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

395 Lincroft (CPU core, graphics, and memory controller) and Langwell IOH.
396 Unlike standard x86 PCs, Moorestown does not have many legacy devices
397 nor standard legacy replacement devices/features. e.g. Moorestown does
398 not contain i8259, i8254, HPET, legacy BIOS, most of the io ports.

786 Your processor must be a Pentium or newer to support this - check the
787 flags in /proc/cpuinfo for mce. Note that some older Pentium systems
788 have a design flaw which leads to false MCE events - hence MCE is
789 disabled on all P5 processors, unless explicitly enabled with "mce"
790 as a boot argument. Similarly, if MCE is built in and creates a
791 problem on some new non-standard machine, you can boot with "nomce"
792 to disable it. MCE support simply ignores non-MCE processors like
793 the 386 and 486, so nearly everyone can say Y here.
