This worked very fine there last night, even in installing the Suse-PPC
7.3 without to have to do any changes in the distribution, alike new
kernel or so ;-)

1.- Copy the Suse-Boot contains folder to the root of a standard HFS
partition (inside a "System" named folder).
2.- Configure the Startup Folder Item from the MacOSX/MacOS9 prefs to
boot from this Suse-Boot "System" without having any CD in the
CDVDR-Combo-Drive.
3.- Let the Suse do its boot up to be hasked to put the Suse CD1 inside
the CDVDR-Combo-Drive. Let the rest of the installation run, just alike
installing on a x86 side box and... have fun...
