AST RESEARCH, INC.        TECHNICAL BULLETIN # 1757          09/09/97 
 
 
 
TITLE:  BravoMS 6233,6266,6300Win3.11,Syst Hang
 
 
ISSUE 
 
   After the customer installs DOS version 6.22, and Windows For 
   Workgroups version 3.11 (WFW) on a Bravo MS 6233, 6266, or 6300, 
   the system may hang when booting to Windows. When this occurs, 
   the system may display the Windows logo for about thirty seconds, 
   and display an error message on a black screen. For example:
   
      "Error loading mmsound.drv"
   
   This incompatibility issue occurs only under the following three 
   conditions:
   
      1. Installing DOS version 6.22.
      2. Using Ultra Direct Memory Access (UDMA)
         hard disk drives.
      3. Loading into Windows 3.11.
   
   
   This issue applies to the following systems: 503368-101, 
   503368-201, 503370-101, 503370-201, 503502-101, and 503502-201.    

 
BACKGROUND 
 
   No failure occurs with Non-UDMA drives.    

 
ACTION 
 
   To avoid the issue described above, remove from the
   AUTOEXEC.BAT file, the line referencing the SMARTDRV.EXE file. An 
   example of this line may be:
   
      C:\DOS\SMARTDRV.EXE /X    

 
NOTES 
 
   If the customer must use SMARTDRV, the options below will
   work:
   
   1. Load SMARTDRV High. 
   2. Run MEMMAKER (once) prior to starting Windows.
   
   AST is currently investigating this issue and, once the 
   information becomes available, we will update this bulletin.
