A standards organization has created a boot environment for tablets and PCs that could potentially run a 64-bit version of Windows RT.
The UEFI (Unified Extensible Firmware Interface) Forum on Wednesday announced that its boot firmware specifications will now support ARMv8, a 64-bit processor architecture announced by ARM in 2011. ARM’s processors are used in most smartphones and tablets, and chip makers such as Nvidia and Samsung are expected to release 64-bit processors for smartphones and tablets in the future.
Microsoft on Windows 8 and RT requires PCs and tablets to carry a feature called Secure Boot, which prevents a system from being hijacked. The Secure Boot environment is based on UEFI firmware and ARM has already said it is working with Microsoft to develop a 64-bit version of Windows for ARM-based devices. However, it is not yet clear when the OS will come out.
