Raw 8.00 MB BIOS binary named only with the number 11243-1, which follows Wistron board numbering. No brand, model or revision is given, so identify the target by matching the board number on the PCB. An 8 MB image fits a 64 Mbit SPI flash and is written with an external programmer to recover corrupted firmware. Save the existing chip contents before writing, since system data such as serial and MAC may live there, and confirm the chip capacity matches the file.
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 @bioshub. Enginerys does not host this file.
