Resetting an unknown password is only for the administrator.
The install disk is only used for resetting the administrator password when nobody can remember the password.Is there a way to change the password on a power mac G4 without the install disk.?Not really. If you have any startup disk, like a Nortons Anti Virus etc., just so you can get past the log in, it should work.
