+; [TAG]  		EIP172120
+; [Category]  	Bug Fix
+; [Severity]  	Important
+; [Symptom]  	 Redirection After BIOS POST feature is not working.
+; [RootCause]  	The flag Indicating whether redirection can happen or not
+; is not updated.
+; 1)The way of Defining signatures and Comparing Signatures are
+; different.
+; 2)The variables defined in CSM16 files( SreDirBin_Base_Segadd,
+; SreDirBin_Base_Offadd, Flag ) are accessed wrongly.
+; 
+; [Solution]  	a) The pointer used to check for signatures must be
+; UINT32* or we should define signatures byte by byte (db
+; '$','S','B','F', db '$','S','B','C'). so changed the way of defining
+; Signatures in CSM16 files from dd '$SBF' to db '$','S','B','F'.
+; b) Variables should be accessed using OFFSET Keyword.

+; [TAG]  		EIP122394
+; [Category]  	Bug Fix
+; [Severity]  	Normal
+; [Symptom]  	0xE0000~0xEFFFF was overwrite by Legacy Serial Redirection
+; module.
+; [RootCause]  	LegacySerialRedirection driver assumed that
+; SerialBootcall.asm will be the first entry in CsmOem16Functions which
+; was wrong.
+; [Solution]  	Added a Signature check code for SerialBootCall.asm and
+; SredirBootFail.asm before it writes to the memory location
+; 0xE0000~0xEFFFF.
