Access UEFI Services At Runtime

My friend Vincent Zimmer put together a great summary article showing how to access UEFI runtime services from within both Windows and Linux. Currently, the only services reliably available are the GetVariable()/SetVariable() services, but this still gives you enough to find most setup settings, as well as the boot order, language settings, etc.

On some Phoenix BIOSes, like on Lenovo G580 UEFI Linux module don't see any UEFI vars. But can create it. :)
