BIOS firmware for the Dell Latitude 3150 notebook, Wistron motherboard 15264-1. Wistron numbers its projects with a five-digit code plus a revision suffix, printed on the PCB, and builds many Dell education and business models. This image is used to rewrite the SPI flash after a failed update or when the board shows no display. Read the original chip contents first so service tag data is preserved, then verify the file size matches the flash before programming with a CH341A or similar tool.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
