Full BIOS read from an MX25L12805D chip on the Hellcat 13 Tiger Lake motherboard 19827-1. The 16 MB image matches the 128 Mbit capacity of that Macronix SPI flash. The five-digit dash-numbered board code follows the Wistron pattern used on many Dell systems. Technicians use the dump to recover boards that fail to POST or loop after corruption, writing it with an SPI programmer. Confirm the board number and revision on the PCB, and back up your own chip first to preserve service tag and ME data.
