First of all, make sure to have img or smi files instead of dmg
files. All the original downloads are available as .smi or .img
files. I haven't found any System 9 update files in dmg format
on Apple website.
Your Mac is capable of using MacOS 9.2.2, but I have been unable
to find my localized version (Dutch) on Apple's web site.
Fortunately, I downloaded it earlier.
If you want to update from 9.0.4 to 9.2.2, you have to use all
the update files. First you update to 9.1, then 9.2.1, and
finally, if you can find it, to 9.2.2.
You may have to update firmware as well, during the process. So,
make sure that you have the latest firmware available. Probably,
this should be version 4.1.9. (You also may have to install the
iMac CD update 2.0, but it is possible that this is installed
automatically with MacOS 9.2.x.)
