I think OS4 CAN be run on MAC MINI (USABLE)

[jj]

Its not 100% from what ive been reading though.

Thought quite a few things ddidnt actually work on it, network and sound for instance.

Is there eveidence of people running apps and games and uae stable on these, andd system ffriendly  68k apps etc etc

It DOES work, Hans: there's a LOT of people there out using it. THE ONLY PROBLEM comes from an outdated ROM VERSION in our Mac Minis.
For me, it's "as soon as Amiga OS 4 runs on my mini, OSX can go hell".
And I repeat: IT'S usable, IT RUNS, and WE have to find a way to start using it in every Mac Mini with a PowerPC processor.

show us videos and pictures NOW!!

I can tell by all the activity on all Amiga forums that the Mac Mini version is working great and tons of people are using it.  



If this were the case you'd have actual users posting in this thread showing proof of this with steps required/system requirements, other than some youtube video.  I'll be getting  a G4 mini sometime this week so I can try it out on that machine but after that it gets deleted since I'm not a OS4 user.

Just wait for that RADEON-Rom flashing and you'll see...
There's people here who has it working. I f I become one of them, I'll post pics & videos

Last I checked the only flashing tools available were for the OEM gfxcards.

So how exactly would anyone flash their Mac Mini?

Its more like beta testing something ACube never had a chance to do.

Rom Revision - System Profile /Graphics?

Can you install Display 4.5 and see if it updates the Rom Revision.

It looks more like the correct Rom Revision is 113-xxxxx-133 can some confirm?

For those having problems accessing the Mac mini Open Firmware, try using an Apple keyboard.

I found that using an MS and a Logitech keyboard both resulted in no open firmware, yet other commands such as reset PRAM worked fine. Switching to an old Apple G3 keyboard worked fine.

Can get as far as a purple screen with dodgy colours - as others have described. To me this looks more like an incorrect screen resolution or refresh rather than a graphics card problem, but I am no expert.

Mac mini G4 1.42GHz, 1GB RAM
ROM 4.8.9f1
ATI Radeon 9200 32MB, ROM 113-xxxxx-116

Good luck, this is an interesting development!

[kickstart]

I dont seepeople with mac minis runs os4 on it, some user some pages back in this post tells that runs on a 1,42 with 32mb gfx memory... if this is true, why people dont explain it?

Now somt post back people speak about flash radeon version just for test, this is pure hype

By the way this is my radeon version 113-xxxxx-116

Linux has PROC, it makes possible quite many things like dumping firmwares of your graphics cards and such. Maybe it's possible to write on it too, I think it can be possible.

So maybe using Linux could solve the problem of AmigaOS4 not running, ironic eh? :-D

[BooBoo1200]

ATI flahes might not Flash your mini but other macs with OEM Cards and points to the fact there may be enough difference in the Rom Revison to make a difference As there have been been problems and mac has updated the Rom Revison for better compatibility and more features.

I dont know if it can be flashed but linux distros have come up agaist this problem and over come it.

Mac Mini radeon has no ROM or firmware visible in the PCI space, so linux can't even read anything from it, yet alone write.

@BooBoo1200

Funny that it works just fine with other OSes such as *BSD, MorphOS, etc.

Can you point any workarounds enabled in linux for example?

[BooBoo1200]

The amount of web pages ive been through!!!!
But I read a post and they updated the Driver to suit the Rom Revison in this case that is not possible.

[BooBoo1200]

I think the previous link I provided answears your question

No, it does not.

If the "problem" is like described in that message, then the problem is in the "custom non-osX-OS" radeon driver, not the firmware.

Also, it is a well known fact that Apple never released any flash updates for the PPC Mac Minis.

 Apple has a strange relationship in wich they pay to unlock features of the underclocked Radeon in the MacMini - Moana may not have patches for the lower probably more locked Radeon Rom Revision . OSX patches these holes

In this case update the driver or update the Rom Revision probably no need for both - Better drivers would be better but this is an unofficial project.
