BIOS dump for board 15277-1 with the code LV115SK in the name, marked fully working and supplied as a 4.06 MB RAR archive. The five-digit dash-number pattern is typical of Wistron, an ODM building laptops for several brands, so the laptop brand is not stated. Extract the image, check its size against the SPI flash chip and back up the original contents before writing with a programmer. Verify the board number on the PCB before use.
