Firmware update on first iMac

I bought a brand new unused beautiful iMac 233mhz. Then I proceeded to update OS 9 to OS X Jaguar. But I did not update the firmware and that is where I got into trouble. After I reboot it goes to the white screen and has small type that says

"failed to boot
Apple iMac open firmware 3.0 f3"

I download what I thought was the firmware update but it says I need OS 9 to install it, but I did not put 9 back on the system so then I went in to install 9 off my cd and it won't continue the install because I don't have the proper Firmware on the Mac. What now? I can get it to reboot and work normally if I do the PRAM start holding down the option apple P and R at the start.

Anyway any help would be great!
 
The text message shows that you have version 3.0f3.
That's the most current firmware for the oldest iMac.
So, your issues are something else, but not firmware.
