Mac OS 9 booting on: Mac mini G4 (Detailed Posts)

[Volga163]

Good afternoon :-)
I'm happy to try Mac OS 9 on my Mac Mini 2005.
I'm going to make a video with quick comparison of games running in Classic Environment and native Mac OS 9.2, also with demonstration of a way of dualbooting both OS X 10.4 and OS 9.2 (slightly fixed alexfree's tutorial). Are you interested in it?

Best regards, Vladislav.
P.S. English is not my native language, feel free to ask if you didn't understand something.

Done

tasty music, but someone give this guy a copy of RTCW.

n-as-mac-mini:~ na$ nvram auto-boot?=false
nvram: Error (-1) setting variable - 'auto-boot?'

What am I doing wrong? Thanks!

[RossDarker]

Try with sudo

[theG4fantastic]

OK. I blessed the Mac OS 9 partition.

I got the nvram to dual boot.

The OS 9 disk appears as a selection after multi-boot. It starts for a brief second, then I get the disk with ?.

Any ideas?

[IIO]

isnt that because the mini ROM already contains an OF patch which includes a reset?

I just got my mini working well with normal tasks but is anyone having or have had trouble with the mini crashing on pro tools or a daw dealing loading an audio file on an ssd ? Every time the system crashes when I import a wav file or run through playing it , i feel pretty defeated about hitting these forums with so much problems each time , I apologize on my idiocy

[IIO]

not sure sbout 5, but PT 4 likes a volume limit of <176gb ... there´s lots of info somewhere in the protools sections.

[Aksis]

I totally get that my man , I should be in the clear considering it’s a 50gb SSD , it doesn’t like the disc allocation from my tracks made on the PowerBook (considering it has a hard drive) so I’m wondering what the issue is, but other than a crash caused by creating a new file that was already there (cause I didn’t save the session after importing a track which is dumb)  I’m pretty good to go

[IIO]

as long as you dont try to stick 3 farm cards in the mini, all will be good.

[Aksis]

Never mind , I imported freshly made files into pt5 and the Mac crashed a quarter way calculating the overview and processing the audio , when I try to import audio it crashes way too often and this is horrid for the workflow, I can’t chalk it to anything , it did a similar problem when I first got the machine , booted it and tried to make an alias for classilla , this is just simply unbearable

[IIO]

eww, if it also happens when creating an alias then it is time to do a RAM check i guess.

This maybe stupid question but has anyone tried to boot Pismo into OS 8.6 or use Mac OS X Server 1.2v3 ?

[RossDarker]

Once tried 1.2v3 on a g4 mini but was never able to get past the splash booting screen with the spinning CD (beach ball). But if you mean pismo PowerBook then not sure.

No ideas; I'm stuck at the same place.  I'm using version 9 of the unsupported Mini image currently.  Tried wiping the entire drive, same issue.  Tried manually booting the Mac OS ROM from Open Firmware, same issue.  I've got the thing booting into 10.6, but OS 9.2.2 is stumping me.

Well, I realized I made a newbie mistake.  I booted into 10.6, fired up a terminal, and typed in
sudo bless -folder9 /Volumes/macos9/System\ Folder -use9 -bootBlockFile /usr/share/misc/bootblockdata

Then rebooted and bam!  Boot into OS 9

So now I've got a G4 Mini dual booting Mac OS 9.2.2 and Mac OS X 10.6 PPC.  Still need to work out a few kinks on the 10.6 side, as some bits don't work as expected; probably need to replace with 10.5 components.  But OS 9 works great!  Thanks to everyone who spent so long putting that together!

And it feels really weird having a Mac that can run OSes released 10 years apart from the PPC era.  Usually I have to pull that off via emulation.

Well, I realized I made a newbie mistake.

it would not be a mistake if you booted into 10.6, it would be an absolute innovation.
