My Mac won’t use open firmware. HELP!

I tried doing into open firmware but it didn’t work. I tried command+option+O+F but it didn’t work.

Computer:MacBook A1181. Newer Apple recovery not supported. Just some info.

Steps:

1: Press and hold Command+Option+O+F.

2: There will be white text on the screen.

To boot the Mac you apparently you have to type this: mac-boot
To reset your Non-Volatile ram/(nvram) type: reset-nvram
