Acer Aspire 5920 BIOS image, 512 KB binary, with no board number or version in the name. A 512 KB size matches a 4 Mbit flash chip, which differs from the 1 MB MB6G0 dumps listed for the same model, so it likely holds only the BIOS region or suits a board with a smaller chip. Check the chip marking first. Program with an external flasher such as a CH341A, keep a backup read of the original, and confirm the motherboard version before writing.
