       This error occurs intermittently on systems that include the
       Sanyo 16x CD-ROM with firmware revision 2.08, AST part number
       234701-910.

       This issue occurs on all systems which include the Sanyo 16x

       To resolve the issue, flash the Sanyo 16x CD-ROM firmware to
       revision 2.09, by performing the following steps:

       1. Obtain file SANYO209.EXE from one of AST's On-Line!
          services as follow:

          AST WWW Site:  http://www.ast.com

          To decompress this file, create a temporary directory
          on your hard drive, copy the downloaded file to that
          directory, and run the file.

       2. Insert a 3.5" formatted 1.44MB diskette into drive A:
          and run the EXTRACT utility. This will transfer the
          diskette image file to the floppy diskette.
