Yes, absolutely, but more thanks to other factors than RAM amount.

It is at least for the Macs.

Triple booting with Linux is yet another thing, but there're also threads on this.

On PPC Mac, use APM (Apple Partition Map) for all OS drives.

As I told you back in February, there's GRUB/GRUB2, and there's also old Yaboot. But none of this is really necessary as your Mac has a graphical boot menu built in.

iMac:
- Install MacOSX from installation DVD, leave 2/3 space unused for other systems. You have to partition disk manually. And MacOS hardisk tool is.. ehm.. far from ideal. Simplest method is to made three equal partitions and on the first install MacOS X. After that, delete two unused partitions.
- Install Fienix.
Also leave part of disk unused.
- Install MorphOS
- you can select system by graphical bootmenu - press Alt ( Opt on Mac keyboard ) when booting.

Sam460Ex:
- at first, select graphics card compatible with all three systems ( like HD 6670, X1950 ). I.e card compatilble with MorphOS, fulfilling also this. Install PCI SATA SiI 3114 or 3512 controller.
- install AmigaOS from DVD. Your system volume format you must be SFS, not SFS2 ! Set boot priority to 5. Leave enough space for other systems. For AmigaOS you need buy additional drivers like ( Enhancer ).
- install MorphOS.
- for linux check forum.hyperion-entertainment.com and amigans.net. It works, but it is not so automatical, there are some manual work.
- MorphOS and AmigaOS you can select by bootmenu ( created automacically ), linux should be started from U-Boot command line.
- generally, for start I recommend install only one system separatelly. Check it Test it. Play with it. Delete and install second. Than third... Only after that decide what you want.

From my point of view this is easiest way. There are many other ways how to do it. More optimal ways, but more complex to setup.
Anyway, if you are beginner with powerpc, I strictly recommend not to try install all systems on computers.

If you want to play and test, I recommend only this setup:
iMac: Fienix and MorphOS
Sam460ex with RX550 gfx card: AmigaOS.
Forgot for MacOSX. Use it, only if you have special reason.

I am not tested Fienix on iMAC, but it should work and this is far easiest linux.
And if you wait long enough ( til January probably ) I will publish some detailed article about three systems on Sam460.

Thanks Sailor, thats it!
I know of Fienix as part of making most recent PPC Linux for AmigaOnes and have latest version on stick.

I just already have installed MacOS X, can I resize partition from installed MacOS X and create two more?

There are games like RTCW, Doom3 I like on my iMac plus some productivity software, but since it doesnt have decent browser and office, maybe you are right :D
