Archive for the HP 250 G5 laptop on Compal board LA-D703P, marked as OK in the name, which suggests the contents were checked and found to work. At 4.36 MB it most likely holds a BIOS image for the main SPI flash. Compal codes in the LA-xxxxP format identify the PCB, so the number printed on the board must match before you write anything. Read and save the original chip with a programmer before flashing, and compare the image size with the flash capacity.
