Zipped BIOS image for the Dell Inspiron 15z, model 5523, at 3.80 MB. The name does not include the motherboard number or revision, so confirm the board in your machine matches before using it. A dump like this is written to the SPI flash with a CH341A or similar programmer to recover from corrupted firmware, no display or boot loops. Always read and store the original chip first, since it carries the service tag, and check that the image size equals the flash chip capacity before erasing and writing.
