i just downloaded DSL 4.4.1 and managed to multi boot it..
heres how..
1) i extracted everything from dsl-4.4.1.iso to a folder named DSL
2) i copied everything within folder DSL\BOOT\ISOLINUX to folder DSL
3) i copied everything within folder DSL\KNOPPIX to folder DSL
4) i deleted folder DSL\BOOT
5) i deleted DSL\LOST+FOUND
so the folder contents of DSL are...
Quote
boot.cat
boot.msg
f2
f3
german.kbd
isolinux.bin
isolinux.cfg
KNOPPIX
linux24
logo.16
minirt24.gz
finally here's the isolinux command i use to call DSL from cdshell.ini

if $lastKey == key[b]; then isolinux /SETUP/DSL/linux24 ramdisk_size=100000 init=/etc/init lang=us apm=power-off vga=791 xmodule=fbdev initrd=/SETUP/DSL/minirt24.gz nomce noapic quiet knoppix_dir=/SETUP/DSL/ BOOT_IMAGE=knoppix
its all one line... and i made some changes...
1) i kept folder DSL in a folder called SETUP (doesn't matter where you put it. just remember to call perfectly from the cdshell.ini menu)
2) i use the above command to redirect to the following files LINUX24 / MINIRT24.GZ / KNOPPIX.
finally, i set my file system to ISO 9660 and ROCK RIDGE...
