Open Firmware Tricks

von

Ein paar praktische Open Firmware Tipps gefunden bei Mac Geekery:

  • Reduce the amount of memory your computer uses, or “remove” a RAM stick in software by editing what Open Firmware sees on the logic board.
  • Reset Open Firmware to resolve general hardware issues.  Enter Open Firmware with CMD-OPT-O-F after a restart and then type in reset-nvram then set-defaults and, finally, reset-all to restart the computer.
  • Useless trivia: A side effect of Open Firmware’s stack-based command structure is that it doubles as an RPN calculator.  Try the following: 2 2 + .
  • You can access Open Firmware over telnet if you really want to.
