BIOS file for the Biostar H81M-IDE desktop motherboard, stored as a 5.00 MB RAR. The H81 chipset places this board on Intel's LGA1150 platform, where firmware sits in an SPI flash chip. Technicians use such a dump to revive a board stuck without video or post after a bad update, by writing the chip with a programmer such as a CH341A. Confirm the model marking on the PCB, read and save the original chip before writing, and check that the extracted image size matches the chip capacity before programming.
