+	help
+	  Nyan Big is a Tegra124 clamshell board that is very similar
+	  to venice2, but it has a different panel, the sdcard CD and WP
+	  sense are flipped, and it has a different revision of the AS3722
+	  PMIC. The retail name is the Acer Chromebook 13 CB5-311-T7NN
+	  (13.3-inch HD, NVIDIA Tegra K1, 2GB).
