BIOS firmware package for the Acer Aspire V5-471, built on the Wistron board code-named HUSK with board number 11309-2. The zip holds roughly 6 MB of data, so it may contain more than a single flash image; inspect the contents before programming. Five-digit numbers with a dash revision are the Wistron pattern, so confirm the 11309-2 marking on the PCB first. Read and save the original SPI chip with a programmer such as a CH341A before writing, and check that the image size matches 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.
