BIOS package of 1.46 MB for the Gigabyte GA-H61M-USB3-B3 at board revision 1.1, distributed as a RAR archive. The board is based on the Intel H61 chipset. Technicians use such images to recover a motherboard that fails to post after a bad update, either by external SPI programming or through the backup BIOS mechanism. Revisions of this model have separate firmware, so check that the PCB reads rev 1.1, save the original contents before writing and verify that the file size suits the installed flash chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
