BIOS image for the Gigabyte GA-H81M-S2PH, revision 1.0, in a 16.7 MB RAR. This Intel H81 board can carry a main and a backup flash under Gigabyte's DualBIOS design on some models, so check which chips are present and which one needs rewriting. The archive is meant for recovering a non-posting board by programming the SPI chip with an external programmer. Make sure the board revision on the PCB reads 1.0, back up the current chip contents, and confirm the image size fits the chip before writing.
