See lock Icon when Option button is pressed at system start up

Having troubles trying to reload an iBook G4 12" (1.33 GHz 512MB, 40 GB HDD & DVD/CDRW).

When option button is pressed during the startup, a blue screen comes up with a lock icon, a progress bar, and a right arrow button.

Also during normal startup, instead of the normal apple logo, its a flashing square icon with a globe of the earth, then it goes to the regular folder icon and mac logo (the one that indicates there is no operating system) and pressing C at startup doesn't work either.

Anyone ever had this problem? Anyone know how to fix it?

I just want to say, "Thanks for looking out for the rest of us, when we have a question". I was able to fix the problem (firmware password) and it turns out the solution was rj713's comment and the link he provided in regards to the mac mini. (http://www.macworld.com/article/145418/2...) All I did was add memory to the machine, then turned it on, during apple sound I held down command-option-p-r to reset the PRAM and voila, no more problem. Again thanks to everyone.

You have locked the firmware (Master) Password. This can be turned off in System preferences but you will need to remember the password. You may also have activated it by turning on File Vault.

Use your original system installation disk and start up holding the "C" key down. If this fails, start it up in Target mode via firewire cable with another Mac and use Disk Utility and wipe the hard drive. Then start over with the system disk and install a new system. Please stay away from the master password.

The master password can be a real nasty bug. Before you pull the drive try changing the RAM configuration. You get one shot with each change. Try resetting the PRAM on the first change. Then change it back and try the Target.

mayer is correct--here is a link on the procedure. This one is a Mac Mini but the procedure is the same. +

I was afraid of that. Holding down C key doesn't work, neither does starting it up in target mode via firewire. I may have to pull hdd physically and connect to another mac to wipe drive. By the way, I didn't do this, a customer did this to their machine. I have to fix it.

I used this answer from Dan Frakes at Macworld. This worked for me on an Apple G4 iBook 1.07GHz model. I had just changed out the hard drive on this laptop that I bought off of eBay from a school district. Dan's solution: There’s a back door to firmware passwords: You can bypass the password by changing the amount of physical RAM inside the computer and then resetting PRAM during the first boot immediately after the RAM change. In other words, if you change the amount of RAM in a Mac, it will start up normally one time to give you a chance to reset the PRAM; if you don’t reset the PRAM during that boot, firmware-password protection will be restored the next time you boot.

so can you do anything if the firmware is re enabled at reboot?

What do you mean? If the drive is good and has a working OS on it after clearing the hardware password that should solve things (unless the drive was encrypted).

Heres the trick you'll need to clear the hardware password: The unbootable Mac mini this works across most of the older Mac's.

I used the solution that Mayer stated in the Chosen Solution above and it worked for my situation, however, rj713 provided the link to a more detailed "how to" that I followed and used to fix my problem.
