Files usually needed for this board
- EFI firmware (full SPI ROM dump)
- Schematic (PDF)
- Boardview (.brd / .bdv / .cad)
Typical reasons to reflash: no boot or no chime after a firmware update, a firmware (EFI) password lock, or a corrupted ROM after liquid damage.
Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.
