Apple PowerBook Password Security Control Panel Vulnerability

Boot the laptop from an emergency startup disk. The password dialog will appear. Select 'Cancel'. The laptop will be usable, but the hard drive and it's contents will not. However, Norton Disk Editor can be used even on unmounted drives. Using it or a comparable product, change the byte at offset 3 of the 'aaaaaaaaAPWD' file from 01 to 00 to disable the security feature. Reboot from the hard drive.
