Archive labelled IRIS BSW MB with board number 14279-1, a numbering style used by Wistron on its laptop motherboards. BSW most likely refers to Intel Braswell, but the name does not name the laptop brand or say whether the contents are a BIOS, schematic or boardview, so open it with WinRAR or 7-Zip to check. Compare the 14279-1 marking on the PCB with the archive before using anything from it. If it contains a firmware image, read and save the existing SPI chip contents first, and confirm the size matches.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
