Kelvin Video64
Supplemental OS/2 Warp Driver Release
---------------------------------------
The file you have downloaded, KVID-OS2.EXE, contains OS/2 Warp
drivers v1.24 for the Kelvin Video64 board. This is a
supplemental driver release, not a complete driver disk set.
This does not replace your existing Kelvin Video64 driver disk
set, but is a supplement to it. This readme file contains
instructions for installing the drivers. You have already
completed the first step, by unpacking the KVID-OS2.EXE file and
reading this. These drivers are only appropriate for the Kelvin
Video64 board, not other Kelvin models. Do not use these drivers
with the Kelvin MPEG, Kelvin64, or KelvinEZ boards.
When you unpack KVID-OS2.EXE you should have the following files:
ALSC DSC 661 05-30-95 5:32p
SETUP CMD 2,496 01-31-95 9:09a
ALSCA DSP 16,571 07-07-95 6:10p
WINALSC 427,132 07-06-95 12:35p
ALSCPM DL_ 413,420 07-07-95 10:40a
PROMTN CPL 126,272 07-10-95 5:48p

Installing the Drivers
----------------------
These instructions assume that you already have the Kelvin
Video64 board installed in your system, and that you already have
the OS/2 Warp operating system installed on your hard disk. In
addition, these instructions assume you have installed OS/2 on
the "C:" drive and you are installing the Kelvin Video64 driver
from floppy drive "A". We will be using the OS/2 utility
DSPINSTL.EXE utility to install these new drivers. The procedure
is menu driven, and somewhat self explanatory. Here are the
step-by-step instructions for the procedure.
1. Reset your display adapter support in OS/2 to VGA. Refer to
your OS/2 Installation Manual for assistance. This is most
important if you have installed other high resolutions
drivers prior to installing your Kelvin Video64 board.
2. Insert a blank, formatted high density floppy disk into your
"A:" drive, and create a subdirectory on it called OS2. Copy
the Kelvin Video64 files (listed above) into the OS2
subdirectory on the floppy. This is a very important step.
The installer program expects to find the drivers in a
subdirectory called OS2, and won't proceed properly if they
are not. Here are specific commands you can run from a DOS
or OS/2 command prompt:
A: <CR> (logon to the A drive)
MD OS2 (make a directory called OS2)
CD OS2 (change to the new OS2 subdirectory)
C:\{dirname}\KVID-OS2 (unpack files to this subdirectory)
(Substitute the appropriate drive letter and directory name for
your system, where your copy of KVID-OS2.EXE is located.)
3. After creating the floppy driver disk, go to the OS/2
desktop. Before beginning new driver installation, we
recommend that you shut down any other programs you may be
running.
4. From the OS/2 Workplace Shell, double click on the OS/2
System icon.
5. Double click on the Command Prompts folder.
6. Double click on the OS/2 Full Screen or OS/2 Windows icon.
7. Insert the OS/2 driver diskette you created in step 2 into
drive A, and from the command prompt, copy the ALSC.DSC file
from the floppy to the C:\OS2\INSTALL directory. Here is the
command:
COPY A:\OS2\ALSC.DSC C:\OS2\INSTALL
8. From the command prompt, change to the C:\OS2\INSTALL
directory and run DSPINSTL.EXE.
9. Select Primary Display and click the "OK" button on the
Display Driver Install screen.
10. Select the "Alliance Semiconductor ProMotion" display driver
from the Primary Display Driver List screen, and click on the
"OK" button. (You'll probably have to scroll all the way up
to the top of the display driver list to find the Alliance
entry.) At this point, some versions of OS/2 display a
warning about support for display adapters.
11. Use the "Change" button to change the path for the source
files to A:\OS2, and click on the "Install..." button.
12. The Kelvin Video64 drivers are now installed on your
computer. You will be asked to restart OS/2. Click on the
"OK" button.
13. Close the OS/2 command prompt screen with the "EXIT" command.
Close the "Command Prompts Icon View" screen (if it's open).
Remove the OS/2 driver diskette from drive A: and shutdown
OS/2.
14. After the system has restarted, the "OS/2 System folder -
Icon View" should still be open from the previous session.
If it isn't, open it now. Double click on the "System Setup"
icon, then double click on the "System" icon.
15. The "Screen" tab information should be showing by default.
If it isn't, click on that tab to display it. Select the
desired screen resolution, color depth, and refresh rate from
the list and close the applet.
16. Shutdown OS/2 and restart the system for the new setting to
take effect.
Known Issues
------------
a. When running WIN-OS/2 refresh rates for all resolutions
default to 60Hz.
b. At 800x600x16M colors there is no cursor in the System
Editor.
c. With 2MB boards, 800x600x16m @ 72Hz mode fails with wavy
lines through the OS/2 desktop.
d. With 1MB boards, 800x600x256 @ 72Hz mode shows static lines
when moving around the desktop. Problem does not occur with
2MB RAM installed on the board.
OS/2 Limitations
----------------
a. When you play an AVI movie in OS/2 then switch to WIN-OS2
Full Screen, the AVI movie is still displayed.
b. Playing an AVI clip at 16 million colors will not work.
