# BIOS
|
|
|
|
This repository includes official releases and beta versions of BIOS for various branches, as well as related tools.
|
|
|
|
- ⚠ Generally, you should only upgrade the BIOS of the same branch. Cross-branch upgrades should only be performed when testing different BIOS features.
|
|
- ⚠ Upgrading the BIOS across different branches will invalidate the Secure Boot keys.
|
|
- ⚠ Upgrading to the incorrect BIOS branch may result in some functions of the carrier board not working properly.

|
|
> - **SATA**: The interface configuration for this BIOS branch, with detailed configuration differences for each branch available in the README within the branch directory.
