FIXME //First work by VERHILLE Arnaud  copyright FDL //

Boot on the knoppix CD then
===== Put the whole Knoppix filesystem on HD =====
<code>
su -
mount -o rw /dev/hde2 /mnt/hde2
mkdir /mnt/hde2/knx
mkdir /mnt/hde2/knx/source

mkdir /mnt/hde2/knx/master
mkdir /mnt/hde2/knx/source/KNOPPIX
mkdir /mnt/hde2/knx/master/KNOPPIX
cp -Rp /KNOPPIX/* /mnt/hde2/knx/source/KNOPPIX
</code>

===== Get 1Go of virtual Memory =====

Create a 800Mbyte file :
<code>
dd if=/dev/zero of=/mnt/hda6/swapfile bs=1024 count=800k
mkswap /mnt/hda6/swapfile
</code>
Activate swap
<code>
swapon /mnt/hda6/swapfile
</code>
Destroy swapfile
<code>
swapoff /mnt/hda6/swapfile
rm -rf /mnt/hda6/swapfile
</code>

Now you can

===== Chroot Knoppix filesystem =====
<code>
xhost + 127.0.0.1
su -
umount /mnt/hde2;mount -o rw /dev/hde2 /mnt/hde2
chroot /mnt/hde2/knx/source/KNOPPIX/
mount -t proc /proc proc
export DISPLAY=127.0.0.1:0
</code>

===== Configuring Internet access =====
<code>
joe /etc/resolv.conf
</code>
Add at the end of the file :

</code>

/home/knoppix files should put here : /etc/skel

Add CUPS initialization : /usr/bin/configure_printer

Last configuration can be put in : /knx/master/KNOPPIXConfig.tar.bz2

===== How-to build a debian .deb =====

umount /proc
then press Ctrl-D
rm -rf /mnt/hde2/knx/source/KNOPPIX/var/tmp/*
rm -rf /mnt/archive/knx/source/KNOPPIX/root
mkdir /mnt/hde2/knx/source/KNOPPIX/root
</code>

===== Modifying Boot Screen =====

    a) Boot logo
logo.16 is the image displayed on boot screen.  It is encoded in a special format. For replacing it grab a 640*400  16 color image. I downloaded an image from gnu.org. Convert the image to a png file ( call it logo.png) 

 
#pngtopnm <logo.png >logo.pnm
#ppmtolss16 <logo.pnm >logo.16
#cp logo.16 /mnt/hda3/image/logo.16 
   
  (Keep the size of the final log.16 around 50 k). Unmount image directory. Copy the boot.img to a floppy
   #dd if=boot.img of=/dev/fd0
Boot the machine from the floppy you have made. If it boots up properly you are done 

===== Build a bootable knoppix CD iso =====
<code>
cp /mnt/hde2/knx/source/KNOPPIX/usr/bin/create_compressed_fs /usr/bin/
</code>

==== Methode 1 ====
<code>
cd /mnt/hde2/knx/source/KNOPPIX; mkisofs -R -V "KNOPPIXFS" -P "KNOSCIENCES" ./  |  create_compressed_fs - 65536  > /mnt/hde2/knx/master/KNOPPIX/KNOPPIX
</code>
==== Methode 2 ====

<code>
cd /mnt/hde2/knx/source/KNOPPIX ; mkisofs -R -U -V "KNOSCIENCES" -publisher "GISTLABS" -hide-rr-moved -cache-inodes -no-bak -pad ./ | nice -5 /usr/bin/create_compressed_fs - 65536 > /mnt/hde2/knx/master/KNOPPIX/KNOPPIX
</code>
==== Build final iso ====
<code>
cd /mnt/hde2/knx/master/; mkisofs -pad -l -r -J -v -V "KNOSCIENCES" -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat -hide-rr-moved -no-emul-boot -boot-load-size 4 -boot-info-table -o /mnt/hde2/knx/Knosciences_tmp.iso /mnt/hde2/knx/master
</code>
==== Burn iso ====
<code>
cdrecord -v speed=24 dev=0,0,0 /mnt/hde2/knx/Knosciences_tmp.iso
</code>
