BIOS firmware for the Intel NUC6i3SYH kit and its NUC6i3SYB board, from the SYSKLi35.86A release family, which identifies the Skylake NUC firmware line. The 6.85 MB RAR can be used to recover a mini PC that no longer posts or to restore a corrupted SPI image. Intel normally offers recovery through its own update tools, but a programmer helps when the board is dead. Back up the existing chip contents first and verify the image fits the flash capacity before writing.
