+\r
+  Enables the 64-bit paging mode on the CPU. CR0, CR3, CR4, and the page tables\r
+  must be properly initialized prior to calling this service. This function\r
+  assumes the current execution mode is 32-bit protected mode with flat\r
+  descriptors. This function is only available on IA-32. After the 64-bit\r
+  paging mode is enabled, control is transferred to the function specified by\r
+  EntryPoint using the new stack specified by NewStack and passing in the\r
+  parameters specified by Context1 and Context2. Context1 and Context2 are\r
+  optional and may be 0. The function EntryPoint must never return.\r
+\r
+  @param  Cs          The 16-bit selector to load in the CS before EntryPoint\r
+                      is called. The descriptor in the GDT that this selector\r
+                      references must be setup for long mode.\r
+  @param  EntryPoint  The 64-bit virtual address of the function to call with\r
+                      the new stack after paging is enabled.\r
+  @param  Context1    The 64-bit virtual address of the context to pass into\r
+                      the EntryPoint function as the first parameter after\r
+                      paging is enabled.\r

+                      paging is enabled.\r
