About BIOS & firmware dumps

A BIOS dump is a byte-for-byte image of the SPI flash chip on a motherboard. Repair technicians use a known-good dump to revive a board whose firmware is corrupted, or to replace a firmware image with a clean Management Engine region after a chipset swap.

A dump is tied to the exact board revision. Always match the full board number and revision, back up the original chip twice before writing anything, and move the serial number, UUID and Windows key (DMI data) from the old image to the new one.
