Triplebooting Pegasos II

[Piru]

So, one suddenly realizes that one of the HDDs actually has unpartitioned and unused area on it. What to do? Boring solution would have been to partition the area for some more por^H^H^Hcontent.

Instead this is what I did:

I finally figured out how to set up Mac OS X for Pegasos. I also installed Debian/GNU Linux unstable with the latest kernel. When booting the system presents a nice menu to choose the OS to launch. By default, if no action is taken, it will boot into MorphOS.





Mac OS X install is using Molk 0.7, the bootmenu is implemented with BootCreator.

Well, nothing new there really, but at least I can now impress some guests with the multiboot capability. :-)

How well does mac os X perform on a pegasos under emulation then?

There is no 3D graphics acceleration, so graphics operations are the slowest part. Graphically intensive operations such as video playback are painful (more like slideshow, due to missing hardware acceleration).

The good news is that otherwise it runs pretty close to the native speed of the hardware (it doesn't do any CPU emulation after all). Thus it's slightly slower than 1GHz G4 Mac. My experience of the emulation is just 2 evenings so far, though.

Does OS-X make heavy use of the GPU for the attractive filtering effects and animation (resizing/minimising etc.)?

Yes it does, and all these are done with CPU with MOL.

How does this perform?

All these effects are naturally slower than on a real Mac.

However, I must say I was quite surprised how well these effects perform still, even without GPU acceleration. For example the zoom effect on the panel is very snappy, no obvious slowdown is visible there. Minimizing windows to panel is slower (most of the time it's fullscreen effect), but it still isn't slow, it just drops frames, so it's a bit jumpy. It doesn't bother me, personally.

You can also disable these eyecandy effects if they bother you.

There is no difference.

Mac OS X is available for purchase though, that's the difference I can see.

But the boot.img doesn't contain the 68k emulator which would be needed for AOS3.9, right?

static 68k emulation is inside the boot image, the JIT is not.
