Boot Live CD using a flash drive?

I know it's possible to boot the Knoppix CD using a diskette, but how can I boot it using a flash drive?

I am unable to boot using a diskette or a CD at my school yet I am able to boot using a USB Flash drive. Could someone explain how I could do this?

Thanks in advance.

It's easy. Step by step instructions, with pictures, are posted at: www.tuxmachines.org/node/14738

Took me about 12 minutes to do, following his instructions.
