BIOS for the Elitegroup ECS A55F-M4 desktop motherboard, version 2.0 as stated in the name, supplied as a 2.02 MB RAR and marked as tested OK. A55 refers to the AMD chipset family the board name indicates. The image is programmed onto the SPI flash chip with an external programmer when the board fails to POST after a bad update or firmware corruption. Check the board version printed on the PCB, read a backup of the existing chip and ensure the image size matches the chip capacity.
