Firmware PasswordI have a G4 I just picked up but I can’t even get it to boot from the boot cd. It comes up with a firmware password, anybody know a way around this? All I get on the screen is the floder with the ? and the smile, then it comes to a screen with a lock. Thanks About slapelu |

Power the unit off, remove power, change the memory configuration, then power on.
I change the amount of physical memory and rebooted, even tried tp take the battery out and let it sit of 1/2 hr. But it still asks for a password..any other ideas would be helpful.
Thanks
You need to change the RAM config and then reset PRAM on the first boot following that change.
I have change memory taken out the battery rebooted with both cmd-opt-n-v and cmd-opt-pr. still nothing.
I can boot into cmd-opt-f-r but anything I try to do asks for a password..
Help…..
Thanks
I’ve got the same problem with a G4 I got from a major university after they upgraded to G5’s. I’ve looked everywhere, and have not found an answer. Everybody keeps telling me to cmd-opt-whatever. If they had read a little, they would know you can’t do any cmd-opt combination, or boot off any external drive without a firmare password. I’ve seen a post where a person with the same problem just had the apple store fix it. Not sure of the cost, but I doubt it was cheap.
If the apple store can do it, than anyone should be able to do it. Apple is more like IBM with this proprietary crap. I can’t believe that I can’t find any documentation about this anywhere. Isn’t there some apple techie willing to give up some info on how to do this?
I’m betting that there is special hardware/software to reprogram the firmware chip. And I don’t think the firmware chip is like a bios chip on a pc where you can just take it out and replace it, or buy a cheap eprom burner, burn a rom image onto it, and pop it back in. I can’t see any removeable chip on the G4 motherboard, but then again, I have not taken the processor board off, or looked on the backside of the motherboard.
Gak.

Adam that works fine if your g4 has the default password in place. However if someone changed the default password you cand cmd/option nv or cmd/option P/R till the cows come home after adding or removing memory and removing and replacing the battery and its not going to do anything to reset that firmware password. Get it? Comprende dude?
Um, that was Apple’s official technote that I linked to. That’s how you reset it. You think Apple’s wrong about how to reset their own system?
