I recall from a lonnnng time ago (10.0.x days) that firmware updates had to be done using OS 9. However, I have an iMac G3 500 and I haven't had to update any firmware since then (as far as I can recall). Surely we can't still be required to use OS 9 to update firmware, can we? Hope someone knows better than me. Have you tried searching Apple's support forums for "imac" and "firmware" and perhaps "g3"?

It's true check out this Apple support page for details. Look at the bottom and it will tell you to install the following updates under OS9.

For maximum compatibility and stability, make sure you have the latest firmware updates for your iMac.

iMac Firmware Update 1.2
iMac Firmware Update 2.4i
Mac Firmware Update 4.1.9
iMac/Cube DVD-ROM Update
iMac CD Update 2.0
