knoppix iso for archive

[Roger Searle]

Hi Christopher - the knoppix ISO I have downloaded for the linux 
archive, exceeds the 4BG size that k3b will burn to a disk, though small 
enough that it could fit on a DVD (no doubt there is some issue I know 
nothing about regarding the size of files that can be burnt).

The question is, do you particularly want to get this as an ISO?  If so, 
is the USB2 port installed yet?   Or is in the form of a bootable DVD OK?

Or, in the absence of a USB2 port, perhaps there is some clever trick 
that will let me burn this ISO to DVD via that magical command line? If 
so, what might that magic be?

Cheers,
Roger
