loader.o needs a binary of the new kernel. We'll convert our new kernel and put the new kernel in /boot

objcopy -O binary vmlinux /boot/vmlinux-2.6.15-kurobox

Change to /boot

cd /boot

If you don't have a copy of loader.o in /boot you should download a copy from the Gentoo downloads area


Sync the drive, load the kernel into memory, and jump to the new kernel.

sync;insmod loader.o kernel=vmlinux-2.6.15-kurobox
