G4 firmware updates

[mrdave79]

I've just got my hands on three G4 AGP Power Macs and in my rush to upgrade them to OSX I didn't upgrade the firmware. I now find that I can't use 512mb Ram as it only works with the current firmware update. But I no longer have OS9 to boot from so how do I update it? Or where can I find OS9?

I await your pearls of wisdom.

You got to boot up from another hd with OS 9 installed, then run
firmware update. Maybe possible even from an external drive.

If it helps, could even be done with a FW iPod.
