Firmware archive for the Dell Inspiron 15 3555, an AMD-based model, with Iris named in the title and motherboard number 15276-1. Numbers in this five-digit-dash format follow the Wistron scheme, so Wistron is likely the board maker behind the Dell. The 2.25 MB RAR holds the BIOS dump, which is written to the SPI flash with an external programmer when the laptop powers on with no display or loops on boot. Confirm the board number silkscreened on the PCB and back up the existing chip before programming.

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 →
