Dell BIOS package for the Inspiron 3451 and 3551, version A05, with IRIS in the name, likely referring to the board or project code name, shipped as a 4.23 MB RAR archive. Dell labels BIOS releases with Axx numbers, so A05 identifies the firmware revision. A technician uses such an image to restore a board with corrupted firmware via an SPI programmer. Before writing, back up the original chip so the service tag and keys can be preserved, and confirm the image size fits the flash chip fitted on the board.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
