A possible fix for misbehaving FireWire devices

Regarding your original firewire problem on your G5, Apples standard troubleshooting mechanism for firewire issues are to reset your nvram. I have zillions of firewire problems on my mini, and this always fixes them (steps below).

Regarding your firewire hub - be careful - adding a firewire hub to my mini actually *caused* lots of new problems - drives conflicitng with each other, devices failint to be recognized, etc.

Steps to reset nvram (from here):

  • Power Down
  • Hold down Cmd-Opt-O-F
  • Power On
  • at Open Firmware prompt, type:
    • reset-nvram
    • reset-all (this just reboots)

A possible fix for misbehaving FireWire devices

Actually there's a line missing in your instructions ("set-defaults"):

-----
Start the computer while holding down the Option-Apple-O-F keys
The Open Firmware screen will appear.
Type in the following:

* reset-nvram
* set-defaults
* reset-all

Your machine will restart automatically.
