Boot System Rescue OS via IO Chip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional boot systems require additional hard disk capacity and recovery discs to recover a computer system from malfunctions, increasing costs and complexity, especially when recovery discs are lost or the disc drive cannot read data.
Innovation Solution
A boot system comprising an IO chip and a memory device with a rescue OS, where the BIOS reads and executes the rescue OS from the memory device via the IO chip to boot an electronic device, optionally including a repair utility for checking and repairing the hard disk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a recovery disc and disc drive are used to boot the computer system for recovery, then the computer system can be recovered from hard disk or OS damage, but the system complexity increases and recovery fails if the disc drive cannot read data
Solution Approach 1:
The invention extracts the rescue OS from the external recovery disc and integrates it into the internal memory device of the computer system. This eliminates the dependency on external recovery discs and disc drives, reducing system complexity while maintaining recovery capability. The rescue OS is stored locally in the memory device and can be directly accessed by the BIOS through the IO chip.
Solution Approach 2:
The invention introduces an IO chip as an intermediary component that enables the BIOS to directly access and read the rescue OS from the memory device. This intermediary mechanism provides a reliable boot path that bypasses the need for disc drives, improving recovery reliability while simplifying the overall system architecture.
2Reliability
If additional hard disk capacity is allocated to store backup OS, then the computer system can switch to backup OS when primary OS malfunctions, but the cost of the computer system increases
Solution Approach 1:
The invention makes the memory device serve multiple functions: it acts as both the primary storage for the operating system and as the backup storage for the rescue OS. This multi-functionality eliminates the need for separate backup storage capacity, reducing the quantity of hard disk capacity required while maintaining the ability to recover from OS failures.
Solution Approach 2:
The invention merges the rescue OS storage function with the existing memory device, combining what were previously separate storage requirements into a single integrated solution. This consolidation reduces the total hard disk capacity needed while providing both primary and backup operating system capabilities.
3Reliability
If recovery disc is lost or disc drive cannot read recovery disc data, then the computer system cannot be successfully recovered, but using recovery disc is a conventional practice
Solution Approach 1:
The invention performs preliminary action by pre-loading the rescue OS into the memory device during system manufacturing or initialization. This ensures that the rescue OS is always available in the system's internal storage, eliminating the risk of losing external recovery discs or having disc drive reading issues. The BIOS can directly access this pre-positioned rescue OS through the IO chip whenever recovery is needed.

AI summary
Boot systems and methods are provided. The boot system includes an IO (Input/Output) chip, a memory device, and a BIOS (Basic Input/Output System). The memory device is coupled to the IO chip, and includes at least a rescue OS (Operating System). The BIOS reads the rescue OS from the memory device via the IO chip, and boots an electronic device based on the rescue OS.
