BIOS package for the Dell Latitude E5430 with platform code QXW00 on the Compal LA-7903P board, revision 1.0, labelled A00. The RAR holds a firmware dump meant for writing to the SPI flash chip with an external programmer when the laptop powers on but shows nothing or does not POST. Read and keep the original contents first, check that the image size matches the chip, and confirm that the LA-7903P code on the PCB is the same.
