Files usually needed for this board
- BIOS (full SPI chip dump, .bin)
- Schematic (PDF)
- Boardview (.brd / .bdv / .cad)
Typical reasons to reflash: no POST after a failed BIOS update, a corrupted BIOS chip after a power cut, or a board that powers on with no display.
Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.
