Xandros Level 1 Level 1
When I installed tiger on my iMac I chose the option to install OS 9 drivers on the HDD so I am able to boot into OS 9, all I need is a bootable OS 9 folder! The OS 9 folder currently installed was created by the classic environment installation that came with my Tiger install dvds, however I notice in the readme for the software it says one cannot boot from these folders.

I presume it is because it lacks a few extensions that would otherwise be necessary for the system to boot without problems. I just wondered if anyone in the know had a definitive list of what files I would need to make it bootable. I do have OS 9.0.4 install discs and all the os 9 updates, but rather than use that to install a folder and go through the bother of updating it (and some of the updates install software I don't want - it is somewhat annoying to install 9.0.4 and have a large degree of customization over what is actually installed, only for the os 9.1 update or whatever to ignore any previous selections and install all the software I didn't want anyway).

What I wanted to do is use tomeviewer to open the os 9.2 and 9.2.2 updates to locate whatever files it is I need for the system to be bootable then stick them in the "non-bootable" classic install. I'm guessing, mostly all I need is the graphics card extensions.

    Hi Xandros;

    Before going off trying to get it to boot, you really should determine if in fact your Mac can boot in OS 9. If you can provide us with more details about your hardware, we might be able to tell you if this is even possible or not.

    Yea, it can. Its an old iMac G3. The OS 9.0.4 install disc I mentioned came with it.

    I have OS 9.2.2 & Tiger 10.4.11 on separate partitions on my G4's hard drive. I can boot to OS 9 or 10.4, or if I'm booted to 10.4 I can still run the OS 9 applications via classic. You might consider a partition set up.

     Cheers, Tom

    I'd rather just have both system folders on the same partition, it would mean I could avoid formating the HDD and reinstalling Tiger as well as OS 9.

    I don't think there is a list of those files, and it would vary from computer to computer. I remember when in fact a bare bones bootable system was just having a System suitcase alone - you didn't even have to have Finder if it didn't matter to you. This was as recently as OS8-something when I made a bootable rescue floppy with System suitcase and Disk First Aid renamed as Finder.

    Running a few updates shouldn't take all that long.

    Have you even tried booting from the currently installed Classic?

    Classic Mac OS
    First off, Tiger (10.4) installer does not install a bootable 9. In fact it does not even install 9 installer, unless it is a system specific Tiger installer that came with another Mac. Tiger was release April 25, 2005.
    System specific Mac OS X 10.2 installers were the last to be able to install a bootable Mac OS 9, and at that only for those Macs, and only if you installed the Mac OS 9 drivers as indicated below:


    You can use Disk Utility of another Mac to install those drivers, and then use your 9.0.4 retail installer which came with your iMac to install 9.

    http://docs.info.apple.com/article.html?artnum=75288 lists all the updates you might need.

    Funny, it didn't even cross my mind to just try and boot from the folder anyway. I took the document about the Installer as gospel - it says it can't be booted.

    I just went into startup disk and booted to it. Didn't chuck out any errors or anything...

    Well, I'm glad you found a solution even though it may leave people puzzled as to why it works. Perhaps something to do with it being such an old computer that it can make do with fewer resources and ones still available with just a Classic version install...?
  • Xandros Level 1 Level 1
    I'm just as stumped as to why it works. I thought at the very least it would have needed the extensions for the rage video card but apparently not.
