how to set firmware password and FileVault

[mnya]

Hi! using OS x snow leopard here.
How do I set my firmware password?
I thought I insert Snow Leopard install CD and go to Utilities? But I don't see "Firmware Password" section in there... Am I supposed to use another disk? I lost all the other ones..

Also, if I want to set up FileVault for security, do I need my Master Password? What happens if I forgot it?

If you want to use FileVault, I'd recommend upgrading to Lion or Mountain Lion. They have FileVault 2 which does full disk encryption and it performs better than FileVault in Snow Leopard.

Don't forget your password. For FileVault2 you can actually store the encryption key with Apple. Note the encryption key is different (and much longer) from the password(passphrase) that you use to normally access the FileVault 2 protected system.
