BIOS / firmware archive named only by the model code F5-573G-72XB, which corresponds to an Acer Aspire F5-573G configuration; no board number, revision or chip details are given. The 5.10 MB RAR probably contains a flash dump intended for SPI reprogramming. Since the same model can use different mainboards, read the board number off the PCB and compare it with the contents before writing. Always save a full read of the original chip first and verify the image size equals the chip capacity.
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.
