Zipped BIOS firmware for the Acer Aspire 5920, with the token ZD1, most likely the mainboard project code, added to the name. No version or tested status is stated. Extract the archive to check whether it holds a raw chip dump for programming or a vendor update package. A raw dump is written to the BIOS flash with a programmer to recover a board that does not post. Check the board code printed on the PCB and the chip capacity, and back up the original first.
