BIOS dump for a Dell model labelled 3670, taken from a board numbered 17529-1, a pattern that follows Wistron's ODM numbering. The raw binary is 32.0 MB, which points to a 256 Mbit SPI flash or a combined image covering more than one chip. Technicians use such an image to recover a board that will not post after a corrupted update. Confirm the board number printed on the PCB, read and keep the original chip contents with a programmer first, and check that the chip capacity matches before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @L9BCM2MdAgNjNDk1. Enginerys does not host this file.

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 →
