Abstract

Systems that have HDD with passwords typically require the user to be physically present enter the password to boot the system. This prohibits remote maintenance of the systems since it is not possible to boot the system without being physically present and having knowledge of the hardfile password. This disclosure describes methods that will permit the system to be booted for maintenance without being present or without knowledge of the hardfile password.

Method to Boot a System with Hardfile Password

Systems that have HDD with passwords typically require the user to be physically present enter the password to boot the system. This prohibits remote maintenance of the systems since it is not possible to boot the system without being physically present and having knowledge of the hardfile password. This disclosure describes methods that will permit the system to be booted for maintenance without being present or without knowledge of the hardfile password.

The methods are:

1) BIOS provides an option to allow a user to select to boot without unlocking the HDD password.
2) BIOS can detect if this is a remote wake event (modem ring, LAN, timer, etc.) and will bypass

the

prompt for the HDD password
3) BIOS could set a timer.

For method one, BIOS will display a skip option when prompting for the password. If the user desires to continue booting but leave the drives locked, or does not know the drive password, but needs to boot the system for maintenance, the user could press a key (for instance the <ESC> key) to bypass prompting and unlocking the HDD(s). For method two, BIOS could detect that the POST process was initiated via a remote wake or a timer wake up and bypass the prompt for the HDD password. For the third method, BIOS would start a timer when the prompt for HDD password is displayed. If no user input is received within the specified time, the system would automatically boot without unlocking the HDDs. It would al...
