BIOS archive labelled Acer for the H61H2-M6 motherboard version 2.0, an ECS-made Intel H61 board that Acer used in some of its desktops. Being an OEM image, it may carry Acer branding and settings that differ from retail ECS firmware. The 2.89 MB RAR is meant for chip-level recovery with an external SPI programmer. Check that the PCB revision reads 2.0, read and store the current chip contents before erasing, and confirm the image matches the chip size.
