Novena PVT / Senoko DVT This post is coming to you from Novena PVT, running off of Senoko PVT on battery. In engineering, there are several different versions of pre-release hardware. Novena itself has gone through three: EVT (engineering verification test), DVT (design verification test), and PVT (production verification test). The first revision was very rough, and required several modifications to fix various problems. We weren't sure what we wanted to do with it, so it had a few unusual features.
