BIOS image archive for a board marked EM_IC819_200B, packed as RAR and described in the name as a 16MB dump. The 16MB figure points to a 128Mbit SPI flash chip, so check the chip marking on the board before writing anything. Technicians use such dumps to recover a laptop that powers on without display or is stuck in a boot loop, writing the image with a CH341A or similar programmer. Always read and save the original chip contents first, and verify the board code printed on the PCB matches EM_IC819_200B.
