+# 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.
+
+## BIOS Naming Rule
+
+> Example:  
+> LP-BS-S70NC1R200-SR-A-SATA
+>
+> - **LP**: LattePanda
+> - **BS**: BIOS
+> - **S70NC1R200**: Internal version number for LattePanda Mu
+> - **SR**:
+>   - SR: Single Rank memory
+>   - DR: Dual Rank memory
+> - **A**: BIOS version number, with new versions sequentially labeled in alphabetical order
+> - **SATA**: The interface configuration for this BIOS branch, with detailed configuration differences for each branch available in the README within the branch directory.
+>   - No suffix: DFLT (Default) branch
+>   - SATA: SATA branch
+>   - PCIE: PCIE branch
+>   - MUSB: MUSB branch
+
+## File Description
+
+- Beta: Beta version BIOS, not specific to any branch, intended for professional developers to assess new features.
+
+- DFLT: Default version BIOS, which is the BIOS branch that comes pre-installed on the LattePanda Mu.
+
+- MUSB: A BIOS branch configured to maximize USB 3.2 10Gbps interface capabilities (coming soon).
+
+- PCIE: A BIOS branch configured to maximize PCIe 3.0 lane configurations (coming soon).
+
+- SATA: A BIOS branch that provides SATA interface signal.
+
+- Tools: Tools for BIOS maintenance.
