HD Install :: cheatcodes tohd and fromhd not working

I'm trying to run DSL 2.0 as Live-System from my Hard-Drive.

No succes so far.

When I tried the cheatcode:
tohd=/dev/hdb1
on this ext2-partition the Folder KNOPPIX with the KNOPPIX-Image is copied as expected.

When rebooting with CD using the cheatcode
fromhd=/dev/hdb1

linux24 and minitrd.gz is loaded, but then I get the error
"can't find Knoppix Filesystem"
and a mini-Linux is presented.

Any Ideas?

Does it work if you try it without the "fromhd" code?

Sometimes it can find the KNOPPIX filesystem if you don't tell it where to look.

strange enough, this entry in my grub menu starts the DSL System with "Live-Modus":

Code Sample

#line 39, manual added for usb-stick boot
title DSL_Test
kernel (hd0,7)/boot/isolinux/linux24 ramdisk_size=100000 init=/etc/init lang=de
initrd (hd0,7)/boot/isolinux/minirt24.gz

In fact: it does a automtic search(!) and doesn't wonder about the fact, that the image isn't found on a CD-Rom.
