Raw 16 MB BIOS binary labelled 213224-1Q and marked OK, meaning it was reported as working. The number resembles the numeric board codes Wistron uses on Dell laptops, but no model is named, so verify the label on the PCB before use. A 16 MB file fits a 128 Mbit SPI flash chip. Read the existing chip and keep that backup, since it holds the service tag and other unique data, then program this image with a CH341A or similar programmer.
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 @jdbios_world. Enginerys does not host this file.
