BIOS image for a board identified as ETH-B75, version 1.12, marked as fully working. The B75 token suggests an Intel B75 chipset desktop or mining-type board, but the name gives no manufacturer, so confirm the board identity yourself. A dump of this kind is written to the SPI flash with an external programmer when the board fails to post after a bad update. Save the original chip contents first and check that the image size matches the flash chip capacity before programming.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
