May be sheer superstitious ju-ju on my part - but as I ran into this scenario again yesterday, I’m wondering if there might be something to it after all?
Attempted to option-boot Tiger on a Mac Mini with both 9.2.2 and Tiger 10.4.6 installed on two separate partitions. Regardless of choosing the Tiger partition, the Mini would then boot into OS 9.2.2 without fail, as if Tiger “was not there”.
Now I’ve come to adopt the following as a habit when setting up dual-boot G4s - to use Drive Setup 2.1 to initialize and partition HDs and SSDs first. Because using Drive Setup 2.1 allows formatting beyond any 128 GB drive size limitations for drives larger than 128 GB, whereas Drive Setup 1.9.2 does not.
And also why I prefer the
MacTron Bootable Rescue CD & Disk Repair (
http://macos9lives.com/smforum/index.php/topic,1657.0.html) over the
Mac OS 9.2.2 Universal Install (
http://macos9lives.com/smforum/index.php/topic,2109.0.html) … as Drive Setup 2.1 is on MacTron’s and Drive Setup 1.9.2 is on the Universal.) There may however be a new viable alternative to both, here in the not so distant future.
And I believe that DS 2.1 is now available on the Mac Mini V.9 installer as an option, whereas earlier versions of the Mac Mini 9.2.2 installer only had Drive Setup 1.9.2.
Now back on track… normally after dual partitioning the HD/SSD and installing OS 9.2.2 on the first partition (whether on a G4 Mac Mini or other G4 / OR even a G3 Blue and White) I usually installed Tiger from an Apple retail installation disc. Therein perhaps lies the rub.
For years I attempted to install Tiger on a G3 Blue & White… AND after those many attempted installs, the B&W would not boot from the new Tiger installation / partition.
Then finally, I tried the Tiger installation by
FIRST opening Tiger’s Disk Utility, from the booted Tiger install disc BEFORE the actual Tiger install. AND then erasing the Tiger-targeted partition as “Mac OS Extended (Journaled)” before then returning to the actual Tiger installation. After so many previously failed attempts - THIS pre-step method actually allowed the B&W to boot from the new Tiger-installed partition.
You’ll find Tiger’s Disk Utility under “Utilities” in top menu bar after selecting “Use English (etc.) As The Main Language” after booting from the Tiger install disc.

So yesterday I reinstalled Tiger on that Mini using this same above procedure and it worked. Easily booting back and forth between OS 9.2.2 and Tiger afterwards.
Now, had I originally used Drive Setup 1.9.2 on the Mini in question? I don’t remember.
And is there something about the Tiger installer that it expects to be installed on a non-partitioned HD alongside a previously existing OS 9? Again, I don’t know. Could you simply “Enable Journaling” on a Tiger installed partition from a booted Tiger Install disc, AFTER the first installation without the pre-step? Again, I don’t know.
AND “Enable Journaling” on a single partitioned HD/SSD with OS 9.2.2 & Tiger in the above manner - might have negative consequences? No, I’m not going to test that.
*IIRC mopar300m just followed the Erase & Format “Mac OS Extended (Journaled)” Tiger pre-install procedure with his B&W & his DA with no problems (after also deleting the Multiprocessing folder).
I know this all reads like gobbledegook but it’s merely a rough “run-down”. Hopefully others can make sense of it and provide a better step-by-step guide - IF it is valid?
OR dispel the whole affair as mere bunk.
