Hi,

You'll need to boot from the cdrom, on the 6100 you can do this in three different ways.

- acces the bios (press esc repeatedly during boot when you see the "Toshiba in touch with tomorrow" logo)
you'll get press F1 for setup, set bootup sequence to cdrom

- press F12 a few times during the bootup (when you see the logo)
then simply select the cdrom logo

- press the left or right cursor a few times during the bootup.
then simply select the cdrom logo

I've been using Knoppix on the 6100 for a couple of years and it works perfectly, install goes well (3.6 through 4.02)
