Amiga OS4 on old (PPC) Macs

[BooBoo1200]

With all that was going on I forgot to say Well done DBAlex:-)

Would I be correct in saying any MacMini with a G4 at 1.5Ghz would also have the upgraed Radeon 9200 at 64MB not 32MB

We also need to thank AmigaMac... I hope he turns up ...................................

Thanks AmigaMac

Just to clarify the Minis with upgraded CPU  1.33, or 1.5 will always have 64 Mb-vram as well? and never come with 32mb-vram?

If it is the version that runs on a Classic Amiga w/PPC that is currently for sale I will place my order today in hopes that the bootloader will continue to be worked on until it is able to work with many more models of PPC Macs. I have a 1ghz PowerBook that needs repairs that I would love to run OS4 on.

:-) Same Here

Im eager to find out what happens but if we already have the kernal maybe Os4 classic will work?

@gizmo350

Hi probably wont work but have you tried maybe editing the ISO and renameing devs\usb\hcd\ohci.usbhcd or devs\usb\hcd\ohci.usbhcd_safe to devs\usb\hcd\ohci.usbhcd_deb who knows :-)

@DBAlex or anyone else Hows it going have you managed to progress any further?

Info elsewhere seem to sugest that full Os4 on Mac is possible I like to post a Quote originally posted on EAB the poster said the Info came an anonymous good soul at the bottom it sugests partitioning the HD with workbench but still booting from CD?
 

So, here goes... if this doesn't work, nothing will:

For starters, stop the booting sequence and enter the OF prompt by pressing Ctrl-Alt-O-F *right* after the USB keyboard gets detected.

Now, type exactly that:
boot cd:\\slb

Make sure you use the 'MM_Full_silent_USB' configuration, number 5 probably.

You can update those old kickmodules, but *DON'T DO ANYTHING* to the following files (including kernel files):
battclock.resource-via.kmod
macminiide.device.kmod
dbdma.library
nvram_OF.resource.kmod

If you want to do an iso from those files, you can easly use mkisoft by typing:
mkisofs -v -o -R -D -iso-level 3 -h -part -mac-name
-hfs-bless /l

What's more, you can partition the HDD with workbench on the mini, but it needs booting from the CD anyways.

PS: Got from an anonymous good soul...

Maybe the kickstart is looking for a FFS formated HD but whether this would work with Classic?

[BooBoo1200]

Yep thats a good idea - I wonder if its possible to make a dedicated FFS partion under Mac OS/E-UAE like with with WinUae then copy over the Os4 files -Maybe Im going in totaly the wrong direction here? I may have to wait until someone in the know gets a Mac? I dont know if I can wait that long :-P
