Amiga OS4 on old (PPC) Macs

[DBAlex]

@Ohforf:

Hehe, Thanks, You did something I was too scared to do... everyone go watch now...  :-D [Although its not that amazing ]

We also need to thank AmigaMac... I hope he turns up or at least gets un-banned from EAB (!)

[CoolamigaN]

Whether he gets unbanned  or not, he shouldn't return there. Enough hostillity on EAB, specially on the thread AmigaMAC user created.

Agreed! I was quite shocked by some of the responses in that thread.

As long as OS4 is not really running, it might still be a Hoax,
or incomplete Work.
It takes a 1337 H4xx0r and a lot of Time to get this one running.

[maffoo]

This is making me start to regret selling my Mac Mini a few months back  :-(

With any luck, once it's up and running on a Mac Mini it will only be a matter of time before it's running on other PPC Macs.

Yes, I followed your conversation with some people over there and I was very tempted to register just defend you and anybody else that was being attacked out of the blue. Without any real reason, just because they wanted to run OS4...

Unfortunately for you the OS4 fans, that dont seem to understand this not being a hoax is definitely not a very good thing. Instead you are mostly cheering. You all is too stupid to see the big picture. Reminds me of Lemmings.

The probability of new lawsuits materializing between old and new players has greatly increased.

DBAlex has now actually helped Amiga Inc, I think we have not seen any court document on this matter because it has not been proved working, now that Amiga Inc have proof you can expect a document stating HOW Hyperion has NOT been able to protect their IP and moving their Amiga Inc's operating system to another hardware that is not licenced, aka not AmigaOne. Amiga Inc probably have a copy of the leaked iso also.  

Now Hyperion will go down and lose in court and your beloved AOS4.0 will be forever trapped.

Good luck in killing of AOS!!

So what will Bill do with the OS4 code if he wins? Lock it up in a safe and call it a day?

OK, I have the 4.2GHz machine with 32MB of VRAM and just get the black screen. I must mention that even 6 months ago (I read this somewhere on the net that long ago), the Moana files where proved on only mini machines with a certain amount vram. From the get go it was said that vram was the whole problem. The whole 32MB of VRAM from Apple was a joke anyway! What can you run with that small amount of vram? I got Lego Star Wars II for xmas and can't even run it 'cause it requires 64MB vram!  :madashell:  What that has to do with the OS4 loader is probably just a matter of vram addressing (needs to start in a different location than the 64MB vram model.

Using option 4 on the loader cd, I did however, manage to get the the 32MB VRAM to initialize to some sort of video mode (white background with blue character font) so something is failing to continue right after video init on the 32MB VRAM model. HINT!

Alex, could you post a thread listing all the different startup commands that you have received from various folks? I will try each of them here on my 32MB VRAM machine.  :-)

Also, someone may want to try to modify vram addressing in the actual loader routines....   :crazy:

@gizmo350

Hehe, Sounds about right, although as someone posted earlier I think you can spoof these things so that OS4 can boot on every Mac... I PM'ed the guy but he hasn't responded. (beakster2)

The only commands I have received are the standard ones that everyone has:

setenv boota-device cd:
boot cd:\\slb

I also found out though that:
setenv boota-device cd:
boot cd:\\slb_v2_mm

Also works... and the slb_v2_mm is more of a quiter boot with less Open Firmware output, I don't think it will magically boot your mac if its not the 64mb model though... You can give it a go though.

Im trying to contact beakster2 about spoofing the openfirmware for the boot rom version and the vram [if thats even possible] so far he still hasn't responded though.

Alex.  :-D

Apple really made a G4 1.5ghz MINI?  I cannot find any info on this machine.
I only found the 1.25, and the 1.42ghz versions.mmm..
I did find info on the 1.5ghz intel Mac Mini..

Please someone clarify, which model is required, and why doesn't the 1.25,1.42 Mac Mini work?  I have a G4 1.67 PowerBook 17"..why wont it work on any of these machines..or even an older G4 @500mhz..
Please someone explain.

Thanks
Rich

interesting.... Maybe the 1.5ghz G4 64MB Radeon is the "special" Mini it was made for?

There was never officially a 1.5GHz G4 Mini - some people who ordered the 1.42GHz model got the 1.5GHz model instead (with 64MB of video RAM.) See here for details.

Apple did make this machine, as I own it!

Apple quietly updated the Mini's to an overclocked spec, The 1.25ghz Mini was overclocked to 1.33ghz and the 1.42 boosted to 1.5ghz... They didn't publicize this "secret" speed bump and it was luck if you got one or not [Luckily I did]

I think [I'm talking with beakster2 over PM's now] that the way to boot it on those machines is to spoof the Open Firmware into thinking that your machine is either a 1.33ghz with a 64mb Radeon 9200 or a 1.5ghz with a 64mb Radeon 9200... Im asking beakster2 now if its possible to spoof the vram amount, he says that it IS possible to spoof the CPU spped though (read his post on the previous page)

Alex.

Any link to images or videos? All links in the thread ar dead.

OS4 couldn't be in a worse position than it already is (no hardware available for it to run on other than ancient hardware and the occasional second-hand A1.) This could encourage more development for OS4, increasing the market and encouraging AInc to actually release new hardware instead of just promising it. People may then buy the new hardware rather than rely on out-of-production PPC Macs.
