Microsoft has updated their WHQL certification requirements for Windows 8, and placed specific restrictions on ARM platformsthat will make it impossible to install non-Microsoft operating systems on ARM devices, and make it impossible to turn off or customize such security. Choice quotes from the certification include from page 116, section 20: 'On an ARM system, it is forbidden to enable Custom Mode. Only Standard Mode may be enabled' — which prevents users from customizing their security, and in section 21: 'Disabling Secure MUST NOT be possible on ARM systems' to prevent you from booting any other OSes.
