Dell E7250 ZBZ0 LA-A971P BIOS U53 4mb-OK

BIOS .rar 2.69 MB Shared

BIOS dump for the Dell Latitude E7250 with Compal board LA-A971P, platform code ZBZ0, taken from the flash chip at position U53. The name marks it as 4 MB and as working. Compal LA-numbered boards share this naming style across many OEMs. Use a programmer such as a CH341A to write the image to a matching 4 MB SPI chip. Read and keep the original contents first, since they hold the service tag, and confirm the board number on the PCB is LA-A971P.
