Firmware for the Acer V3-471 in .fd format, 4.00 MB, the size of a 32 Mbit SPI flash. FD files are typically raw flash descriptor images that a programmer can write once the size matches the chip, though some are BIOS-region update files rather than full dumps. Inspect it with a hex editor or UEFI tool before use. The name gives no board number, so confirm the PCB revision. Save the original chip contents first, as they hold the ME region and system identifiers.
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 @ComputerBIOSBinFile. Enginerys does not host this file.
