BIOS and EC firmware for the Lenovo IdeaPad U160 ultraportable, Wistron mainboard 09938-1, compressed into a 1.59 MB RAR. The numbered code with a dash suffix is the Wistron pattern used on many Lenovo boards of that era. The pack covers the system BIOS and the embedded controller firmware, which handles power-on, battery charging and keyboard functions. Flash it with an external programmer when the laptop will not start, after reading the original chips to a backup file.
