# First of all, prepare an initramfs for testing the RTAI kernel, modules,
# and applications. Since RTAI only works on x86, create an initramfs for x86.
# This can be done by using some scripts from the ramfs-scripts.tgz
# package (which do not use busybox and do not recompile anything: they just
# copy files from your filesystem to the initramfs

tar xvzf ramfs-scripts.tgz
cd mkfs
./mktestiniramfs.sh

# Now, uncompress the kernel and RTAI
tar xvjf ~/src/RT/DualKernel/linux-2.6.19.7.tar.bz2
tar xvjf ~/src/RT/DualKernel/rtai-3.5.tar.bz2

# Patch and compile the kernel
cd linux-2.6.19.7
