Your NetWinder's web configuration system has two modes: User Mode, which is available to both normal users and the administrator, and Administration Mode, which is available only to the administrator and allows you to change various special configuration options.
To switch from User Mode to Administration Mode, simply click the words Switch to administration mode at the bottom of the User Mode screen. You may be asked to enter your password again. After that, you'll see this page:
Note: The on-screen highlight colour for Administration Mode is burgundy, while for User Mode it is blue, to remind you at all times of your current mode of operation.
