Before any of installation on my computer, my os was 9.1.
I have installed 9.2.1. But then I decided to install back 9.1.
I inserted the 9.1 disk but I couldn't install back 9.1
There is an error. "Bus error. To temporarily turn off extensions, restart and hold down shift key"
How can find the solution for my case...
Thanks...

Why do you want to downgrade? MacOS 9.2 is a hardware compatibility upgrade to MacOS 9.1. The features of the two operating systems are the same. You will gain nothing by going back to MacOS 9.1. Again, why do you want to do it?
 
Have you tried upgrading 9.2.1 to 9.2.2? There might be some fixes there that would make your experience a bit more pleasing.

I would figure that 9.2.2 would have some maintenance updates that fixed issues possibly found in 9.1.
 
9.2 is mainly for Classic. For native use, 9.1 is usually better. 9.2 introduced a lot of application and peripheral incompatibilities.

Have you tried turning off extensions like it says? And are you booting from the install CD, or your hard disk? Any more info would be helpful.
 
Hello,
After your recomendations, I decided to upgrade to 9.2.2. I will purchase the software....
my ibook has 64 mb of memory. Does it require extra memory?
 
os 9.2.2 is free, just connect to the internet and run system updater. as far as ram, if vm is on, 64mb will do, but will be slow. try to get at least 128, but 256 is best with vm off. not knowing which ibook you have, can't tell you for sure if you can even get 256 or more. i ran 136 ram on a 7100 with 9.2.2 with little problems.
