Solution Overview

Problem

In computer systems, damaged devices such as CPUs or DIMMs cannot be detected during the start procedure, leading to undetected anomalies that prevent timely repair or replacement.

Innovation Solution

A computer system with a BIOS unit that pre-stores a current device table, allowing it to detect and compare results during the start procedure, and issue an alarm if the detected information does not match the stored table, indicating an anomaly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the BIOS unit performs standard device detection during start procedure, then the system can identify device configuration, but damaged devices cannot be detected and anomalies remain hidden

Engineering Contradiction:

Improvedevice anomaly detection capabilityVSAvoiddetection mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-storing expected device information in a device table within the BIOS unit before the start procedure begins. During detection, the BIOS compares detected device parameters against this pre-stored expected values, enabling identification of damaged or anomalous devices without requiring complex real-time analysis mechanisms.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the BIOS unit continues start procedure without detecting damaged devices, then system booting is maintained, but timely repair or replacement of damaged devices cannot be performed

Engineering Contradiction:

Improvesystem booting efficiencyVSAvoidtime for device repair or replacement

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent implements feedback by having the BIOS unit compare detected device information against the pre-stored device table and provide immediate feedback when discrepancies are found. This feedback mechanism allows the system to identify damaged devices during the start procedure and alert users, enabling timely repair or replacement while maintaining normal system booting operations.

Inventive Principle:

Principle #23Feedback

3Ease of operation

If no device detection comparison is performed, then the start procedure remains simple and fast, but users cannot know whether devices are damaged

Engineering Contradiction:

Improvestart procedure simplicityVSAvoiddevice status information

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent applies self-service by having the BIOS unit automatically perform comparison between detected device parameters and pre-stored expected values, and automatically generate alarm information when discrepancies are found. This self-service mechanism provides device status information to users without requiring manual intervention or complex user actions, maintaining simplicity while providing necessary information.

Inventive Principle:

Principle #25Self-service

AI summary

A computer system and a detecting-alarming method thereof are provided. The computer system includes a device and a basic input/output system (BIOS) unit. The BIOS unit has a current device table. The BIOS unit detects the device of the computer system to obtain a detecting result in a start procedure, and compares the detecting result with the current device table. If the detecting result does not match the current device table, the BIOS unit gives an alarm.
