Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing BIOS systems in computer systems face challenges in efficiently managing storage space, particularly in the boot BIOS, due to the large size of the initiating display chip program, which limits the capacity for other essential programs when the system BIOS is damaged.

Innovation Solution

A method where the initiating display chip program is stored in a backup file on external storage media, loaded into memory, and executed when needed, allowing the boot BIOS to initiate the display chip, thereby freeing up space in the boot BIOS for other programs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the initiating display chip program is stored in the boot BIOS, then the display chip can be initiated when system BIOS is damaged, but the storage space of boot BIOS becomes insufficient for other essential programs

Engineering Contradiction:

Improvedisplay unit operation reliabilityVSAvoidboot BIOS storage capacity

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts the initiating display chip program from the boot BIOS and stores it in an external storage medium instead. This removes the large program from the limited boot BIOS space while maintaining the capability to initiate the display chip when needed, directly resolving the storage space insufficiency problem

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an external storage medium as an intermediary to store the initiating display chip program. This intermediary allows the program to be kept outside the boot BIOS while still being accessible when the system needs to initiate the display chip, solving both the storage space constraint and the reliability requirement

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the system BIOS is made updateable to increase I/O unit capabilities, then the system functionality is improved, but the risk of system BIOS damage increases

Engineering Contradiction:

ImproveI/O unit capabilityVSAvoidsystem BIOS integrity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent divides the BIOS system into two separate components: system BIOS and boot BIOS. The system BIOS can be updated to add new I/O capabilities, while the boot BIOS remains intact and unchanged, providing a reliable fallback if the system BIOS becomes damaged during updates

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent prepares a boot BIOS in advance that contains the initiating display chip program and other essential initialization code. This serves as a cushion or safety net that can be activated if the system BIOS becomes damaged, allowing the system to still function and enabling BIOS recovery

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A method and system for initiating a display chip in a computer system is provided, and the initiating system includes a non-volatile memory, an external storage media and a memory unit. A BIOS which is able to initiate the external storage media is stored in the non-volatile memory. First, a backup file is loaded into the memory unit from the initiated external storage media. Then, an initiating program is fetched from the backup file. Finally, the initiating program is executed to initiate a display chip of a computer system.
