A new way to resuscitate a dead battery
Authored by: XiMac on Jul 21, '03 11:01:13AM

If I'm not very, very wrong, this trick reset the open firmware to the original-on-factory OF. Be aware that the PowerBook users that needs an OF update to run OSX must update again the Open Firmware before restart on OSX.

This doesn't revert the machine to old firmware (how could it?) It just resets the values to their default settings.

No, resetting a Mac's "Open Firmware" does not reset the Mac's "firmware" chip. This is an unfortunate case where two different things have similar names. The firmware chip that gets updated by Apple's firmware updaters, is a different chip than the one where the Open Firmware settings are stored. After you do an Open Firmware reset, you don't have to re-apply the latest firmware update to maintain OS X compatibility.
