BIOS (full SPI chip dump, .bin)
EC / KBC firmware, if the board uses a separate EC chip
Schematic (PDF)
Boardview (.brd / .bdv / .cad)

Typical reasons to reflash: no power or no display after a failed BIOS update, a BIOS/supervisor password lock, or a corrupted Intel ME region.

Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.
