BIOS for the ASUS H61M-K desktop motherboard, in a 3.84 MB RAR, with no revision or chip details given in the name. The H61 chipset serves LGA1155 processors, and full SPI dumps for it usually contain both the BIOS and ME regions. Several versions of this board exist, so compare the revision printed on your PCB with any notes inside the archive. Read the original chip with a programmer and keep a copy before flashing, and check that the dump size equals the flash chip capacity.
