32 MB BIOS image for the Dell 15-7510 on Wistron board 19844-1, reported as working. The size matches a 256 Mbit SPI flash chip, so the file can be written directly without trimming. Wistron uses the five-digit dash-suffix numbering on the boards it builds for Dell. Technicians use such a dump to revive boards with corrupted firmware after a failed update or chip fault. Read and archive the original chip before flashing, and confirm the PCB number matches 19844-1 to avoid an incompatible image.
