Can an old iMac G3 drive running system 10.2.8 and system 9 be mounted in the secondary drive bay of a G4 800 Mhz running 10.4.11 and boot from the 10.2.8?

I've done this and the G4 800 Mhz boots up from system 9 on the old iMac G3 just fine, but when I boot up from its system 10.2.8, it runs for only 5 minutes or so and the grey screen comes down telling me to re-boot.  I've run Norton on the system 9 disk and system 10 disk utilities on the system 10 disk of the old iMac G3 and all is fine with it.  Is there some incompatibilities with running the old iMac G3 230 Mhz from the G4 800 Mhz that causes this to happen?  I can access all my old files on the iMac G3 when I boot up with extensions off (holding down the shift key when I boot up), but I would like to be able to use the USB functions when I boot it up.

    It sounds like you have a Power Mac G4 Quicksilver 2002, and according to the program Mactracker, it should be able to run on the OS 9 and the OS 10.2.8.

     

    I don't know which version of Norton (Utilities?) you ran on the old iMac drive, but I suspect that might be the problem.  This is from the iMac Tray Loading Service Source Manual:

     

    HFS Plus Formatted Drives

     

    The hard drive in the iMac is formatted with HFS Plus (also referred to as Mac OS Extended format). It is important to note that Norton Utilities version 3.5 is not compatible with HFS Plus (or Mac OS Extended format), and in fact, can destroy data on the hard drive.

     

    Norton Utilities version 3.5.3 or 3.5.2 will not attempt to repair a drive formatted with Mac OS Extended format and versions 3.5.1 and earlier cannot recognize that a hard drive is in Mac OS Extended format and can result in hard drive corruption and loss of all data on the drive.

     

    Note: When diagnosing hard drive problems, it is important to verify whether or not the customer may have used the wrong disk repair software for their drive before assuming that the problem is hardware related.

     

    If you experience problems with a hard drive that has been formatted with HFS+, Apple Computer recommends using Disk First Aid 8.2 (which is included on the system software CD that ships with the iMac). Disk First Aid 8.2 can be used to recover data that may have been deleted by Norton Utilities. (See the Symantec Web site at NO LONGER A VALID LINK-REMOVED FROM ARTICLE for more information on Norton Utilities and Mac OS Extended format.)

     

    Some other disk utility and disk locking programs are incompatible with Mac OS Extended format. Before you attempt to use a disk utility or disk locking program, make sure the version you have is compatible with Mac OS Extended format. Check the documentation that came with the program or contact the manufacturer or the vendor that supplied the program.

     

    Use the Get Info command in System 8.1 to determine how a hard drive has been formatted. Drives formatted with HFS will appear as “Mac OS Standard”, while drives formatted with HFS+ will appear as “Mac OS Extended.”

    I hope some of this helps.

     

    Good luck.

    10.2.8 should run on a your PowerMac G4 as it shipped with 10.0 or 10.1 (but potentially up to 10.2 which may or may not allow 10.2.8 to boot).

     

    Disk First Aid is on the OS9 installer disc, not a seperate one.

     

    Norton is bad news in OS9, too, not just OS X. I know this from bitter experience.

    We all know you can't take an original install OS disk from one model iMac and use it to upgrade another iMac of a different model because there are specific hardware issues and that's why you need to buy a full retail version of the OS.

     

    Could it be that since the OS 10.2.8 was originally installed on a different iMac model (G3), that it is having issue between hardware on the G4, and an extension(s) that were meant for the G3?

     

    Just a thought.

     

    Good luck.

    That's a valid thought, Joe.

    It may well depend on the source of the 10.2.8 installation. It's unlikely (but possible) that the G3 shipped with 10.2, so it may well be from a retail disc, or indeed from another grey disc, as G3s weren't as fussy about that as later models.

    Knowing the providence of the installation may provide some enlightenment.

    Another thought after re-reading your original post and replies.

     

    Since the hard drive with the OS 10.2.8 came from an iMac G3, and you're trying to run it on a Power Mac G4, could there be an extension conflict even if the OS 10.2.x came from a Retail install disk?  It definitely sounds like an extension conflict since it will startup in Safe Mode (extensions off).

     

    Maybe its the Graphics Card extensions.  All the iMac G3s had ATI cards and I think you have a NVIDIA GeForce graphics card.  That should be one extension conflict that might cause a problem.

     

    More food for thought.

     

    Good luck.

    I wouldn't count on this working, but...

     

    Copy all the NIVIDIA extensions and drivers from the OS 10.4.11 system and put them in the OS 10.2.8 extensions folder?  I don't know if you'd need to temporarily remove the ATI extensions or not.

     

    I don't know if you can download old drivers and extensions from the NIVIDIA website or not.

     

    Also, you said the OS 9 from the same hard drive as the OS 10.2.8 works just fine on the Power Mac.  Wouldn't the OS 9 have the same extension conflict as OS 10.2.8, or would OS 9 be less picky about the Graphics Card, or did OS 9 actually have the necessary NIVIDIA drivers for it?  Hmmm.

     

    Good luck.
