One place you can get the knoppix config/patches is from /usr/src on Knoppix cd. It seems a bit silly downloading a whole CD just to get the patch, but I'm not sure where else to get it
You can get not only that patch but also the Knoppix .config in the kernelsources.dsl in the dsl repository.Here is a step by step kernel recompile. I did this in Debian, because that happens to be my distro of choice.
You need the kernel-source, cloop-source, dsl*.iso, and the kernel-source.dsl from the repository.
I will assume you have all the dependencies for compiling a kernel. With debian you can do apt-get builddeps kernel-package to get everything you need.
I used 2.4.31 from http://kernel.org. I couldn't find the cloop sources so I got them from my debian repositories apt-get install cloop-src. Downloaded the dsl package from the dsl rearpository.
# make a directory to work with mkdir ~/dsl export dsl_work_dir=~/dsl cd $dsl_work_dir
# rename dsl package because gzip is too smart for its own good. mv kernelsource.dsl kernelsource.tar.gz
# extract you kernel-sources tar jxvf linux-2.4.31.tar.bz2
# extract kernelsource dsl tar jxvf kernelsource.tar.gz
# The debian package of cloop-src installed in /usr/src # lets get it into our dir cp /usr/src/cloop.tar.gz $dsl_work_dir
# and extract it tar -zxvf cloop.tar.gz
# copy dsl .config to out new sources cp usr/src/linux/.config linux-2.4.31/
# go into our kernel-source dir cd linux-2.4.31
# configure kernel make oldconfig
# If you need to make any changes now it the time to do it. # You shouldn't need to and if you are reading this, you # probably shouldn't do it any way, but its here for completeness make menuconfig
# Our kernel is now ready to compile make dep; make bzImage; make modules
if [ ! -d ../modules ] && mkdir ../modules
# There is probably a better way to do this, but I don't know it sudo make modules_install cp /lib/modules/2.4.31 ../modules/ sudo rm -rdf /usr/src/2.4.31
# If you made it this far without errors, have a cookie # now on to the cloop module # this assumes you used the debian package it extracts to # modules/cloop which we extracted in $dsl_work_dir cd $dsl_work_dir/modules/cloop make $KERNEL_DIR=$dsl_work_dir/linux-2.4.31 cd $dsl_work_dir
# lets extract our iso mkdir iso_source sudo mount dsl-1.1.iso /mnt -o loop cp -a /mnt/* $dsl_work_dir/iso_source/ umount /mnt
# This assumes that you have cloop up and running on your current system, if not you can do this with dsl by adapting the remastering howto. sudo /sbin/modprobe cloop file=$dsl_work_dir/iso_source/KNOPPIX/KNOPPIX mkdir KNOPPIX sudo mount /dev/cloop0 ./KNOPPIX cp -a modules/2.4.31 ./KNOPPIX/lib/modules/ rm -rdf ./KNOPPIX/lib/modules/2.4.26 umount ./KNOPPIX sudo /sbin/modprobe -r cloop
# KNOPPIX file is done, onto the minirt.gz cd iso_source/boot/isolinux gunzip minirt.gz mkdir tmp sudo mount minirt tmp cd tmp/modules cp $dsl_work_dir/modules/cloop/cloop.o ./ cd ../../ sudo umount tmp/ rmdir tmp/ gzip minirt
# lets replace out kernel cp $dsl_work_dir/linux-2.4.31/arch/i386/boot/bzImage ./linux24
cd $dsl_work_dir
Now you just need to make the iso, burn and boot it. mkisofs -no-pad -l -r -J -no-emul-boot -boot-load-size 4 -boot-info-table -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat -hide-rr-moved -o newdsl.iso iso_source
There are probably numerous errors, this was adapted from a usb pendrive method from memory and my memory isn't that great, I will update it if anyone finds any errors.
