BIOS dump for Wistron board 213047-1, a 32 MB file with no extension that the name marks as working. At 32 MB it suits a 256 Mbit SPI flash chip, so check the chip marking before writing, because a smaller part will not hold it. Technicians use such a clean image to recover boards with corrupted firmware, a no-POST fault or a lost configuration, writing it with an external programmer. Save a full read of the original chip first, as it holds board-specific data such as the serial number and service tag.
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 @schematiclaptopramkushwaha. 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 →
