Mac mini Os4

[os4macg4]

Hey, the webpage is updated.
Still with newbies information, but anyway, a little bit deeper.

"And it freezes.
TBContinued with more information." :lol:

[os4macg4]

Hey, at least I'm trying, since everyone is AFRAID to post detailed instructions...
If some good soul wants to give me further details about the installation process, plz send it to os4macg4@gmail.com

I'll delete the e-mail and the identity will be kept secret.

I don't see you trying. This is something we'd all like to see happen. If you cannot contribute in a positive manner, say nothing. I admire the guy for working on it. People laughed at the OSX86 project but it is mostly stable now.

No one's knocking the attempt, but the methods are dubious. The proper route:

1. Buy a copy of Amiga OS 4.
2. Learn the ins and outs of U-Boot.
3. Learn the ins and outs of Open Firmware.
4. Reverse engineer the U-Boot boot loader.
5. Write an Open Firmware boot loader.
6. Write device drivers for the target platform(s).

In general, the boot loader is going to do things like:

a. Initialize the hardware (MMU and whatever else OS4 requires).
b. Implement file system support (FFS, SFS, etc.). This could be done in Forth in Open Firmware or as part of the boot loader, which can be Forth, ELF, or anything else supported by the target platform.
c. Search for an appropriate boot device. The Moana boot loader uses an environment variable for this.
d. Read the layout file, which should include all necessary drivers.
e. Prompt for choices, if there's more than one.
e. Load the kernel per the layout file and user choice.

Open Firmware itself is open source and Forth is a well-established, well-documented, and proven language, so there shouldn't be any question about how to get generic information in those areas. The open source boot loaders for Linux and other operating systems ported to PowerPC Macs would be a good place to start for the Mac-specific stuff.

Writing device drivers is tricky, as the SDKs for some driver types, e.g. Picasso96 card and chip drivers, are not publicly available.

6. Write device drivers for the target platform(s).

it seems to me that will be the major obstacle..
look at linux and its troubles

its even more difficult at a.org since there are 99% whiners.... erm! windows users i mean and 1% amiga programers...

[hbarcellos]

OK, but as far as I know, It's already possible to run OS4 in a Mac Mini, with Moana boot loader, isn't it?

@A1260

And u spend a 100% of ur time on this forum, {bleep}ing, tolling and putting people down.

Give it a rest ffs

Andrea Vallinotto made it quite clear that the Moana ISO has been stolen and that distributing it equals piracy.

I'm really baffled that this thread is still open, not to mention the links to illegal download sites that can be found in here.

[Ferry]

Ditto. Not only this, but the fact that this thread contains links to pages pointing to pirated software and the links have been there for nearly a month, without they being removed by admins or mods... :-?

Saluditos,

Ferrán.

Are there any news regarding this topic?

As I (like lots of others) just own an A4000 which will not work forever and also does not have the necessary power and memory capability to run AOS4 satisfying I'm looking for good alternatives!

And the Mac Mini PPC is the best ATM for me!

Unfortunately I'm not firm at all with AOS insides as well as UBoot and so on concerns (my Amiga-Programming is limited to coding the normal API for Games or similar)!

I still hope that AOS4 will work on Mac Mini sooner than later since I do not expect the lawsuit to be finished/solved this year (well attorneys and judges also want to live as we now) or maybe not even next year. And furthermore it is very unclear what will happen afterwards!

Bye

any progress on this?

We need a new thread, this one is too long!

I agree, let's start a thread titled "Pirates of Hyperion's last chance to make a profit".  :lol:

It is quite a dilemma for those of us who want to do the right thing and would gladly pay for AOS4 if we had something we could run it on, knowing that someone out there right now is probably successfully running AOS4 on their MacMini, or other PPC Mac.  There does not appear to be any end in site for the lawsuit(s) and even if there were it is unclear if either party that may win will ever release the code to allow AOS4 to run on PPC Macs, and for many reasons.  Some selfish and narrow minded and other reasons that are legal in nature and very complicated.

I think that the only way we will have AOS4 running on OUR PPC Macs, will be to have a group of very talented programmers reverse engineer the code that was leaked illegally, and create our own patch code that will allow us to run the only currently available version of AOS4, the version for Classic Amigas.

Unfortunately, the above solution is highly unlikely to happen in the foreseeable future either.

So, for me anyway, being unable to contribute to such a task, I will just sit back with my popcorn and wait for the lawsuit(s) to conclude in 2 or 3 years and then wait another 3 or 4 years for either winning party to do anything of significance, by which time I probably won't give a damn.  :madashell:

I agree, I would happily buy a copy of OS4 if it ran on a PPC Mac Mini.  I don't understand this, if all rights to OS4 were indeed transfered to Hyperion during Amiga Incs dieing days then why can't they sell a version that runs on PPC Macs?

Also what has Hyperion got to worry about, if they lose the suit all they have to do is create a company, maybe call it LMOS and transfer all their assets to it icluding the Hyperion name and let the original company float away as a company named Hyperino...
