Firmware dump for the Dell Studio 1555, saved without a file extension and 2 MB in size. The name marks it as working and the suffix a12 likely indicates BIOS revision A12 in Dell numbering, while mobile 4 is unclear. A 2 MB file fits a 16-megabit flash chip. Check the chip capacity and the motherboard number before programming with an external programmer. Dump the original first to retain service tag information.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
