View Full Version : powerbook g4 boot from dvd issue

Jan 3, 2010, 08:46 PM
i have a powerbook g4 that is currently running osx leopard 10.5.4 i think.

It has a password that i apparently forgot and the password hint i set is completely useless.

i have tried booting from my retail leopard osx disc by pressing c when the powerbook turns on and that has not worked. it fails to boot up for some
reason. also used a tiger dvd to see if that would work. failed as well.

i've also tried entering single user mode, but that fails.

i also think i tried pressing the option button when it starts and that failed.

at one point i got a screen with an arrow and a blank text field and lock icon.

what exactly is that?

any tips on troubleshooting this further? This has been very frustrating.

Sounds like you have a firmware password set.


I don't know of an easy way to reset it, though. That's kinda the point.
