Dell ThinOS 10.x Migration Guide
BIOS configuration details
The BIOS Common Configuration acts as a centralized settings page in ThinOS that consolidates all BIOS settings that are supported across all ThinOS 10.x devices. This feature ensures consistent BIOS configurations across devices using the same Active Directory in WMS.
To access the BIOS Common Configuration settings in WMS, go to .
The following are the key highlights:
- If a platform-specific BIOS configuration exists, that configuration is applied; otherwise, the common BIOS configuration is used.
- Platform-specific settings take precedence over common settings.
- Supports scalable BIOS configuration across many devices.
- Reduces manual effort during deployment by allowing BIOS settings to be pushed centrally.
- Enables easier onboarding of new platforms by falling back to a common configuration until platform-specific values are available.
NOTE:This feature is supported across all platforms. However, if a
platform includes a dedicated BIOS settings page, any changes made there overrides the BIOS
Common Configuration settings.
