BIOS dump for the Inspiron 14z 5423 DMB40 board, and the name specifies the Intel motherboard version. The archive is 3.70 MB and is meant for reprogramming the SPI flash with a hardware programmer when the system will not boot. A dump marked as Intel should only go onto a board with the same platform, so confirm the chipset and the PCB label against the one you are repairing. Always back up the existing chip contents before writing, so the original data such as the service tag can be restored if needed.
