You can boot from the CD and install it to a "normal" hard disk using slitaz-installer. Then refer to the documentation here:
http://doc.slitaz.org/en:handbook:hacklivecd
You'll have to replace the kubrick/resources/devices/k5/{main_kernel,main_partition.gz} files in the CD's root ("rootcd" folder), then re-build the ISO using tazlito gen-iso.
The commands that you need are described in the link I gave above; the kernel and partition can be downloaded from one of the mirrors in the "simple debricking" thread.
