Any way to boot Knoppix entirely off NTFS partition?

With a stanza like the following in GRUB...

# For booting Knoppix off the hard disk
title Boot Knoppix 3.4 from hard disk
kernel (hd0,0)/KNOPPIX/linux26 \
     bootfrom=/dev/hda1/KNOPPIX/KNOPPIX.iso \
     lang=us keyboard=us alsa
initrd (hd0,0)/KNOPPIX/minirt26.gz

...one can boot from KNOPPIX.iso off an NTFS partition (given that 
KNOPPIX.iso, linux26, and minirt26.gz are in C:\KNOPPIX).  However, it 
still requires the Knoppix CD to be in the drive.

I've been playing around with various combinations of the 
"knoppix_dir=", "knoppix_name", and "fromhd=" cheatcodes (in GRUB's 
"kernel" statement), trying to get Knoppix to run *entirely* from the 
hard drive, without needing to access the CD, with no success.

Has anyone made it work?
