BIOS dump for the Dell Latitude 7275 tablet, board LA-C321P, with the name noting a 16 MB image, supplied in a 5.29 MB RAR. The LA-xxxxP format belongs to Compal, the ODM that built this board for Dell. A 16 MB file needs a 128 Mbit SPI flash, so verify the chip on the board before programming. Technicians use such dumps to fix no-POST, boot loops or corrupted firmware. Read and keep the existing contents first, as service tag and configuration data are stored in the chip.
