+Routine Description:
+  Create a Read to Boot Event.

+  added and now it's possible to not voilate the UEFI specification and use 
+  the ready to boot event class defined in UEFI 2.0. This library supports
+  the R8.5/EFI 1.10 form and R8.6/UEFI 2.0 form and allows common code to 
+  work both ways.

+Abstract:
+
+  Firmware Volume Block Protocol Runtime Abstraction
+
+  mFvbEntry is an array of Handle Fvb pairs. The Fvb Lib Instance matches the 
+  index in the mFvbEntry array. This should be the same sequence as the FVB's
+  were described in the HOB. We have to remember the handle so we can tell if 
+  the protocol has been reinstalled and it needs updateing.
+
+  If you are using any of these lib functions.you must first call FvbInitialize ().

+
+  mFvbEntry is an array of Handle Fvb pairs. The Fvb Lib Instance matches the

+  were described in the HOB. We have to remember the handle so we can tell if 
+  the protocol has been reinstalled and it needs updateing.
+
+  If you are using any of these lib functions.you must first call FvbInitialize ().
