Firmware archive for an Acer Predator PO9-900 desktop, with no board number, version or flash chip size stated in the name. The 7.66 MB RAR most likely contains a BIOS image intended for reprogramming the motherboard's SPI flash with an external programmer after corruption or a failed update. Open the archive to inspect what it holds before use, and compare the board identifier printed on the PCB. Save a backup of the current chip contents and confirm the image size matches the chip capacity.
