Firmware for the Dell Inspiron 1525 DS2 Intel platform with the 965GM chipset, stored in a 787 KB RAR. DS2 is the Wistron project name for this laptop family, and the 965GM marking points to the integrated-graphics build. Repairers flash such images onto the SPI BIOS chip with a hardware programmer to recover a dead or bricked board. Before writing, dump and archive the original contents, check that the image length matches the chip, and confirm your board uses the same chipset variant.
