Working BIOS image for the Acer B75H2-AM2 desktop board, based on the Intel B75 chipset and labelled as one hundred percent working. Note that the AM2 suffix distinguishes it from the B75H2-AM, so check the board label carefully. The file is meant for flashing the SPI BIOS chip with an external programmer to recover a board that will not POST. Save the original chip contents before writing, and make sure the image size matches the capacity of the flash chip fitted.
