The disclosed embodiments provide a system that drives a display from a computer system. The system includes a first hardware path for controlling a backlight of a display of the computer system. The system also includes a second hardware path for controlling the backlight. Finally, the system includes a backlight controller that enables use of the first and second hardware paths in controlling the backlight from the computer system.

A method and apparatus are provided for supplying a reliable and maintainable operating system in a net-booted environment. According to one embodiment, a network computer (NC) client boots from a boot image provided by an NC server. The boot image includes information identifying the location of one or more system volumes on the NC server that contain operating system software. In response to an attempt to modify the contents of the one or more system volumes, the NC client causes information identifying the modification to be recorded on the NC server separate from the one or more system volumes in a storage area associated with the NC client.

A waveform generator generates LED signal values that define an LED waveform and period. Each signal value is scaled by a particular scaling value to scale the amplitude of the LED waveform. The scaled LED waveform is then transmitted to an LED to cause the light emitted by the LED to pulse at a variable brightness.
