BIOS image for a desktop board named H81M-V3-SI, with 2007 likely the firmware version, packed as a 4.59 MB RAR. The H81 designation points to Intel's H81 chipset for Haswell-era processors. Such a file is used to reprogram the board's SPI flash after a failed update or corruption that stops POST. The maker is not stated, so confirm the model on the PCB. Save a backup of the existing chip and check that the image fits the flash capacity before writing it with a programmer.
