Original firmware dump read from a Winbond W25Q16BVSIG flash chip, tagged FW A03, for a Dell device the name does not identify further. The 2 MB size matches the 16 Mbit capacity of that chip, so the image should fit an identical part one to one. A small chip like this on Dell boards often holds EC or secondary firmware rather than the main BIOS. Confirm the chip marking and the board model before writing with a programmer, and keep a backup of whatever is currently on the chip.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
