Powerbook G4 unable to boot in OF

[galgot]

Hi,
I've been experimenting OS9 on a PowerBook5,1 G4 17" 1Ghz model A1013, using the tricks from OS9Lives site, here :
http://macos9lives.com/smforum/index.php/topic,3912.0.html
All works fine, except for the few things that are broken with OS9 on this model of course.

Now the disk is a 60Gb, so I thought I could have Tiger on a 30Gb partition.
Plugged the Book on a iMacG5 running Tiger, then using Disk Utility formatted the disk in two partition, first 30Gb HFS+ Journaled for Tiger, and second 30Gb HFS+ for OS9. All in Apple Part Table and with OS9 drivers.

Then installed again OS9 on the HFS+ part.
Again boots fine.

Then cloned a Tiger install on the HFS+ Journaled part.
Boots all fine on it.

Now I thought I could select the boot partition by holding the Alt key at startup. No…
It boots direct to Tiger.
Also it doesn't want to boot in OF and it doesn't want to zap PRAM…
Startup preferences doesn't see the HFS+ with OS9 installed as a bootable volume.
So I have no way to boot from that OS9, even though I know it's bootable, as it was before I cloned the Tiger install on the other part…

Any idea how to select the boot partition, or what causes the PB not wanting to boot in OF ?

Boot keys not working is possibly coming from a power management issue. In any case if there's nothing major you can set your OF variable auto-boot? to false to boot directly into OF. Just

sudo nvram auto-boot?=false

in a terminal and next reboot should end up there. reset-nvram + set-defaults from OF will revert the variable to true.

If you want to set your boot volume to Mac OS 9 (with an unsupported machine), I like to use bless. Given the system folder is (already) blessed, something like

 sudo bless --mount /volumes/(your os 9 volume name) --setBoot

should set the good boot partition, but

 sudo bless --folder9 /full/path/to/your/macos9/systemfolder --use9 --setBoot

will set the boot folder as well. Since I switch between 9 and X a lot I have a command-line script for that. There's always the bless man page.

Hope it helps.

How do you switch back to OSX from OS9 in this scenario where Alt/Option doesn't show the boot list and you can't access OFW?

Thank You ! Will try that and report

Edit:


Bless command works perfect. Thanks again.

Good to hear! 1Ghz PB looks like a pretty nice machine for Mac OS 9.
