+  <b>PchReset Runtime  DXE Driver Entry Point</b>\n
+  - <b>Introduction</b>\n
+    The PchReset Runtime DXE driver provide a standard way for other modules to 
+    use the PCH Reset Interface in DXE/SMM/Runtime environments. It has no longer
+    hooked ResetSystem() function of the runtime service table.
+
+  - @pre
+    - If there is any driver which needs to run the callback function right before 
+    issuing the reset, PCH Reset Callback Protocol will need to be installed 
+    before PCH Reset Runtime DXE driver. If PchReset Runtime DXE driver is run 
+    before Status Code Runtime Protocol is installed and there is the need 
+    to use Status code in the driver, it will be necessary to add EFI_STATUS_CODE_RUNTIME_PROTOCOL_GUID 
+    to the dependency file.
+    - @link _PCH_RESET_CALLBACK_PROTOCOL  PCH_RESET_CALLBACK_PROTOCOL @endlink
