XPostFacto

The sweet spot for OS X on the Kanga is 10.2.6, as the video kext works at thousands - you can go to 10.2.8 but save the kext, and I believe the same for 10.3.
Also keep in mind OS X needs to be installed on the first partition of the HD, which has to be below 8GB in size. To keep it clean, partition the HD in two - the first 8GB for OS X, and the latter for OS 9.1 - files etc won't get messed up then.

Hoping to do the same with my Kanga soon :)

My problem is that I don't have OS9.1 install disks, so wiping the hard drive and partitioning is not a viable option. My plan was to just install OSX10.2 of some sort right on top of OS9.1. My understanding is that this is doable and I can just switch between System Folders using the startup control panel. One of my Kangas appears to have an 8.6 installation on it as well, and it looks like I can switch between it and 9.1. Haven't tried it because I'm not sure if the 8.6 install is any good, but in theory I could. The current drive has plenty of space for OSX with space left over, so once I get the system fully operational (it needs a new keyboard and PRAM battery) I'm going to try to track down some OSX CDs.
I can't say it will work for you with a laptop, but when I installed the new 80 GB hard drive in my Power Mac G3 (rev. B) , all I did was format and partition the NEW drive then I copied over my entire OS 9.2.2 System Folder to it and it was bootable. I have had no issues with at so far. I also have made system 7 floppy boot disks the same way, except using just the minimum required files (Finder, System, Enabler etc).
That would probably work given the way that OS9 works. That being said, installing a new hard drive in a Kanga is a complete pain from what I've read in the service manual.

 
I was thinking More along the lines of using SCSI (it does have a HDI 30 port or something, right?) to copy everything to another drive as a backup, then formatting and partitioning the drive in the kanga, and finally copying everything back to the drive (plus it defragments your files!)

 
My understanding is that this is doable and I can just switch between System Folders using the startup control panel.
Correct. In OS 9, the Startup Disk control panel was tweaked to facilitate easy switching between OS X and OS 9.
 
Keep in mind, however that its only OS 9.1, 9.2.1 and 9.2.2 that have the newer version of the Startup Disk control panel that allows you to switch between system folders. OS 9.0.0 and 9.0.4 still have the older version that only allows you to choose between different volumes.

 
The current drive has plenty of space for OSX with space left over
If your current drive is bigger than 8GB, you can't install OS X on it. A Mac with "old world" ROMs like the Kanga can't boot OS X from anywhere beyond the first 8GB of the drive. OS 9 can be anywhere within the first 128 GB of a drive. If your drive is bigger than 8GB, you need to repartition it with a 7.9 GB first partition, which will hold the OS X system. OS 9 can be installed in that first partition or in a second partition which covers the rest of the drive. If your drive is smaller than 8 GB, then you have no problem, and can install OS X on top of OS 9. It may take a couple of shots with XPostFacto to get all the options right. There were a few where I had to guess and picked the wrong one, but eventually I got it right, and OS X worked very nicely until there was a major crash and everything had to be reinstalled again from scratch.

If you don't have install disks for OS 9, then risky behavior like XPostFacto may not be a good idea.

It's a 5GB drive...and I also just found 9.0.4 and 9.2.2 install discs. The 9.2.2 disc doesn't work in the Kanga though, it says it will only work in an iMac.

 
As best as I understand it OS 9.2.x is officially supported only on Apple G3 or later Macs (Beige G3 or later).

Do not attempt to install OS 9.2.x on any unsupported Mac unless you are willing to risk the chance the system won't boot, possible drive problems, etc. Also as i understand it the OpenGL 1.2.2 installed by OS 9.2.1 is not compatible with 3Dfx graphics cards if that matters to you.

When I used XPostFacto on my 8500/Sonnet G3 PCI card i only had 9.1 installed because when i did that i was completely stupid ( not that I am any wiser now ) as to how to use XPost or what OS 9 should already be installed. Plus i was not aware of this forum to help me thru the installation of Tiger on a unsupported Mac. I only knew that I had to have an 2nd internal hard drive because the factory drive was only 4 or so GB. I also learned the hard way that i could only use the internal CD driver for installation because using an external CD drive results in a failed installation. Since I had to use the internal 8500 CD drive the installation disks had to be CD's ( unless that has changed ). I was lucky to get an Apple tech guy to provide me with a copy of Tiger on CD at no charge. Well that's my sad story about installing OS X on my unsupported Mac.

have OS9 Helper. http://www.os9forever.com/er, specifically: http://www.os9forever.com/os9helper.html
Just for my own understanding are you indicating that i should have installed 9.2.2 before installing OS X with XPostF ?

Also not sure i really understand what the advantage would be of having 9.2.2 on the original/primary hard drive when in most cases the primary objective of installing OS X via XPostF is to run OS X from mac hardware Apple does not support running OS X.

Personally I do log back in to the hard drive that has OS 9.1 ( using XPostF startup control application ) and then log into OS 8.6 ( on that same drive ) simply because most if not all my midi/audio programmes freeze in OS 9 which stands to reason since those programmes were written prior to OS 9 architecture.

I also learned that it is a good idea to partition the second internal drive and install OS X to both of those partitions.

 
... you.. just do not get it do you?

Not saying you have to install OS 9. Just saying that it can be done.

Where did you hear that? And why should it be done?

Take it easy Mr MacJunky:

when you say

... you.. just do not get it do you?
when i read your post i was not challenging what you said it was only that at the time of reading your post it was to me rather unclear . Furthermore, i am not a certified apple tech guy which is why i joined this forum not to challenge what was written by anyone only to learn and if we don't ask we never learn. If i make a mistake in replies or participating in the thread (s ) then there is a polite manner of correcting that for the benefit of all . Otherwise what's the point of having this forum in allowing the exchange of ideas and thoughts. As i noted when i first read about using XPost to trick my 8500 to run OS X there were no forums such as this one to guide me thru the process. As a result i had a horrible experience and what i call disastrous results whereby i had to turn to a local apple tech shop to get my 8500 working again.
So my friend if i offended you please accept my apology

 
Take it easy Mr MacJunky:
I was. At no point in time was I angered.
Furthermore, i am not a certified apple tech guy
Nor am I. Being an Apple tech is not gonna help you get OS X running on old hardware anyway since they are not trained to do this sort of thing. Generally it is just "Oh, it does not work anymore? hmmmmmm... what does Master Steve say? Archive and install! Oh.. that did not work? uhh, Master Steve says to toss the computer in the trash and get a new one!! YAY!! :D "/me rolls eyes

and if we don't ask we never learn.
You just made many passionate and dedicated librarians cry. I hope you are happy with yourself. :p hahaha. I amuse myself with what I say sometimes. :)
So my friend if i offended you please accept my apology
No offence has been taken and I do not intend to do the same but you are not my friend. There are only a few people who I have met online that I would consider to be actual friends. Everybody else are just people I have encountered at varying levels of knowingness.(yes I made up a word)
Ok, time to get back on topic now, enough thread jacking with emo crap for this week. :p

I have never heard that before this thread. Did the person who's words you read mention what purpose it serves?

wow

 
Yeah, XPostFacto is just one of those products that sometimes takes a bit of mind twisting to figure out. Personally, my first use of it sorta was through BootX of all things to cram Linux on my old macs. Then the XPostFacto that used BootX to get things going.. It's been a while for sure, but once figured out it's very powerful and handy to have around.

My last use of it was to get OSX 10.4 on a Beige G3 Desktop with the non universal 1Gig G4 Sonnet in it... I REALLY REALLY miss that machine now. But cash was needed and out the door to a friend in Mexico it went.

So basically, yes, format your drive if you only have one drive to put the OSX partition in the first 7.9 (8 gig) of the drive max, and then say a 400 meg OS 9 partition anywhere up to the 128 Gig mark if you have one that big.

IF you need to go to a different hd for OS 9, just configure XPostFacto to use the right helper partion/drive.

The most confusing part to teach the guy that bought my machine was how to properly update the OS when XPostFacto was installed. Syncing up is very necessary I've found.

Good luck,

 
5GB will be tight, but you're OK to install 10.2 along side OS 9 on a single partition. Good to have an OS 9 install disk or complete backup in case something goes wrong and you have to reformat and start from scratch.
