This is what i plan to do. Once i have finished modifying the package to also be usable on prep, chrp and chrp-rs6k, i will see if i can manage to diminish the kernel size to the needed size for a miboot floppy. This would maybe need to use a module initrd or something such, in which i have not much experience, though. Friendly, Sven Luther
