I want to run the BackTrack 3 Live CD on my new Eee PC 901. Here is how I configured a SD card to boot the BackTrack 3 USB Version (not the same as installing the BackTrack 3 distro on a SSD or SD card).
- start Windows XP on Eee PC
- download the BackTrack 3 USB version
- use unetbootin to install the BackTrack 3 iso file to the SD card
- copy 901_net_gfx.lzm to the \BT3\optional directory on the SD card (details and download here)
- edit file /boot/syslinux/syslinux.cfg on the SD card to add these lines after the LABEL… line:
LABEL EEE MENU LABEL BT3 EEE Mode KERNEL /boot/vmlinuz APPEND vga=785 initrd=/boot/initrd.gz ramdisk_size=6666 root=/dev/ram0 rw load=901_net_gfx autoexec=startx
The following step is only needed if you want to change the keyboard. I use a Belgian keyboard, so I want the default KDE keyboard to be the BE keyboard, not the US keyboard. We will update the kxkbrc file in the root.lzm compressed directory. sda1 is the SD card I booted from, adapt according to your configuration.
- Boot BackTrack 3 from the SD card and get a root shell
- cp /mnt/sda1/BT3/base/root.lzm .
- mv /mnt/sda1/BT3/base/root.lzm /mnt/sda1/BT3/base/root.lzm.original
- mkdir newroot
- lzm2dir root.lzm newroot
- edit file newroot/root/.kde/share/config/kxkbrc
- edit the LayoutList property and move the be value to the beginning of the comma-separated list, like this:
- LayoutList=be,us,ch,br,cz,fr,de,it,pl,sk,gb,dk,de
- save file kxkbrc
- dir2lzm newroot root.lzm
- mv root.lzm /mnt/sda1/BT3/base
You can use the same procedure to edit other (config) files, or add files like your favorite utilities.

it’s easier to put the changed kxkbrc into the (new) directory BT3/rootcopy/root/.kde/share/config.
