+  Writes a 64-bit value to a Machine Specific Register(MSR), and returns the\r
+  value.\r
+\r
+  Writes the 64-bit value specified by Value to the MSR specified by Index. The\r
+  64-bit value written to the MSR is returned. No parameter checking is\r
+  performed on Index or Value, and some of these may cause CPU exceptions. The\r
+  caller must either guarantee that Index and Value are valid, or the caller\r
+  must establish proper exception handlers. This function is only available on\r
+  IA-32 and x64.\r
+\r
+  @param  Index The 32-bit MSR index to write.\r
+  @param  Value The 64-bit value to write to the MSR.\r
