BIOS for the Acer Aspire V5-431 notebook on a Wistron motherboard numbered 11324-1, inside a 2.82 MB RAR archive. Wistron, a major Acer ODM, labels its boards with five-digit numbers followed by a revision digit. The dump serves to reprogram the SPI flash chip with an external programmer when the system fails to post or after a failed update. Read and preserve the original contents before writing, confirm the 11324-1 number on the board, and check that the image size fits the flash chip.
