BIOS backup image for the Acer Nitro V15, taken from the Quanta board DA0ZYPMBAF0 at revision F. The BKP prefix indicates a dump read from a working machine rather than a vendor update file. At 32 MB it matches a 256 Mbit SPI flash chip, and an image of a different size will not fit the chip. Write it with a programmer such as a CH341A after saving the original contents, and confirm the board number and revision printed on the PCB match before flashing.
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 @acheibios. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
