Working BIOS dump for the ThinkPad X1, project code LMQ-1, on Wistron board 12298-2, sized for a 16MB SPI flash. The uploader marks it as fully tested. Technicians flash such an image to revive a board with a corrupted firmware region or after replacing the flash chip. The number follows Wistron's five-digit plus revision format. Before programming, dump and archive the existing chip contents, since serial and machine data live there, and confirm the chip is genuinely 16MB so the file fits.
