USB booting :: Grub4Dos & DSL



I am trying to add the new DSL 3.1 to my USB-stick where I can boot Dos & BartPE without any problems from the Bootmanager Grub:

-> I downloaded the dsl-31.iso and unpacked the content
-> copy Directory /boot/isolinux to stick (root)
-> copy Directory /knoppix to stick (root)

Then I tried to modify the menu.lst
but can't get it to work.

I tried these here:
1. chainloader /boot/isolinux/isolinux.bin

2.
find --set-root /boot/isolinux/isolinux.bin
chainloader --force (cd)/boot/isolinux/isolinux.bin

3.
kernel (cd)/boot/isolinux ramdisk_size=100000 init=/etc/init lang=us apm=power-off vga=791 nomce quiet dma screen=1600x1200
initrd (cd)/boot/isolinux/minirt_usb6.gz
boot
-> error while parsing number
4.
I tried also booting with the bootimage bootfloppy-usb.img
-> doesn't work
I modified the img and copied from DSL /boot/isolinux the files to the image, but can't copy the (new) minirt24.gz to the image, because it's only 1,44MB
I succeeded in booting the DSL boot screen... but when DSL starts to boot it came an error:
"Kernel panic unable to mount root fs"

5. Also tried the dsl-3.1-syslinux.iso with the image and memdisk

root (hd0,0)
kernel /boot/isolinux/memdisk vga=0x0301
initrd /boot.img
booted to the DSL bootscreen, but then after starting
"can't find the fs"

I see only 2 possiblities:
point 3. above with the right commands which I don't know
or to point 4. with a greater image, but don't know how to create

Anybody can help me to succeed in booting this fine OS?

For me it works with something like (note that linux24 and minirt24.gz also have to be copied from DSL):

root (hd0,0)
kernel /boot/linux24 ramdisk_size=100000 init=/etc/init lang=us apm=power-off vga=791 initrd=minirt24.gz nomce noapic quiet BOOT_IMAGE=knoppix frugal
initrd /boot/minirt24.gz  

Please note that if you want to have multiple knoppix_dir (I do have DSL + KNOPPIX) there are extra problems - for instance DSL does not seem to be OK with knoppix_dir but KNOPPIX 4.02 is just fine and also the new KNOPPIX 5.10 with a special minirt.gz (about 2 MB, vs 1 MB the normal one)
knoppix_name and knoppix_dir works for me with DSL (using grub here)
