Tweaking jumper on motherboard

Question

how do you tweak the jumper on a ibook g4 motherboard running 10.3.9. i wish to do this because i need to reset the firmware password

Answer 1

Essentially you have a computer with a secure password
set in firmware, no jumper would be likely a cure for this.
And both of these similar posts on this issue would require
the same answer; to attempt to see if a reset of the firmware
could be done so access to the system is possible.
In some computers, the physical access to the hardware,
the RAM, and the computer's internals, could allow one
to dump a firmware password. In some models, removal
of the RAM, was said to enable the owner an avenue to
reset the firmware password; but that path may have been
merely hearsay. I haven't the time now to research that one.
There was said to be a way to reset a firmware security
password via the Single-user mode and keying in the
correct word or letter sequences, and making that do it.
Then, restarting the computer with Single-User disabled.
Though I may be incorrect about this, I suggest it is possibly
an angle to at least look into. A general search on the topic:
' Mac OS X firmware reset in Single User mode ' - google:
[link|http://www.google.com/#hl=en&q=MacOS+X+firmware+reset+in+Single+User+mode&btnG=Google+Search&aq=f&oq=Mac+OS+X+firm ware+reset+in+Single+Usermode&fp=OlAWEoQSgPM]
There are a few evidently possible leads in the search page.
Hopefully this is the path to clearing the previous password
security in firmware in the computer.
Good luck & happy computing!
