	  Moorestown is Intel's Low Power Intel Architecture (LPIA) based Moblin

	  Internet Device(MID) platform. Moorestown consists of two chips:

	  Lincroft (CPU core, graphics, and memory controller) and Langwell IOH.

	  Unlike standard x86 PCs, Moorestown does not have many legacy devices

	  nor standard legacy replacement devices/features. e.g. Moorestown does

	  not contain i8259, i8254, HPET, legacy BIOS, most of the io ports.
