Reverting to OS9 on a NewWorld mac?

    I just got my new/used PowerBook Pismo. Being an unwise person, I immediately installed OS 10.0.4 on it. After a day or so, I want to go back to OS9. Unfortunately, I cannot get the beast to boot from any OS9 disks. No matter where I set the startup disk, the OX 10. eventually starts.

    I assume there is some picayune NVRAM setting that I need to change to make it look for "System Folder".

    Any ideas? I went through this same exercise on my WallStreet a few years ago, but I forget what I did to fix it :(

    As Yoda would likely say -- "Trainable you are not"

    I've never needed it because I started using Macs after X came out. I'm sure Help will have info on it.


    All current Mac models are incapable of booting directly into any Classic OS version, but they support OS 9.2.2 in OS X Classic Mode, although Apple has begun phasing out default installation of OS 9.2.2 for Classic Mode support.

    PowerBook 2000 (Pismo) will support OS 9.1 through OS 9.2.2,

    New Macs still come with Mac OS 9.2.2 bundled on the Software Restore CD, although on the newest machines it's not installed, and if you choose to install it, it only supports Classic Mode. Once you install, it's a good idea to drag a fresh copy of the OS 9 System Folder to backup media, which will allow you to restore it by simply dragging it back to your hard drive, instead of the tedium of running the software restore CD or DVD.

    On OS 9, your System was in /System Folder/ In OS X, /System holds your system, but other files such as system wide preferences are in /Library.

    Apple no longer makes any Macs that can boot directly into the Classic OS.

    Thanks for all the replies -- to clarify some things:
    1) This is a Pismo -- It can happily boot OS9, in fact that was installed when I got it (used)
    2) I did NOT receive the OEM CDs with the computer :(
    3) When I installed OS 10.0, I mistakenly told it to reformat the drive -- thus no classic available :(

    I have tried the things mentioned in the links. I'm trying to burn a bootable 9.1 CD, but my ancient burner is fighting me.

    I think I'm going to break down and get some RAM and install Tiger. Of course, this will only work if the retail Tiger DVD includes OS9!!.

    BTW -- I need OS 9 because I'm too poor/cheap to buy Office for OS X and I'm still not sure I prefer X either. I programmed Apples from the Apple II through the Lisa up to OS 9. Then I punched out as the skills I had acquired had become counter productive ;c

    Does anyone know if Tiger includes OS9? With the previous releases there was a way to buy a 9 CD for a pittance.

    Thanks again.

  5. It looks like there are two versions of the Pismo.Early and late prduction.I think the Powerbooks have their own CD's.You may need the OS 9.0.2 Powerbook CD or whichever version goes with that Powerbook.

    Once source I checked actually said the a Pismo could boot 8.6. I find this hard to believe.
