Hi There, havent tried this myself but its worth a go


there is a procedure to override it: You need to change the amount of RAM in the machine (either add memory or remove existing memory in the expansion slot), and IMMEDIATELY, i.e. the first time booting after changing the RAM, reset the PRAM three times in a row. That means it needs to chime three times after the power-on chime. Once you've done this, you should no longer see the lock. It's Apple's "top secret" way to bypass an open firmware password.

to reset pram do the following

Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.

Why you think that a Mac computer has a bios?

If you forgot a password, load your Mac from the disk that you got when you bought your Mac. There is Reset Password.
Insert the disk, reset the computer and press C on start up.

A terrible option: Command+Option+P+R on start up.

Try this way:

There is an explanation about the RAM game. I'd try to disable it first.

Here is a more terrible proposal:
