knoppix

[JB]

I downloaded knoppix and burned a cd but it won't
boot.
I switched the bios to boot the cd drive first and
then the floppy but that shouldn't matter. I'm not
sure if I burned it wrong or what the deal is. At the
knoppix website it says you can make a boot disk from
a boot img on the disk but I looked at he disk and it
is just the whold iso image. Did I burn the disk
wrong?
Any suggestions would be appreciated.
Thanks in advance.
