Which iMac is it?

"A serial number is a unique, identifying number or group of numbers and letters assigned to an individual piece of hardware or software. It's used for various things depending on the product / brand but what is your Mac's serial number for and more importantly... what is it hiding and what can it do for you ?"

Sep 5, 2013 11:22 AM in response to becks87by Baby Boomer (USofA),G3 iMacs need firmware updates in order to go from OS 9.x to OS 10.x.
First thing you need to do is to read http://manuals.info.apple.com/en_US/ReadBeforeYouInstall10.2.pdf<---- DIRECT DOWNLOAD prior to installing anything relating to OS X on a G3 iMac.

Sep 6, 2013 6:20 AM in response to becks87by Allan Jones,Functionally, 512MB RAM is about the minimum to let 10.3 work properly. Apple officially says less but the 512MB is based on my experience and many others here.

Sep 6, 2013 2:06 PM in response to becks87by MichelPM,Actually, that model can take 1 Gb of RAM.
With that much RAM installed, you can, probably, run OS X 10.3 Panther comfortably.

Sep 6, 2013 2:14 PM in response to MichelPMby MichelPM,If you have OS 9.04 installed, you would need to first find, purchase and install OS 9.1 or OS 9.2.
Then, you need to install this firmware update next before even thinking of installing any version of OS X.

Sep 6, 2013 3:56 PM in response to MichelPMby rccharles,The 9.x point release are free. Download them from this apple site:
http://support.apple.com/kb/HT1387
There is a small chance the machine my have the firmware already installed. Here is how to check.
You need to figure out the level of your firmware before installing 10.2 or greater. ( The PC name for firmware is BIOS. ) Installing 10.2 with a down level firmware will most likely make your iMac unusable and difficult to fix.
What is Open Firmware?
The firmware on a PPC is called Open Firmware. Open Firmware software receives control when you poweron your machine. It does some hardware testing and some hardware configuration then passes control to your version of Mac OS. It reside on a PROM ( program read only memory ) chip on the logic board.
Figuring out what level of Open Firmware you have?
1) Mac OS 9.x or 8.x, you need to use the Apple System Profiler.
Apple -> Apple System Profiler
2) Open Firmware, boot into Open Firmware.
Power on your iMac while holding down command+option+o+f
The first output line contains the firmware level. Mine reads:
Apple PowerMac4,1 4.1.9f1 BootRom built on 09/14/01 at 13.18.04
Copyright 1994-2001 Apple Computer Inc.
On my machine, I have 4.1.9f1.
What firmware do you need?
http://support.apple.com/kb/HT1395
You can download the firmware from this page:
http://support.apple.com/kb/DL1283
filename: N-iMac_FWUpdate_4.1.9.smi.bin
avoid expanding the file on the download computer.
For a slot loading iMac, this article indicates that you need to be running 9.1 or later version of Mac OS Classic.
http://support.apple.com/kb/DL1283
"The iMac Firmware Update 4.1.9 will only run on iMac computers with slot-loading CD or DVD drives running Mac OS 9.1 or later from a local drive. If you are using Mac OS X you must boot from a local Mac OS 9.1 or later writeable partition (not a CD, or network disk) prior to following the update instructions."
You can download the Mac OS 9 updates from the Apple site.

I believe so. You will be able to run less applications at the same time without excessive thrashing of the disk.
