Boot Mapping System Dynamic Network Boot Order Update
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face challenges during operating system deployments in network mode, particularly when changes in BIOS boot order require reboots, leading to loss of authentication information and inefficiencies in network settings detection and initiation.
Innovation Solution
A boot mapping system that incorporates a service location protocol (SLP) to dynamically update the network boot order, allowing the system to boot regardless of boot order changes, and includes SLP servers within the install infrastructure to locate OS images based on selected network protocols, enabling secure and efficient OS deployment across various network clients without the need for reboots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If BIOS boot order is changed to add network devices, then network OS deployment is enabled, but system reboot is required which loses authentication information
Solution Approach 1:
The system performs preliminary authentication and obtains credentials before modifying the boot order. The authentication information is captured and stored temporarily in memory before the system reboots, ensuring it is preserved and can be reused after the boot order change without requiring re-authentication.
Solution Approach 2:
An intermediary component (such as a network boot agent or firmware module) is introduced to manage the boot order change and authentication process. This intermediary captures authentication credentials, preserves them through the reboot event, and reinstates them after the system restarts, thereby preventing information loss during the transition.
2Adaptability or versatility
If system reboots after boot order change, then network device boot is enabled, but deployment time increases
Solution Approach 1:
The system performs preliminary configuration of network boot parameters and preserves authentication credentials before rebooting. By preparing all necessary configurations in advance and maintaining them in volatile memory, the system minimizes the time required for re-initialization after reboot, thereby reducing overall deployment time.
Solution Approach 2:
The system maintains continuous preservation of authentication credentials and network configuration data across the reboot event. Rather than losing and re-acquiring this information after reboot, the system keeps it alive in memory, ensuring the useful action of authenticated network boot continues seamlessly without interruption or time loss.
3Ease of operation
If PXE boot is used for network deployment, then remote OS boot is enabled, but security is compromised
Solution Approach 1:
An intermediary authentication mechanism is introduced between the PXE boot process and the OS deployment. This intermediary validates credentials, establishes secure connections, and manages authenticated access to network boot resources, thereby maintaining the ease of remote boot while significantly improving security posture.
Solution Approach 2:
The system implements feedback mechanisms where authentication status is continuously verified during the network boot process. If authentication fails or credentials are invalid, the system provides feedback to halt the boot process or request re-authentication, ensuring that insecure or unauthorized PXE boot operations are blocked while maintaining secure deployment.

AI summary
A system, method, and computer-readable medium are disclosed for a boot mapping system. More specifically, in certain embodiments, BIOS of an information handling system includes a boot mapping system which allows the information handling system to boot up regardless of a boot order change in a network mode of operation or a BIOS boot order change. Additionally, in certain embodiments, the boot mapping system further includes a service location protocol (SLP) which locates operating system images based on the type of network protocol selected for deployment.
