BIOS image for the ASRock Z87 Extreme3 desktop motherboard, intended for an 8 MB SPI flash chip. It comes as a RAR archive for recovering boards that fail to start after a bad update or firmware corruption. Write it with an external programmer after reading and saving the contents of the existing chip. Check that the extracted image is exactly 8 MB so that it fits the chip, and confirm the model printed on the board matches before you commit the write.
