Dear OS/2 User,

We know you have all been waiting patiently, and the second beta release
of SciTech Display Doctor for OS/2 is finally here! This version is still
a little rough around the edges for the installation process, as we have
not completed the GUI configuration programs yet. Configuring the drivers
is a little cumbersome and done with command line utilities for the
moment, but we are now working on the dialog driven installation program
and control panel utilities.

Please read the readme.txt file included in the ZIP file archive
thoroughly before attempting to install SDD for OS/2.

For those who are interested we also have the MGL fully ported and
running under OS/2 fullscreen sessions. The first beta release is already
available on our ftp site, and we expect to have the next beta release
ready soon with bug fixes and updates.

Where to find the SDD for OS/2 beta
-----------------------------------

You can download the install ZIP file from SciTech"s ftp site:

ftp://ftp.scitechsoft.com/sdd/beta/os2/sddos2_10_b2.zip

and

ftp://ftp.scitechsoft.com/sdd/beta/os2/ibmgradd.zip

The ibmgradd.zip file contains all the IBM 0.77 GRADD files needed by the
installation. You will only need to download and unzip this archive once
for all beta releases (make sure you unzip with -d!).


Supported Hardware
------------------

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.

Please note that we are in the process of moving all our existing device
support code to our new SciTech Nucleus device driver architecture. If
you have a chipset that is not listed below that you would like to see
supported in SciTech Display Doctor for OS/2, please send an email to
sddos2@scitechsoft.com to let us know.

We want your feedback!!
-----------------------

Your feedback is important to us, to ensure that we are building a
product that works the way you want it to. We need feedback from our beta
testers, both positive and negative. All feedback for the beta program
should be directed to sddos2@scitechsoft.com for the time being (we will
soon have a HTML bug reporting page in place).
