Release Notes for DirectX 5.2
-----------------------------
1) DirectX 5.2 includes fixes and changes since the DirectX 5 SDK release. 
   The list of fixes and changes include:

   - DirectX will now install on international language versions of Windows 95.
       Previously, setup was not able to install drivers onto non-supported 
       language versions of Windows 95. Also, setup did not install correct 
       drivers if the regional setting was not the default setting.
   - Digital joysticks can now be used on NEC PC-98 computers.
       On some NEC PC-98 computers, the digital joystick did not work.
   - Certian sound drivers can now be updated.
       Setup did not update older drivers that are not DirectSound supported.
   - DirectX now can be successfully installed onto Chinese (Traditional) 
     version of Windows 95.
       On some machines, after installing DirectX 5 onto Chinese (Traditional) 
       Windows 95, it caused a GPF during boot.
   o New Dxbug.exe and Dxinfo.exe. are now included.
       These reporting tools now report incorrectly placed DirectX components.

2) New language drivers are added. Finnish, Danish and Hungarian drivers can 
   be redistributed in addition to existing redistributable drivers.

3) DirectPlay 5.0a includes redistributable files in the \DPLAY50A directory. 
   Please read the dplay50a.txt in this directory for information about the 
   changes and redistribution.

4) DirectX Media SDK version 5.1 is included in this CD-ROM. DirectX Media
   provides high level animation, 3D graphics and video playback services for
   your application. To install DirectX Media SDK, please run setup from
   \DXMEDIA\X86.

5) There is no longer Internet Explorer 3.02 and ActiveMovie setup from SDK
   setup. However, Internet Explorer version 4.01 is included. You can
   install Internet Explore from \EXTRAS\MSIE401\USA (English version) or
   \EXTRAS\MSIE401\JPN (Japanese version). To install Internet Explorer, double
   click the 'ie4setup' icon from one of these directories.
   ActiveMovie has been renamed to DirectShow and is a part of the Internet 
   Explorer installation. If you want to develop an application that uses 
   DirectShow, please install DirectX Media SDK.


Release Notes
-------------
1) The EXTRAS directory on the CD that contains some goodies you might like.
  
2) This SDK will install on Windows NT version 4.0 and higher for x86
   processors.  However, it will not install any DirectX runtime components
   on NT, since DirectX is built in to NT.  Windows NT 4.0 contains DirectX 2
   compatible 2 versions of DirectDraw, DirectSound, and DirectPlay. A 
   DirectX 3-compatible version, including Direct3D, is available in
   Windows NT 4.0 SP3.

   Be advised that many of the sample applications will not run on NT until
   the components they require (mainly D3D) have been installed through a
   service pack.  Please be patient with us!

3) If you use the Watcom compiler, please get the latest version - it
   contains the latest Windows header files that you will need to compile
   DirectX samples. These files are not included with the DirectX SDK.
   Support for Watcom compilers is available on the web at www.sybase.com.

4) You should know that Direct3D and DirectSound3D were designed to run on
   Pentium-class processors.  Both use floating point math, and are
   therefore quite slow on machines which do not have math co-processors.
   If you use these components, make sure you try your application on a
   486 (especially a 486SX) to verify that it runs adequately.  If it doesn't,
   we recommend that you detect the processor at setup time and refuse to
   run on those machines.

5) Users of the ATI-TV tuner option will experience loss of TV tuner and
   MPEG viewing functionality after installing DirectX drivers.  If this
   happens, the user should uninstall the DirectX drivers by going to the
   control panel, selecting Add/Remove Programs, then selecting DirectX
   drivers and pressing the "Restore Display Drivers" button.

6) The DirectX setup program may be unable to restore ATI OEM drivers for Rage
   1 & 2 using the uninstall option. If this happens, the user may reinstall
   the original OEM drivers using the following steps: in the control panel,
   select "Display" to bring up the "Display Properties" window. Click on the
   "Settings" tab, and select the "Change Display Type" button setting tab.
   Now click on the Adapter Type "Change" button, and select the original OEM
   driver to be reinstalled.

7) Users of the NEC PC-9821Ct20 may experience loss of video adapter 
   functionality if the "no" option is selected rather than the "yes" option at 
   display driver installation dialog box during DirectX5 setup. If "no" is 
   selected, the user might see a screen when the system reboots saying, "The 
   display adapter is disabled.  Press 'OK' to start Device Manager and resolve 
   the problem". The user must then re-enable the display driver by selecting 
   'Display Driver' from the device manager list and selecting the box that says, 
   "Use this device in all hardware profiles". Then select "OK" from device 
   manager.  Next,  press the "Yes" button to restart the computer.  The display 
   driver should now be functional.

8) Users of the NEC PC-9821Cu13/Cu16/Ct20 may experience loss of the 98TV tuner
   functionality after they installing DirectX 5 display driver. If this happens,
   please update your 98TV software. To get those updated software,
   please consult the guide book "CanBe WO TSUKAI KONASOU"-"Software SAISHIN
   NO OSHIRASE(The latest software information)". This page contains descriptions
   about the NEC user support information.
