Lenovo S230u (Twist) Hotfix 1

The Lenovo S230u, more commonly known as the Twist, includes a solid state cache drive in order to boost performance over standalone HDD systems. The initial NMU image released in the fall of 2013 with version 440902 did not properly enable this cache drive. This hotfix also applies to the newly released Windows 8.1 image with version 441000. Installing this hotfix will enable the cache drive and, in turn, boost overall system performance.
