## BIOS Naming Rule
------
> Example:
> LP-BS-S70NC1R200-SR-A-SATA
>
> - **LP**: LattePanda
> - **BS**: BIOS
> - **S70NC1R200**: Internal version number for LattePanda Mu

## Naming Rule
## File Description
### New Naming Scheme (2025-12 and later)
**Format**
`S70NC1R200-[Memory]-[Version][-Variant].bin`
- **S70NC1R200**: Platform identifier (LattePanda Mu N100/N305)
- **Memory**:
- `8G` = 8GB RAM
- `16G` = 16GB RAM
- **Version**:
- `A`, `B`, `C`... (incremented alphabetically for each new release)
- **Variant** (optional):
- *(no suffix)* = Default (PCIe)
- `SATA` = SATA branch
**Examples**
- `S70NC1R200-8G-A.bin` → 8GB, Default (PCIe)
- `S70NC1R200-16G-A-SATA.bin` → 16GB, SATA
**Notes**
- New scheme is simplified and user-oriented.
- **All subsequent updates will follow this naming convention.**
### Legacy Naming Scheme (2024 Initial Release)
**Format**
`LP-BS-S70NC1R200-[Rank]-[Version][-Variant].bin`
- **LP**: LattePanda
- **BS**: BIOS
- **S70NC1R200**: Platform identifier(LattePanda Mu N100/N305)
- **Rank**:
- `SR` = Single Rank (corresponds to 8GB models)
- `DR` = Dual Rank (corresponds to 16GB models)
- **Version**:
- `A`, `B`
- **Variant**:
- *(no suffix)* = Default (PCIe)
- `SATA` = SATA branch
**Example**
- `LP-BS-S70NC1R200-SR-B.bin` → 8GB, Default (PCIe)
- `LP-BS-S70NC1R200-DR-B-SATA.bin` → 16GB, SATA
### Mapping: Legacy → New Naming
- `SR``8G`
- `DR``16G`
**Examples**
- `LP-BS-S70NC1R200-SR-B.bin``S70NC1R200-8G-A.bin` (newer)
- `LP-BS-S70NC1R200-DR-B-SATA.bin``S70NC1R200-16G-A-SATA.bin` (newer)

## Folder 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.
