Dell Precision M2400 (Mid 2008) - Manual (Page 17)

Remote Configuration Enable/Disable
The selectable options are Enable and Disable. If Remote Configuration is disabled, the menu options underneath are still
displayed, but are not be used until Remote Configuration is enabled.
This option cannot be modified once the setup and configuration process is in process. This parameter can only be modified
while the computer is in the factory default or un-provisioned state.
Enabling/disabling remote configuration causes a partial un-provision if the setup and configuration is In-process.
Manage Certificate Hashes
Select the Manage Certificate Hashes option under the Remote Configuration menu to display the Manage Certificate
Hashes menu. Four default hashes are available from the factory. Hashes can be deleted or added per customer needs.
