26:  "8042 timeout"

     Explanation:  On most IBM AT-compatible computers, DOS/16M must use
     the 8042 keyboard processor to enable access to extended memory.  This
     message means that a command was sent to the 8042 to enable or disable
     access, but the 8042 has not acknowledged the command.  Most likely, you
     are running on a non-AT-compatible machine.
