BIOS archive for the Dunes board 15249-1, with SKLU in the name, which likely points to the Skylake-U platform. The name states the image is 16MB, matching a 128-Mbit SPI flash chip. The 15249-1 numbering follows the Wistron scheme, an ODM that builds boards for several notebook brands. Use a programmer to write the dump when the original firmware is damaged. Save the old chip contents first, check the PCB number before flashing, and verify the chip is a 16MB part, since a mismatched image will not fit.
