Firmware-Level Hardware Device Disabling with Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manually disabling multiple computer devices is time-consuming and prone to errors, particularly in secure environments where compliance with regulations is critical.
Innovation Solution
A method and apparatus that enable the disabling and enabling of computer hardware devices on a firmware level during a reboot, with automatic validation and user-indication of the status, ensuring compliance with secure area regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual disabling of computer devices is performed, then device control is achieved, but time consumption increases and errors occur
Solution Approach 1:
The system performs preliminary action by automatically selecting and configuring devices for disabling before the actual disabling operation. The predetermined subset of devices is identified and prepared for disabling during the reboot process, eliminating the need for manual selection and reducing human error while saving time.
Solution Approach 2:
The computer system performs self-service by automatically disabling the predetermined subset of hardware devices during reboot without requiring manual user intervention. The validation process also runs automatically to verify disabling status, making the entire process autonomous and eliminating time-consuming manual operations.
2Reliability
If manual disabling of multiple devices is performed, then device control is achieved, but complexity of operation increases
Solution Approach 1:
The system segments the device disabling process by dividing all hardware devices into a predetermined subset that will be automatically disabled. This segmentation allows the system to handle multiple devices through a single automated operation rather than requiring manual control of each device individually, simplifying operation while ensuring regulatory compliance.
Solution Approach 2:
The reboot process serves multiple functions: it enables the computer to automatically disable devices, validate their disabling status, and ensure compliance with secure area regulations. This multi-functionality consolidates what would otherwise require multiple separate manual operations into a single automated process, greatly improving ease of operation.
3Reliability
If validation is performed to ensure devices are disabled, then reliability is improved, but additional processing time is required
Solution Approach 1:
The validation process is performed as a preliminary action during the reboot sequence, immediately after device disabling is attempted. By incorporating validation into the reboot flow rather than performing it separately afterward, the system minimizes additional processing time while ensuring reliable verification of device disabling status.
Data Source
AI summary
A method of operation is provided during which a plurality of hardware devices of a computer are disabled on a firmware level during a reboot of the computer in response to receiving a disable command prior to the reboot. A validation is run to determine whether or not the hardware devices are disabled. A validation signal is provided indicative of whether or not the hardware devices are validated as being disabled.
