A computer may comprise a processor and first storage device coupled to the processor. The first storage device contains a basic input/output system (BIOS) executable by the processor. The system may also comprise a second storage device coupled to the processor. The second storage device may contain a management interface usable by an operating system to access the BIOS. A plurality of interface files may also be provided, each interface file being usable by the management interface to access the BIOS and each interface file defining one or methods for use by the interface or BIOS. Upon execution of the BIOS, the processor is to determine a configuration of the system and, based on the determined configuration, to select a particular interface file for use during run-time.

Plurality of interface files usable for access to BIOS

A BIOS controlled peripheral device port power device is described. The device includes a processor and at least one peripheral device port. The processor powers up a host controller in preparation for the processor to enter a sleep state. The processor also places the processor in the sleep state after the host controller is powered up. The processor also selectively powers the at least one peripheral device port by the host controller when the processor is in the sleep state according to at least one setting stored in the processor.

BIOS controlled peripheral device port power

A device including an interface component configured to couple the device to a computing machine, a storage component configured to store a device driver for the device, and a driver application executed from the storage component and configured to identify the device as a storage device if a device driver has not been loaded onto the computing machine and bad the device driver onto the computing machine in response to the device coupling to the computing machine.

Loading a device driver from a device

A system may comprise a processor () and first storage device () coupled to the processor. The first storage device contains a basic input/output system (BIOS) () executable by the processor. The system may also comprise a second storage device () coupled to the processor. The second storage device may contain a management interface () usable by an operating system to access the BIOS. A plurality of interface foes () may also be provided, each interface file being usable by the management interface to access the BIOS and each interface file defining one or methods for use by the interface or BIOS. While executing the BIOS, the processor determines a configuration of the system and, based on the determined configuration, selects a particular interface file for use during run-time.

A computing device () has a processor () and at least one peripheral device port (-to-). The processor () is configured to selectively power the at least one peripheral device port (-to-) when the processor () is in a sleep state () according to at least one setting stored by firmware () of the processor ().

A system includes an HDCP-over-USB controller including an HDCP module for encrypting or decrypting video data according to an HDCP standard prior to transmission or display of said video data.

HDCP video over USB

A method including initializing at least one component of another computing machine in response to the other computing machine coupling to a computing machine, loading a component driver onto the computing machine for at least one of the initialized components, and configuring the computing machine to use the component driver to control at least one of the initialized components of the other computing machine.

Configuring a computing machine to use a component driver to directly control at least one of initialized hardware components of another computing machine

A method includes searching a peripheral storage device for a key during a firmware boot process of a computer system. Operating system access to the peripheral storage device is disabled if the key exists. Another method includes disabling operating system access to a peripheral storage device coupled to a pre-determined attachment point of a computer system during a firmware boot process of the computer system.

Firmware exclusive access of a peripheral storage device

In one embodiment, a circuit to indicate a match between a user-selectable power setting and an input voltage, comprises a first circuit node connected to a power source at an input voltage level, a second circuit node, a switch to switch the first circuit node and the second circuit node between a first position associated with a first voltage and a second position associated with a second voltage, and a first indicator coupled to the first circuit node and the second circuit node and activated when the switch is set in a position that corresponds to the input voltage level.
