I have a new Dual PowerMac and would like to know how one does reset there firmware and what that does? Does it fix stuff like the P-Ram reset?



Please tell

    To reset: Reboot your Mac and hold down Command + Option + O + F. This will boot the Mac into Open Firmware. Then type in reset-nvram, then type reset-all. That will reset it and reboot the Mac.



    I don't recommend doing that unless you're actually having problems that running fsck and zapping the pram don't fix.

    And why don't you recommend doing this? what bad can happen? Does something bad happen also sometimes when one uses this way?
