There is a brilliant guide I followed for setting up double and tripple boot systems.   Where did i get if from ?


I never bothered with boot menus, not on the Pegasos, not on the Mini. But I knew there was some effort(s) done on this on the Peg, and a quick google pointed to this one:
http://aminet.net/package/util/boot/bootmenu

Have no idea of what use it could be though...

EDIT: I'm *not* an expert on these matters (which probably shows), but we who used Pegasos (at least in the early days) had to use OF/SF a bit, and here is something in the line of what I would do if I were you: Here is some info on how OF finds Apple's boot image (read under "default boot device" (BTW, notice that "HD" is an alias (like Amiga's "assign") and not the actual path, read more about actual path on "Open Firmware Capabilities")). I guess this one should be useful for one of the entries in the boot menu, yes? Now find out the MorphOS one. If the concept of OF device-trees, paths, partitions etc is confusing, maybe this (chapters 4, 5) will be of help? I would try to cd and ls my way all the way to the boot image (why not write down the path on some paper as well?). Then, when you have found the exact path through the device-tree to the boot image, and can make a single ls *from the root* to list the place, then you should have what you need for the MorphOS entry in the boot menu. I'd be very careful not to do any "setenv" commands (in step 5 of the boot menu instructions) before actually making sure that *all* your settings/paths in the forth script works as they should (step 4).

Again, haven't actually looked at the script. But if it isn't working, it should be possible to modify...?

Please report back! :)
