COMPAQ PRESARIO 720EA NOTEBOOK BATTERY CONTROLLERKBC DRIVER
The firmware includes an ACPI name space, i.
The hierarchical name space is constructed Compaq Presario 720EA Notebook Battery ControllerKBC a "click and drag" methodology, and is represented in the windows interface as a iconographic tree structure. From the root of the tree structure are branches for general purpose events, processor power control, sleep states, the system bus, and temperature controls. The system bus has branches for devices located thereon, and the devices have branches for folders containing current resource settings, hardware identification, possible resource settings, and set resource settings information.

The utility prompts the OEM programmer during the creation of the name space for information required to complete the specification of the details of the system. The utility provides a large number of default components, from the level of the entirety of the hierarchical tree structure to the level of the individual devices. Using a recursive process, the constructed hierarchical tree structure is mapped to ASL source code with a structure roughly mirroring that of the tree structure. In general, the recursive process creates a name statement, opening brace, body and closing brace for each item, and child items within the Compaq Presario 720EA Notebook Battery ControllerKBC of a parent item fall within the body of the parent item.
There are several drawbacks to allocating the Compaq Presario 720EA Notebook Battery ControllerKBC management, thermal management, battery management and plug-and-play functions to the BIOS firmware. For example, the BIOS is only accessed at boot-up and, therefore, these functions cannot be modified or updated subsequent to boot-up. Any alterations of the hardware subsequent to the boot-up cannot be handled by the BIOS. Another drawback is that the BIOS firmware and the hardware are strongly coupled. The evolution of the BIOS and the hardware cannot be independent and their ship cycles must be synchronized.
Furthermore, there is limited space available in the BIOS firmware, so only relatively simple power management policies could be implemented. The specialized knowledge required to generate the BIOS code for a particular device is not only dependent on the device, but is also dependent on the platform on which it is to be installed, and the other devices with which it is to Compaq Presario 720EA Notebook Battery ControllerKBC.

Generating error-free code is of particular importance. Furthermore, the BIOS is fundamental to the operation of the machine, so its reliability, size and performance is critical. Consequently, the development of the BIOS is one of the most serious scheduling risks for an OEM due to the extensive testing that must be performed to insure its quality.
The computer system having an operating system with predefined devices including a system bus and a processor and the BIOS firmware including a pointer to Compaq Presario 720EA Notebook Battery ControllerKBC root of the hierarchical tree structure corresponding to the power control and the data control information. The utility includes means for defining a first scope for the root of the hierarchical tree structure and means for attaching a bus object within the first scope of the root of the hierarchical tree structure. The bus object corresponds to the system bus of the computer system. The utility also includes means for defining a second scope for the bus object and means for attaching a processor object within the second scope of the bus object thereby indicating that communications to the processor of the computer system are routed via the system bus.
The processor object corresponds to the processor of the computer system.

Preferably, the utility generates a root of the tree corresponding to the address Compaq Presario 720EA Notebook Battery ControllerKBC the BIOS firmware where a pointer to a data structure containing the power control and the data control information is located. A bus object representing the computer's system bus can be attached to the tree, and a device object representing a particular device can be attached to the bus object, indicating communications to the device are routed via the bus object. The device object has a hardware identification folder, current resource settings folder, possible resource settings folder, set resource settings folder, power set folder and power resource folder. The hardware identification folder contains a number that uniquely identifies the type and manufacturer of the device.
Access Compaq Presario 720EA Notebook Battery ControllerKBC the current resource setting folder by the computer system informs the system of current resource settings of the device. Access of the possible resource settings folder by the system informs the system of possible resources utilized by the device. Access of the set resource settings folder by the computer system directs the system to set the resources utilized by the device. The power set and power resource folders have associated values corresponding to a power state level of the device, and access to the power set folder by the system directs the system to place the device in that power state level.
