BIOS image for a D725 laptop board built around the HM40 and MV chipset labels, Wistron number 08242-1M, compressed into an 868 KB ZIP. Five-digit numbers with a dash suffix follow the Wistron naming pattern. A dump of this size suits the small SPI flash on older boards and is used to recover units that do not post after corruption. Verify the board number on the PCB, read the original chip first, confirm the flash capacity matches the image, and verify after programming.
