               SciTech Display Doctor 7.0 for OS/2
                       PREVIEW RELEASE 9
               -----------------------------------


Where do you get it?
--------------------

You can download SciTech Display Doctor 7.0 for OS/2 BETA 9 from our 
ftp site using the following URL:

What is SciTech Display Doctor for OS/2?
----------------------------------------

SciTech Display Doctor for OS/2 brings SciTech's proven DOS and 
Windows device support technologies to the OS/2 Operating System. 
Although one of the core features of our DOS and Windows products is 
the support for the VESA VBE/Core standard, the OS/2 version has 
nothing at all to do with VESA services. Rather SciTech Display 
Doctor for OS/2 incorporates the new SciTech Nucleus, Graphics 
Architecture device driver technology to bring SciTech's device 
support to the OS/2 platform.  

SciTech Nucleus is a binary portable, OS neutral, device driver 
architecture. As binary portable drivers, SciTech can fully develop 
and test the core device drivers in the DOS and Windows environments, 
while being able to target any Intel x86 based OS as the runtime 
environment (such as OS/2). This essentially allows the OS/2 product 
to utilise the same SciTech binary device drivers as the DOS and 
Windows versions of the product, improving the quality and 
performance of the drivers for all supported operating systems.  


Runtime Requirements
--------------------

SciTech Display Doctor for OS/2 requires a version of OS/2 Warp 3 or 
OS/2 Warp 4 in order to run. More imporantly, it requires at least 
Warp 3 with fixpack 35, or Warp 4 with fixpack 5 installed. If you 
have a version with earlier fixpacks installed, SciTech Display 
Doctor will refuse to install.  


List of all supported chips:
----------------------------

This is a complete list of the various graphics cards that this 
version of SciTech Display Doctor supports. Please note that this 
list refers to the actual chips being used, not a board-level 
implementation. Thus you will not see any products from Hercules or 
STB on the list, but their products are supported because they use 
S3, Cirrus, Tseng, etc. chips. Also, any card with less than 512KB of 
memory cannot be supported by SciTech Display Doctor.

Note that there are many more chipsets that will work with our 
existing legacy VBE/AF based drivers, that are not included in this 
list. For a complete list of all chipsets supported in our prior 
Windows and DOS products, please visit our web site. We are currently 
in the process of moving all our existing device support code to our 
new SciTech Nucleus device driver architecture. The above list only 
lists those drivers that have been converted, and we won't be 
supporting any chipsets not on the list until those drivers are 
properly converted.  


Changes in BETA 9:
------------------

. Added uninstall icon back into the Workplace Shell icon list.  

. Fixed bugs in hardware line drawing and re-enabled line drawing for 
all drivers. Checked to ensure that JMark line drawing tests work 
properly.  

. Fixed bitmap corruption problems and crashes in Netscape when 
running in 24bit display modes.  

. Fixed problems causing SDD/2 to crash on SMP systems. You should 
now be able to run SDD/2 on SMP versions of OS/2 without a problem 
(although the write combining support needs some work).  

. Fixed crash problem with S3 boards when exiting from fullscreen DOS 
or WinOS/2 sessions. Also fixed problems when starting WinOS/2 
sessions on S3 Trio64 based boards, or switching to and from 
fullscreen DOS sessions.  

. Fixed problems with S3 Trio based boards displaying garbage bitmaps 
and icons on the desktop. Also appears to have fixed the bogus black 
lines in the cursor image that you see occasionally.  

. Fixed bugs in S3 Trio and S3 Vision line drawing, cause bogus lines 
to draw on the screen in various places.  

. Major re-write of display memory FIFO handling for S3 
Trio32/64/64V+ family of boards. This eliminated the display 
distortion on these boards, and they should all now be working 
properly. You can also get much higher refresh rates with these 
boards than you could before.  

. Fixed acceleration code for S3 Trio32 and Trio64 boards, causing 
only the first meg of memory to be available in low resolution 
display mode. All display modes should flip correctly with GACtrl 
now.  

. Fixed problem with black screen and black icons for Rage IIC and 
earlier ATI chipsets. Also fixed problems related to the hardware 
cursor not being able to correctly move off the top of the screen.  

. Fixed cursor glitches for ATI Rage family of chipsets, causing the 
cursor to temporarily go black when the mouse cursor image changes.
