BIOS image for the Gigabyte GA-H55M-USB3 at board revision 2.0, in a 6.18 MB RAR. The board uses the Intel H55 chipset. Revision 2.0 may differ from 1.0 in components and firmware, so match the REV marking on the PCB before writing. The dump is used for reprogramming the SPI flash with an external programmer when the board fails to post due to corrupt firmware. Save a backup of the original contents first, and ensure the image size matches the 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.
