Motherboard flash dump for the Dell Vostro 1540, with DV15 CP UMA in the name, UMA meaning the integrated-graphics board version. The board follows the Wistron numbering scheme, number 10263-1. The rar archive is around 1.96 MB and should contain an image for the SPI BIOS chip. Repair shops write it with a programmer to bring back a board that will not post. Before flashing, read and save the existing contents, check that the board label matches, and confirm the image size fits the installed flash chip.
