Re: Stephen Curry and both FW ports
Perhaps one of these suggestions will help:
1) Pull ALL cables (pwr, USB, etc) and let sit for 10 minutes; reconnect &
restart. 2) press the SMU reset button (ONCE) on the logic board; it is
halfway between the lowest RAM slot and the bottom edge of the logic board.
3) Zap the P-RAM: After the startup tone, hold down <cmd><opt><p><r> until
3 additional startup tones are heard, then release the 4 keys. Note: the
<cmd> key is next to the space bar and may have an apple or "propeller" on
it, while the <opt> key is next to it and may have the word "option"
and/or "alt" on it. 4) Open Firmware reset for PPC: After the startup tone,
hold down <command><option><o><f> until the text screen is visible. When
text can be entered, type the following commands, followed by the <return>
key:
reset-nvram set-defaults reset-all (the Mac will boot up after this command
is entered

I have revived FireWire ports with this Open Firmware action:
Boot into Open Firmware:
Restart holding command-option-of
At the Open Firmware command line key in:
reset-nvram <press return>
reset-all <press return>
Your MAChine should restart and your FireWire ports may be available.
