Abstract
A method and apparatus for storing information in a memory device that can be retrieved and displayed in a display device without “bootup” of the computer system.
Claims19
An apparatus comprising:
- a first memory device to retain information;
- a circuit coupled to said first memory device, said circuit configured to initiate a video controller to transmit said information to a display in response to a predetermined event, wherein said circuit initiates said video controller without booting up a computer system.
A system comprising:
- a first bus;
- a central processing unit (CPU) coupled to said first bus;
- a memory device coupled to said first bus;
- a video controller coupled to said first bus and configured to control a display device;
- a microcontroller coupled to said memory device;
- a key to initiate said microcontroller to transfer data from said memory to said video controller for display, with said CPU is in a power off state.
3 more elements
A system comprising:
- a bus;
- a plurality of resource devices coupled to said bus including a video controller;
- a memory device coupled to said bus;
- a central processing unit (CPU) coupled to said bus and operable to operate in two modes, wherein
- in a first mode, said CPU is operable to power up and initialize said plurality of resource devices, and
- in a second mode, said CPU is operable to power up and initialize said video controller and using said video controller to transmit information retained in said memory device to a display device.
3 more elements
A method comprising:
- retaining information in a first memory device;
- initiating a video controller without booting up a computer system;
- and
- displaying said information on a display using said video controller.
