Installing OS-9 and OS-X to be dual bootable

Michael,

I'm pretty sure that paranoia means "They're out to get you", not "Out to get your stuff."



HAPPY HOLIDAYS!

Kappy

I wish I had developed this paranoia earlier in my mac experience and cultivated good backup habits. No going back, but if we learn from our experience as we go forward, all is not lost.

Hi everyone,

I read this all with interest and as I am a novice at this sort of stuff, a basic understanding is what I need!

I am thinking of getting a new iMac. I presently own 2 iMacDV's running 9.2.2. I have loads of software that runs fine on os9 and would like to continue using these to work with. Will osx allow me to use the older versions of Quark express and photoshop or must I partition also? Will Osx allow me to read older versions of Appleworks files? I suppose what I mean is if I have 2 partitions will the files of one system be readable by the other system.

Also it sounded like a huge amount of space needed for partitioning?

Allay my fears..........?

Dog lover,

Since you are a first poster you probably are not too familiar with forum etiquette and terms of use. If you click on the Help & Terms of User ("?") in the forum sidebar you can read up on terms of use. Etiquette asks that you post your problem as a separate topic and not add to an already existing topic - this is called threadjacking and is frowned upon.

We also ask that you search the forum, FAQs, and User Tips for answers to your question before posting a topic. In many cases you will find your question has already been discussed and solutions already provided. This is certainly the case for your topic.

Thank you for understanding and good luck.

sorry, thanks for the advice!

Kappy:

Thanks for your gentle redirect to DogLover. I remember jpl's very gentle approach when I first posted in the PB G3 Forum and he has been my mentor every since, as you have also become for me. I think one of the special things about Apple Discussions is that although most first-time posters do it with fear and trepidation (not to mention their frustration and anxiety over their problem), the gentleness with which they are received makes it easier for them to come back not only to receive help, but, as in my case, to be of help.

I just wanted you to know I appreciate what you do.

Kappy,
When creating a partitioned drive for dual booting you state that BOTH OS partitions be HFS+. Yet, one purpose of HFS+ Journaled allows OSX to track file bits/parts eliminating defraging, as I understand it.

It has been a while since I fired off my B&W G3, but it does have both 10.3x and 9 in seperate partitions. I'm sure that the 10.3x partition is Journaled and am not sure what scheme is used in the 9 partition. However, both OSs work as advertised.

I've used the Boot Manager and the System Pref to switch between either system at different times, as I recall. I could be mistaken, but I believe I installed OSX first as HSF+ Journaled (DU) and later 9 as HFS+ (DS).

When doing maintence I only needed to defrag the 9 partition.

Further, I'd particularily recomend this dual OS partition to users of Pagemaker, which seems to write its files willy-nilly and cause major problems under heavy extended use.

Correct me, if am wrong.
Thanks,
Chris

You can only journal an OS X system. Journaling does not work in OS 9 (that is when booted directly into OS 9.) However, you should format both partitions as Mac OS Extended. With Panther and Tiger journaling is turned on by default when you format a drive. There is no need to defrag the OS X volume unless you have lots of files in excess of 20 MBs. However, the OS 9 volume may require occasional defragging if it's under heavy use.

Kappy,
I realize that about journaling in 0SX and that does not work in 9.

"There is no need to defrag the OS X volume unless you have lots of files in excess of 20 MBs"

20MBs! You must mean 20GBs.

"However, you should format both partitions as Mac OS Extended."

That seems to make no sense to me, since Mac OS Extended (Journaled) is a good feature of OSX. Why do you recommend not enabling this feature on the OSX partition?

Chris

Please re-read. As I said journaling is the default for OS X, so when you choose Mac OS Extended for an OS X volume it will have journaling turned on by default.

See the following about defragging:

http://docs.info.apple.com/article.html?artnum=25668. And, yes, I do mean 20 MBs, not 20 GBs. I'm referring to individual files that are 20 MBs or larger.

I have found this discussion topic extremely useful. Thank you.

I have followed your suggestion of Dec 6th, 7th and Jan 16th

I am still Unable to install a bootable OS9 system on to a 2nd partition, I am however able to install OS 10.4.4 on to the 1st partition.

Here’s what I got:

2.5 G5 quad with two internal drives 1st is a 500GB, SATA HD in bay (a) as the primary drive with OS 10.4.4 installed, and the 2nd is a 250GB SATA HD in BAY b partitioned in two parts, both MAC OS Extended (journaled).

I have tried to create two partitions one Extended (journaled) and the other just extended for the OS9 still unable to install OS9 as a separate bootable system

Reboot with “C” down does not recognize the old OS9 installer disk, and the OS 10.4 disk wants to just install OS9 as a non bootable disk.

How do I install a Bootable OS9 system on to a separate partition.

Much appreciated

You do know that your G5 cannot boot OS 9? The only way to install it is to install the special version that's included with your computer's Software Restore discs.

Thanks Kappy for your prompt reply:

I did not know that I could not Install a separate bootable OS9 on to my G5, hmmmmm that’s a bummer, Well!! Can I however install a bootable OS9 on to an external firewire drive, and if so how.

No, because you cannot boot a G5 into OS 9 regardless of where you install OS 9. You can only use Classic by installing the special OS 9 that comes with your Software Restore discs. See the following:
