in that case a dvd+rw would be great, you can fit knoppix on that and still have room otoh i do not know if it can be run on that as a hddinstall. it might. hmmmm.
if you do the "poormans install (that is put the knoppix.iso on the dvd) and boot from a floppy it might work.
and if then the making of a persistent /home on the dvd works you have a semi-permanent solution.
it would just cost a few € to replace the whole disk (if it crashes). and it could be blanked a few times (iirc 12 full formats).
she would still have some 3Gb to save things to...

aaarrrgghhh, thoughts running in circles.
i MUST try. have to wait till i get this months paycheck though, i have no internal dvdburner, have a firewire/usb2 external. would require a boot os on hdd to get THAT going. hmmm. must try, frustrating to have to give blind advise.

aaaarrrrgggghhh.
could someone please try and report?. i am getting frustrated here.
