this is copied from a Knoppix remastering howto I once read, don't blame me if it doesnt work.

Modifying Boot Screen

The Knoppix Cd uses syslinux to boot. If you want to change the boot screen/messages do the following. Make a temporary directory on your hard disk (I did mkdir /mnt/hda3/image)
Copy the boot.img file from Knoppix directory of your knoppix cd
#cp /KNOPPIX/boot.img /mnt/hda3
Mount the image as follows
# mount -t msdos -o loop /mnt/hda3/boot.img /mnt/hda3/image
Now look in the image directory you created. There are a number of interesting files in this directory
a) Boot logo
logo.16 is the image displayed on boot screen. It is encoded in a special format. For replacing it grab a 640*400 16 color image. I downloaded an image from gnu.org. Convert the image to a png file ( call it logo.png)

#pngtopnm <logo.png >logo.pnm

#ppmtolss16 <logo.pnm >logo.16

# cp logo.16 /mnt/hda3/image/logo.16

(Keep the size of the final log.16 around 50 k). Unmount image directory. Copy the boot.img to a floppy
#dd if=boot.img of=/dev/fd0
