BIOS archive, 2.32 MB, for a ZX-H61C motherboard at version 1.2, an Intel H61 chipset board for LGA1155 processors. H61 boards use SPI flash that also holds the Management Engine region, so a full dump restores both. Program it with a CH341A or similar after reading and saving the original chip, which also preserves the board MAC address. Confirm the PCB reads ZX-H61C v1.2 and that the image size matches the flash chip, usually several megabytes on this platform.
