BIOS firmware archive for the Acer Veriton M4660G desktop, built on a board identified in the name as B360H5-M14, which points to an Intel B360 chipset platform. The RAR is roughly 14.7 MB, so it likely holds a full SPI image or several files. A technician typically writes such a dump to the motherboard flash chip with a CH341A or similar programmer to recover a dead or corrupted BIOS. Read and save the original chip contents first, and confirm the image size matches the chip capacity before programming.
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.
