So I need to update my boot rom on my G4 AGP model Powermac. I am currently running 10.4.7. OS9 was not installed on it. So I moved the OS9 folder from my Powerbook G4 to my second hard drive and told the computer to start from that folder (starting up in OS9 to update the firmware). Now the computer starts to boot and then a little disc appears with a question mark and won't do anything else? First, I don't have OS9 discs and I really need to update the rom on the AGp model. How can I do this?
Got a tip for us?

You don't have an Mac OS X disks either? Just get the machine booted up and change your startup disk back to OS X, and go in and move things around again. Not sure why booting from OS 9 didn't work. If you don't have any startup disks (CD's or DVD's) then I don't really know what you should do.
Hold down the option key on boot up. You should be able to choose from all the OSs on your system, internal or external drives.
Wonder if that'll work... I thought you had to bless OS 9 so you could boot from it. I'm not sure copy and paste works.
bless should either make an attributes of the folder or make it known that the system has been blessed. That's how OS X installs is it copies everything then blesses it.funkychunkz said:

I think you need OS 9.1 for it to boot, so I would check that first. Next, your OS 9 installation may have machine specific information on it that the new machine does not handle, such as ROM stuff. If so, you probably need to get on ebay and buy a retail box version of OS 9 (OS 9.2 would be best). Once you have that, then install it to a clean external hard drive and then try to boot to it. I believe it will work.
