BIOS file for the Dell Inspiron 1525 with the Intel 965GM chipset, built on Wistron board 07211-3 with PCB number 48.4W002.031. The archive is small at 714 KB, consistent with the flash sizes used on boards of that generation. Technicians use it to reprogram the BIOS chip when the laptop will not start because of corrupted firmware. Match the board revision printed on the PCB and dump the existing chip before writing. A mismatched image size will not fit the chip.
