+// EIP-135253 Updating file name proper in #include
+//
+// 6 10/18/12 5:31a Arunsb
+// Updated for 2.16.1235 QA submission
+//
+// 6 10/10/12 12:23p Arunsb
+// Synched the source for v2.16.1232 backup with Aptio

+// 5 11/04/11 4:37a Arunsb
+// [TAG] EIP67615
+// [Category] Bug Fix
+// [Severity] Normal
+// [Symptom] Keyattribute support doesn't work in AMITSE Keymon support
+// [RootCause] {SETUP_ENTRY_LEGACY_CODE,0} - This initilization code
+// initilize only ScanCode and ShiftKey.
+// It doesn't initilize the AltKey, CtrlKey etc ( Other fields in the
+// KEY_ATTRIBUTE structure).
+// [Solution] Modified the initilization like
+// {SETUP_ENTRY_LEGACY_CODE,{0,0,0,0}}
+// [Files] keymon.c
+//
