Amiga OS4 on old (PPC) Macs

[humppa]

The video is gone btw. was it removed by Amiga inc?  

Maybe Alex got scared after he got the 3 PMs from Raffaele (which he wrote in a "comatose state") and accordingly removed the video.  :lol:

[DBAlex]

Hehe, hello... Just woke up... Didn't get much sleep though... Heh.

@Raffaele:

Hehe, Thanks for the responses, I replied to your last one...! Nothing to worry about for now I think... :-)

@BooBoo1200:

Thanks! Nope it has to be the mini at either 1.33ghz with 64mb 9200 or the 1.5ghz with the 64mb 9200...! :-)

@AMIGAZ:

No, It wasn't removed by me or Amiga Inc... I've been asleep and in that time my whole hosting has gone down [Im awaiting an email - im guessing ive broke some terms of service... heh...] I'm guessing the hosting couldn't deal with all the traffic...

I don't think that the Ghz should make a difference, only the BIOS version.

Just upload it to some public webspace.

Yep but the "secret" speed bump that apple made are the only versions of the mini with the correct bios/firmware... [Until someone else confirms running it on a 1.25ghz or 1.42ghz model ] :-)

Currently no luck on my end - just black screen with option 4 and 5. I have a 1.25 mini w32MB Radeon. Any insight - I would be thankful.

[DBAlex]

@Debaser:

Tried option 1?

-------------------------------------------------------------

I forgot to tell everyone, also.  All USB devices are recognized (Keyboard + Mouse)... [With option 4 or 5] You obviously knew about the mouse as I got to the early boot screen but just confirming the keyboard works too...! [I can press the caps lock key etc] From looking at the files it also seems that Mass Storage devices can be used... [Boot from a USB key?]

Also, I was fiddling about looking at the files and found out you can also use the command boot cd:\\slb_v2_mm instead of the standard boot cd:\\slb ... The slb_v2_mm is more of a quiet boot, less output on the Open Firmware and it appears to be a little faster...! Also, im going to test plugging in some USB devices today to see if they are shown in Boot Options in the early boot screen.

Alex. :-D

@motorollin

Thanks dude, you finally found out how to make a torrent, hehe!

Yup, grab the video while you can, i've removed my link and the pictures temporarily.

[motorollin]

I will delete the torrent at the end of the day so please re-create new torrents or upload the file to web space or share the file on eMule.

you guys are great thanks for this.   :-o  Time to start looking for cheap mini macs


The future of the amiga is mini with the Mini Mig and now the Mini Mac  :-)  :-D  :-)

[spihunter]

Does anyone have a G4 Ibook to try this on.
They had almost the exact same specs as the Mini's

I sold mine last year! Damn! :oops:

[DBAlex]

OK, I just booted the CD again with Option 5 [CDROM MM_Full_Silent_USB] and it booted fine, intrestingly the USB mass storage device (1gb Sandisk Cruzer Micro) isn't recognized as a boot device, but if I don't go to the early boot menu and let the cd boot the flash drive flashes for a few seconds... Which possibly means its looking for files on it?  :-?

Anyway, I don't really want to say any more [Don't want to get into trouble] But i'm gonna try some more "things" in the next couple of days to see if I can push further into getting a more "successful" boot.  :-)

EDIT: also, I found its easy to boot from the USB key in the Open Firmware... You do the following:

setenv boota-device usb:

boot usb:\\

--------------------------------------------------------------------------------------------

I'm also thinking of combining the commands to boot from the CD and then the USB key E.g.:

setenv boota-device cd:
boot cd:\\slb_v2_mm usb:\\

Not completely sure that would work though... Would it just boot from the USB after its finished with the files on the CD?

Hope someone is a bit more clued up on how Open Firmware works and can help me out...  :-D

Fantastic work guys!  Thanks to you it looks like we may soon have hardware to run OS4 on!  Once you've got it sorted I will buy a Mac and a legitimate copy of OS4 now that it is on sale!

Question though....

You can only do this at the moment on Mac Minis with Machine ID: PowerMac10,2 (Thats the 1.33 and 1.5 GHz version).  That version of the Mini was available with 32MB or 64MB of Video Ram.  Now what is stopping OS4 booting on other Mac models?

Is it OpenFirmware version?  Is it the Machine ID?  Is it the processor speed?  I believe all these things can be spoofed with OpenFirmware commands.  e.g. you should be able to make it think you have 1.5GHz instead of 1.42GHz by typing:
dev /cpus/PowerPC,G4@0
d# 1500000000 encode-int " clock-frequency" property

Ideally I'd like to run OS4 on an old eMac or one of the iMacs with the swivel screen mounted on the dome.  I know its only a matter of time until this is possible, but I just want to understand what the limiting factor is at the moment.

Thanks and keep up the good work!

@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 (!)
