Part 09 of the BIOS Acer multi-volume RAR archive, 9.00 MB in size. This segment carries a portion of an Acer firmware collection and only becomes usable once all volumes are present and extracted together via WinRAR or 7-Zip. The name gives no model or board numbers. When restoring a machine from the unpacked images, check the motherboard number and revision first, back up the original SPI chip with a programmer, and ensure the dump 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 @bios_laptop. Enginerys does not host this file.
