Well I had previously Mac OS 9.0.4 and my friend had the CD installation CD of Mac OS 9.2 so I booted up the computer and then installed Mac OS 9.2 but now when I boot up the Mac it just give me that error Error Type 102 and tells me to hold the shift key to turn off the extensions. I have done that But I have had no luck.

iMac G3 CRT, Mac OS 9.0.x

    Was...

    1. The CD a "home made" CD using the OS 9.2 update files downloaded from Apple.

    2. A universal/retail install CD?

    3. A CD from another model Mac? (This won't work.)

     Cheers, Tom

    Well the CD that my friend had was compatible with my iMac G3 but do you think I had to install the update firmware Mac OS 9.1 before I had it upgraded to Mac Os 9.2?

    You need to install incremental updates to get to OS 9.2. See http://docs.info.apple.com/article.html?artnum=75288

    Okay today I got a Mac OS 9.0.4 disk for my iMac G3 Slot Loading but I booted up and it worked and I installed it. Now again I have the same problem it tells me this

    Sorry, a system error occurred.

    error type 102
    to temporarily turn off extensions, restart and hold down the shift key.

    Apple KBase Article #9806 translates Error 102 as -

        102    dsOldSystem    System is too old for this ROM

    Since your iMac slot loader originally came with OS 8.6, it's hard to see how any OS 9 version would be 'too old'.

    However, that error message may be a result of an incompatible OS 9 version being installed.

    Since your imac originally came with OS 8.6, you should use only retail OS 9 Install CDs (white label, gold 9). Those with gray labels and a model name on the label are model-specific, and may not have files compatible with your machine. You can't trust the ability of the CD to boot the Mac - the OS installer does not use files from the System Folder on the CD.

    Suggest you get hold of a retail OS 9 install CD. Specifically, if you want to end up at OS 9.2.1 or OS 9.2.2, get a retail OS 9.2.1 Install CD.

    Alright I have fixed my problem Don Archibald
    I just couldn't find the Restore function on the Mac OS 9.2.2 CD. Well I was looking around the apple web site and I found out how to do the Restore and now I have it all upgraded and ready to install Panther or Tiger. By the way what would you recomemnd better?

    Hi, Frank8723 -

    What is the processor (machine) speed of your iMac?

    How much RAM is in it?

    How large is the hard drive, and how much free space is on it?

    The Processor is PowerPC G3 Machine Speed 400MHz

    RAM = 192 MB

    Not sure but the Hard Drive is around 10 to 20 gigs

    Hi, Frank8723 -

    Your iMac (Slot Loading) model is rated by Apple as suitable for either Panther or Tiger.

    However, it is at the low end of acceptable models for Tiger; and your machine speed is probably a bit low to get the best out of Tiger.

    More to the point, Tiger requires 256MB RAM as a bare-bones minimum; a more realistic minimum is twice that, 512MB. Since your machine has but 192MB RAM right now, Tiger will not install on it at all. You can increase the RAM in the machine - it can hold up to 1.0GB of RAM.

    Panther requires a minimum of 128MB RAM to install; again, twice that is a more realistic minimum.

    Recommendation - Panther (OSX 10.3) is probably a better choice than Tiger (OSX 10.4) for your machine.

    In either case, plan on having about 8GB of free space on the drive before installing OSX (in addition to install space, OSX runs best when it has about 5GB or more free space left over).

    Important - be sure you have updated the firmware in your machine before even trying to boot it to OSX, including OSX on an install CD. You can obtain any needed firmware update from either of these Apple KBase articles -
    Article #58174 - iMac: When to Install Available Updaters
    Article #86117 - Firmware Updates

    Be sure that you acquire a retail package for OSX, and not a model-specific one.
