Memory Slot Enablement via Identifier Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer systems often fail to automatically enable memory module slots after a repair action, leading to forgotten slot enablement and increased maintenance costs due to user error, resulting in system downtime.
Innovation Solution
A method that determines disabled memory module slots during the boot process, retrieves and compares memory module identifiers, and enables disabled slots if they do not match previously stored identifiers, using non-volatile memory to maintain configuration data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the BIOS manually enables memory module slots after repair, then the slot can be enabled, but the process is complex and prone to user error
Solution Approach 1:
The system automatically detects replaced memory modules and enables their slots without user intervention. The BIOS compares current memory module identifiers with previously stored identifiers, and when a mismatch is detected indicating a repair action, the system automatically enables the disabled slots, eliminating the need for manual user configuration.
Solution Approach 2:
The system implements a feedback mechanism by storing memory module identifiers in non-volatile memory and comparing them during boot-up. When the BIOS detects that identifiers have changed (indicating a memory module replacement), it receives feedback about the repair action and automatically responds by enabling the appropriate slots.
2Productivity
If the technician manually enables slots through BIOS menus, then the new memory module can be utilized, but maintenance time increases
Solution Approach 1:
The system performs preliminary actions by storing memory module identifiers in non-volatile memory during normal operation. Before the actual repair is needed, the system has already captured the original identifiers, so when a replacement occurs, the comparison and automatic enablement can happen immediately during boot-up without requiring technician intervention.
Solution Approach 2:
The system automatically detects and recovers from memory module replacements without requiring technician time. By comparing stored identifiers with current ones and automatically enabling slots when replacements are detected, the system eliminates the need for manual BIOS configuration, reducing maintenance time and increasing system uptime.
3Reliability
If the system disables slots after memory module failure, then system stability is maintained, but the slots remain inaccessible after repair
Solution Approach 1:
The system dynamically adjusts slot enablement status based on detected conditions. Slots are disabled when memory module failures are detected to maintain system stability, but the system automatically re-enables them when replacements are detected through identifier comparison, allowing the system to adapt to repair actions without manual intervention.
Solution Approach 2:
The system uses feedback from memory module identifier comparisons to dynamically control slot enablement. When identifiers match, slots remain in their original state; when identifiers differ (indicating replacement), the system receives feedback and automatically enables the slots, balancing stability with adaptability.
Data Source
AI summary
Methods, systems, and products are disclosed for enabling memory module slots in a computing system after a repair action, the computing system having a plurality of memory module slots and having at least one memory module installed in one of the memory module slots, that includes: determining, during a boot process for the computing system, whether any of the memory module slots are disabled; and if any of the memory module slots are disabled: retrieving, for each memory module installed in one of the memory module slots, a memory module identifier for that memory module, retrieving, from non-volatile memory of the computing system, previously stored memory module identifiers, determining whether the retrieved memory module identifiers match the previously stored memory module identifiers, and enabling the disabled memory module slots if the retrieved memory module identifiers do not match the previously stored memory module identifiers.
