Protect your Mac using an Open Firmware banner

You have to be sure to remove the system memory chip as well as the user memory chip. This requires you opening up your case, so be weary.

I must have had a unique iMac then, as I opened the case, removed both sticks of memory, disconnected every wire and connector, removed the battery, left it open overnight, and it still wouldn't forget the OF password.

The RAM config must change: i.e.: the total amount of RAM must change between cold restarts AND hold cmnd-opt-p-r for 3+ chimes.

What you are suppose to do is take out all the memory, and then boot the machine without any memory. Shutdown by holding the power key for 5 seconds, re-insert memory and it should work.
