BIOS firmware for the Biostar H81M-IDE motherboard, version 7.x according to the name, archived in RAR. The H81 chipset is part of the Intel LGA1150 Haswell platform. This dump is used to recover a board with corrupted firmware by writing the SPI chip with a programmer such as a CH341A. Since the name covers the 7.x board versions in general, check the exact version printed on the PCB, compare the image size with the chip, and save the original read before flashing.
