LinuxDevCenter.com: Using and Customizing Knoppix [Nov. 20, 2003]: "Copy the contents of the compressed kernel image from the CD. Mount the file /KNOPPIX/boot.img on a loop device and copy the contents from the device to /hardrive_boot/. I used these commands:
bash-2.05# /sbin/losetup /dev/loop0 /mnt/linux1/KNOPPIX/boot.img
bash-2.05# mount /dev/loop0 /mnt/floppy/
bash-2.05# cp /mnt/floppy/* /mnt/linux1/hardrive_boot"
