Hi

I want to install OS X 10.4, 10,5 and MorphOS on the same PowerBook (5.8)

Have any of you succeed doing that??

Double install is quite easy, but I've never thought about triple (two OSX) one.

It's been a while since I did a dual install on a Mac. From memory MorphOS has to be installed on an internal drive. OSX does not. So unless you have a large internal drive one or both of your OSX's can be on an external drive.

Have fun.

If you find some general Mac dual-boot instructions for several OSX installations, MorphOS can always be added afterwards if you just leave some space for it... or MorphOS first and maybe OSX's later depending how the dual boot goes with them :) Anyway, I think the key question here is if you can do dualboot with OSX's easily. MorphOS will always work with its own boot partition etc.

I've multi-booted OSX on PPC Macs in the past without issue. That should not be an issue. Besides holding down the Option Key during boot you can select or while running OSX go into the System Preferences and select Startup Disk.

Over time, I have stopped using OSX entirely, its not updated for PPCs and don't I run MacOS on my X64 platforms.
So my Macs only have MorphOS installed on them (although I'll occasionally play around with Linux).

Personally, since we now have cores and memory to spare, instead of switching between OSX and MorphOS, I'd like to see a Linux distro that could be run on the unused excess capacities of some of our higher end systems (concurrently with MorphOS).

Updating Ambient to handle the display duties for two OS' probably would not be as difficult as some of the other proposed upgrades.
And if SMP was ever enabled in MorphOS, it would still be nice to be able to support more than one environment.
And Linux could provide a quick path to full OpenGL compatibility.

I'm not proposing a replacement of Quark here, just a possible expansion idea (low hanging fruit again, I know).

I have 2 osx and morphos in ibook
First was 10.4, after 10.5 and the remaining space is Morphos

Just one single core, until the X5000/40 gets supported.

That would be nice. Pity that Apple irreversibly disabled the PPC970's hypervisor in their G5 machines via firmware.

...within the Linux environment ;-)

Sounds like you would enjoy something like A.L.I.C.E., but built for MorphOS, instead of AmigaOS3.x. I am not sure how the A.L.I.C.E. system works with multiple CPUs, or CPU cores, but I assume that any Linux software run on the A.L.I.C.E. system, would still be capable of using all available CPUs/Cores, while the AmigaOS3.x running would be limited to a single CPU/Core.

That would be provided with A.L.I.C.E., but only for the Linux programs running transparently from the A.L.I.C.E. desktop.

An A.L.I.C.E. like solution for MorphOS, would require replacement of Quark, as it would be running on top of a minimal Linux system, if I understand how A.L.I.C.E. works correctly.

I have been meaning to install an A.L.I.C.E. system on one of my computers for a while now, so I could check it out more closely, but haven't taken the time to do it yet. It seems to me to be a very desirable choice for an all-in-one Amiga-Like system, that can also run most Linux and Windows (through WINE) software applications and games, transparently, just as if such software were running natively on AmigaOS3.x.

I've done it, and also installed linux, for a total of four os's on one powerbook :)

It wasn't super hard. I can't remember the details but as long as you use OSX to partition the disk initially and you ensure you create the required boot partition for morphos, it isn't too bad.

Or we can convince them to port to a Quad G5.
And you have to wonder why the hypervisor there was disabled.
After all, Apple loves control schemes and proprietary technologies.

Yeah, that IS the ugly part.

At least I didn't suggest concurrent BSD (although in a weird way that would be one step closer to OSX).

MorphOS does run on a Quad G5, the question is - will this version ever be public?

My IBM-related suspicion is stated in the comment I linked to :-)
