        OS/2 2.1, Avance Logic, Inc. SVGA Drivers 1.41
        ==============================================

        DT: 3-15-1994
        =============

        FOR: IBM OS/2 ver 2.1 and "OS/2 for Windows" 
        ============================================

        
        The driver set consists of the following disk:

        - Display Driver Diskette 1 (volume label DISP 1)
        - Display Driver Diskette 2 (volume label DISP 2)

        
        INSTALLATION:
        -------------
                                                         
        The OS/2 installation procedure is as follows:

        1- Under OS/2 desktop select icon: OS/2 System and then
           icon: Command Prompts.

        2- Select OS/2 or DOS Window (either Desktop or FullScreen).
           
        3- Insert the driver diskette 1 into the floppy drive. (e.g. drive A:)

        4- Run INSTALL.BAT or INSTALL.CMD.  (e.g. if the floppy drive
           is A: and OS/2 is installed on C: then type "A:\install a c")
           For help on INSTALL.BAT, just type "A:\install".
           This will load necessary files needed for OS/2 installation on 
           the hard disk.


           Steps 1-4 are required only for the first time installation of
           Avance Logic drivers. On subsequent installation of drivers
           you may skip the steps 1-4.

        5- On OS/2 window (under Command Prompt) run DSPINSTL.

        6- Select "Primary Display" and click on "OK".

        7- Select "Avance Logic, Inc." in the driver selection menu.

        8- Select "Install Using Defaults for Monitor Type" in the
           menu "Monitor Configuration/Selection Utility".

        9- User will be prompted for Video Refresh Rate Selection Menu.  If
           you are not sure about the monitor, select "NO".  Selecting
           wrong refresh rate not supported by monitor could hang OS/2
           system and you may be required to load the OS/2 system all 
           over again.  If you select "YES", utility: AScanOS2 is invoked
           which will present the available scan rates.  If you are still
           not sure about which scan rates to choose, select the lowest
           scan rates in each of the four columns.  For information on
           AScanOS2 read Help provided in the program.

       10- Select desired display resolution.

       11- Use Disks: Display Driver Diskettes 1 and 2 when prompted.



        NOTE:
        -----

        - Please note the volume label of "Display Driver Diskettes" are
          "DISP 1" and "DISP 2", respectively.  If you make copies of these 
          disks, make sure you give correct volume labels.  (Use 
          DOS command "LABEL" to change the volume label of a disk.)

        - Close all Windows Seamless and FullScreen applications before
          you use DSPINSTL.

        - To change resolution of the installed drivers or to change 
          the refresh rate of the video screen, it is necessary to
          perform the installation steps 5-11 as stated above.
        
        - If you are installing Avance Logic's GUIEngine/ALG2101 board, it is
          possible that during installation the display becomes monochrome.
          This problem will only occur because of incorrect installation
          of the drivers.  The remedy is to shutdown the system and perform
          all the installation steps as stated above. 

        - Under OS/2 desktop, if you are running Windows Seamless session
          it is possible that the shades of colors may change in the 
          OS/2 desktop.  This may happen because of palette change and it
          is quite O.K.  To refresh the screen click mouse on OS/2 desktop
          with Button 2 (just like you do the system shutdown) and choose
          menu item "Refresh Now".  This will refresh the OS/2 desktop
          with correct color shades.  However, this will not correct any
          palette problem for applications running under Windows Seamless.

        - While installing Avance Logic, Inc. SVGA drivers, you may get
          a message saying "...target file SETM.EXE is newer than the
          source file...Select O.K. to overwrite...".  On this message 
          select "OK".



        
        
        DE-INSTALLING DISPLAY DRIVERS:
        ------------------------------

        - It is important to note that you must de-install Avance Logic, Inc.
          drivers and load SVGA (Super VGA) drivers before you change the
          video board on the system.  To change to SVGA drivers follow the
          following steps.

        - If you want to remove Avance Logic, Inc. display drivers, 
          follow steps 5-11 and select "Super VGA (SVGA)" instead of
          "Avance Logic, Inc." when prompted at step 7.  Use IBM's OS/2 
          original disks during this installation.  During this
          installation you may get a message saying "... File BVHSVGA
          is newer than source file ...".  Press O.K. to this dialogue 
          box.  It is not necessary to perform shutdown at this point. 
          
          Open either DOS or OS/2 window.  Insert Avance Logic's driver 
          diskette 1 in the floppy drive and run "DEINSTAL".  For instance, 
          if OS/2 has been installed on drive C then type: "A:\deinstal c".  
          This will restore the original files changed during installation 
          of Avance Logic drivers.  For help on "DEINSTAL" just type
          "A:\deinstal".

          Perform system shutdown now, for the changes to take effect.

          Please note that if your copy of OS/2 is on CD-ROM, make copies
          of "Display Driver Diskettes" from CD-ROM to floppy disks before 
          you perform the de-installation steps as you need the said disks.
          Check OS/2 user manual for instructions as to how to make copies
          of OS/2 diskettes from CD-ROM to floppy disks.





        PENDING ISSUES: 
        ---------------

        The following issues have been found in IBM OS/2 2.1:
        
        - On screen resolution of 1024x768x256colors, under Windows session
          if you open "Color" ("Control Panel") you may not get
          correct "Custom Color Selector".  This has been observed in
          video boards by other manufacturers.  

        - A GPF error occurs when running Windows Benchmark program, 
          "WINTACH", under Windows Seamless session.  This had also been
          observed in video boards by other manufacturers.

        - If "Advanced Tests" are performed on Windows Benchmark program,
          "WINBENCH ver 3.11", running under Windows Seamless session then
          sometimes portion of screen under dialogue boxes and pull-down
          menus gets blank-out.  This error has also been observed in 
          other video boards and does not occur in Windows FullScreen session
          of OS/2.

        We are currently contacting IBM regarding these issues.
