Raw 8 MB BIOS binary labelled for an Iris BSW motherboard numbered 14279-1, a format used by Wistron. BSW usually refers to the Intel Braswell platform, and Iris appears to be the project name. Being an uncompressed .bin of 8 MB, it suits a 64 Mbit SPI flash chip and can be written directly with a programmer such as a CH341A. Verify the board number on the PCB, read and keep the original contents, and check the chip capacity before writing.
