                   *** AST RAMCLEAR.COM Rev 4.0 FAILURE ***


         IBM  PC's XTs or Compatibles with memory that is not  cleared
         during  Power  On Self Test,  such as above 544K on a PC1  or       
         memory  above Video RAM (C0000-EFFFF),  must  be  initialized
         before the  memory can be used.  AST supplies RAMCLEAR.COM to
         accomplish this.
         RAMCLEAR on the AST Rev 4.0 diskette has an eror in  it.   It
         fails to clear memory from C0000 thru C000F.  When subsequent
         programs  are  run that utilize this area they may fail  with
         "PARITY CHECK 2".

         This  problem  is corrected with RAMCLEAR.COM on Version  4.1
         and above diskettes.
