  27. KEYWORDS: OS2INFOAPAR OS2VIDEO                                                  
  28.                                                                                 
  29. 1) Video goes out of synch when switching from DOS full screen                  
  30.    or WINOS/2 full screen to desktop.                                           
  31.    This is usually caused by Tseng ET4000 chips in the video                    
  32.    controller (batch TC6059AF or higher only!).  If the customer                
  33.    has these chips in his video board, send the fix for APAR                    
  34.    PJ03677.                                                                     
  35. 2) SYS3176 error when starting a DOS session.                                   
  36.    Try setting HW_ROM_TO_RAM to ON for each session that is                     
  37.    having the problem.  Also try changing DOS_RMSIZE to 624                     
  38.    instead of 640.  If this does not work, the VSVGA.SYS fix                    
  39.    from IBM might resolve the problem.                                          
  40. 3) ATI 8514 Ultra or Graphics Ultra locks with white screen on                  
  41.    bootup.                                                                      
  42.    The older ATI ROM chips return an incorrect monitor ID when                  
  43.    queried by OS/2.  Have customer call ATI at 416-756-0711 to                  
  44.    obtain an update.  Remember, these boards MUST be set up as                  
  45.    an 8514 PRIMARY display and the statement                                    
  46.          DEVICE= OS2 MDOS VVGA.SYS                                              
  47.    MUST be changed to                                                           
  48.          DEVICE= OS2 MDOS VSVGA.SYS                                             
  49. 4) C0000005 error on bootup.                                                    
  50.    If the customer has Western Digital chips (C30 or C31), with                 
  51.    1MB memory, send the fix for APAR PJ03721.                                   
  52.    If not, remove the SVGA info from the CONFIG.SYS file.  Note                 
  53.    that this will limit the user to VGA only. Change                            
  54.        SET VIO_VGA=DEVICE(BVHVGA, BVHSVGA)                                      
  55.        DEVICE=C: OS2 MDOS VSVGA.SYS                                             
  56.    to                                                                           
  57.        SET VIO_VGA=DEVICE(BVHVGA)                                               
  58.        DEVICE=C: OS2 MDOS VVGA.SYS                                              
  59. 5) Trident video problems:  If the user is experiencing                         
  60. problems with super VGA on Trident based video boards,                          
  61. they will need to call Trident (not IBM) for the proper                         
  62. SVGA driver.  If they have problems with the driver that                        
  63. Trident sends them, they need to call Trident, not IBM.                         
  64. IBM only supports VGA mode on Trident boards with 8900 or                       
  65. 9000 chipsets.  The 8800 chipset is not currently supported                     
  66. nor do I believe that it will be.                                               
  67. 6) Dell computer Video problems.  Dell's 486/50 uses a                          
  68.    Western Digital 90C30 chip.  Our standard BVCHSVGA.DLL                       
  69.    fix should help.  Other models (325SX, 325, NL25, etc.)                      
  70.    do NOT use this chip and this fix DOES NOT apply.                            
  71.    Dell uses a customized Phoenix BIOS.  Here are a few                         
  72.    CMOS settings that have been known to help.  Use                             
  73.    CTRL-ALT-ENTER to access CMOS setup:                                         
  74.    FAST_VIDEO                  OFF if sync problems                             
  75.    FAST_VIDEO_BIOS (shadowing) OFF if problems                                  
  76.    BIOS_CACHING                OFFif problems                                   
  77.    COMPATIBILITY_SPEED         ON for faster Mhz machines                       
  78. 7) Errors loading video drivers on bootup.  The selective                       
  79.    install utility sometimes will add the same device driver                    
  80.    statement more than once to the CONFIG.SYS file.  This will                  
  81.    result in an error message every time the user boots up.                     
  82.    The system will function properly and upon investigation                     
  83.    you will find that driver file DOES exist in the proper                      
  84.    directory.  It is simply trying to load the driver twice                     
  85.    during bootup, the second attempt will fail.  Remove the                     
  86.    duplicate DEVICE= statement from the CONFIG.SYS.                             
  87. LOCAL FIX:                                                                      
  88.                                                                                 
  89.
