"To check your firmware version, press Command then Env 1; the display will read "NO COMMANDS ON PAGE," but that's not really true - it's a "secret" page where the diagnostic software resides. Scroll to the right until you see the SOFTWARE INFORMATION page, and press Enter. The display will show the current RAM VERSION (the disk O.S. version you booted up with). Press Enter again to see the ROM VERSION (the firmware version)."
