Installing the Driver
---------------------
1. Run the INSTALL program for your ATI video adapter (found on your original
ATI diskette #1) under DOS or in a Full Screen DOS session (under OS/2)
and check the "Power-Up Configuration" to ensure that you have selected
an appropriate monitor type. OS/2 requires that the 640x480 resolution be
configured for the IBM default 60Hz vertical refresh rate. Other
resolutions may be configured at any vertical refresh. Note that only
those modes which have been enabled in the power-up configuration will
be available under OS/2.
2. Check The Minimized Window Viewer to see if you have any WIN-OS/2 or
DOS sessions iconized. Close them all as the install may not work
if a WIN-OS/2 session is running.
3. Before proceeding, ensure that you've unpacked the OS2V12.ZIP file into
a directory containing LOADER.EXE and LHARC.EXE, then run the LOADER
program to install the driver files. A README file containing
instructions for this procedure is included in OS2V12.ZIP.
4. Open an OS/2 window or full screen session and type
DSPINSTL
then press the enter key.
5. When the Display Driver Install panel appears, select Primary Display
and click OK to bring up a list of choices. Select the option for
ATI mach8/mach32. If you don't see this option, ensure that the
ATIM32.DSC file is located in your \OS2\INSTALL directory.
6. When the source directory panel appears, change the source directory
to C:\MACH_OS2 (substitute your OS/2 boot drive for C: if appropriate).
Then click the Install button.
7. When the drivers have been installed, a message will appear, indicating
that changes have been made to your configuration. Click OK, EXIT the
OS/2 session, and Shut Down OS/2.
8. When you start OS/2 again, the ATI PM driver will first come up in a
640x480, 256 colors mode. Use the following steps to change the screen
resolutions or number of colors:
a. Open 'OS/2 System' icon.
b. Open 'System Setup' icon.
c. Open 'System' icon.
b. Select the 'Screen' tab.
e. Select the desired resolution and number of colors from the list.
f. Point to the title-bar icon and double click to close the window.
g. Shut down and restart your system.

NOTES and Bug Fixes
===================
. 8514-ULTRA.
-------------
Initialization of the 800x600x256 mode on an 8514-ULTRA requires direct
access to the 8514-ULTRA ROM.
a. On Micro Channel machines, the ROM address for the 8514-ULTRA is fixed
at C680. This physical address is not accessible directly through OS/2.
Since initialization of the 800x600x256 mode requires direct access to
the 8514-ULTRA ROM, this mode is not available on MCA systems.
b. ISA machine users : if you can change the location of the 8514-ULTRA ROM
(using the INSTALL program on ATI disk #1; Set Power Up Configuration),
please set it to one of C800, C900, CA00, CB00,.....,etc. The ROM must
be located at a 4K page boundary (ie at a hex address that ends in "00"),
to be accessible under OS/2. Unless the ROM is accessible, the
800x600x256 mode cannot be initialized.
. Switching from WINOS2 full screen directly to full screen dos, os/2.
----------------------------------------------------------------------
Gives a very dim screen on 64K color modes. This is now fixed.
. PM : Open System setup, menus are too slow
------------------------------------------
This has been speeded up by a factor of two.
===========================================================================
Extra Notes
-------------
. Remember that you must close all WIN-OS/2 sessions or the install will fail.
. RUNNING DOS EGA/VGA APPLICATIONS UNDER OS/2 ON GRAPHICS ULTRA +/PRO
DOS graphics applications that run in any of the EGA or VGA planar modes
listed below can not run in a DOS window session under OS/2. There is no
separate VGA memory on the display adapter to virtualize the VGA graphics
mode drawing in an accelerator drawing mode. Therefore, please use these
programs in a DOS full screen session.
mode 0dh 320x200 16 colors
mode 0eh 640x200 16 colors
mode 0fh 640x350 2 colors
mode 10h 640x350 16 colors
mode 11h 640x480 2 colors
mode 12h 640x480 16 colors
These modes cannot be supported as vga memory is generally not available
when hardware accelerator features are enabled. We can only enable these
features at a big penalty in performance, so they will not be enabled.
. RUNNING THE DISPLAY ADAPTER'S TEST PROGRAM
The display adapter diagnostics program should only be run in a DOS full
screen session. Also, do not attempt to switch to PM desktop or other tasks
in the middle of the diagnostic, otherwise the desktop might be corrupted.
. CORRECTING PROBLEMS AFTER INSTALLATION.
If, after installation, you are unable to start OS/2 2.1, please consult
Page 128 of the OS/2 2.1 supplied Installation Guide :
Resetting Display Adapter to VGA (SETVGA)
Ignore any errors that you may get at the end of the procedure. The
SETVGA.CMD script assumes that an SVGA driver is installed and will complain
if it fails to delete it.
. CHANGING SCREEN RESOLUTIONS IN PM SYSTEM SETUP.
After clicking on the resolution you wish, close the system window by double
clicking on its top left icon. This will write your settings to disk. Your
changes will not take effect until the system window is closed and you reboot
your machine.
. Hanging with DRAM cards
We have had a problem with hanging DRAM cards. This is now fixed, but dram
card users may experience slower performance than vram card owners.
Current known problems and limitations
--------------------------------------
1. DIGITAL VIDEO PLAYER. When playing Ultimotion video clips in 64K color
mode, the picture comes up as mostly blue. Playing Indeo video clips will
hang the system. This is due to improper handling of high and true colour
modes by the OS/2 Digital Video Player. Please switch to 256 color mode to
play these videos and wait for IBM's fix.
2. WP for OS/2, 123 for OS/2. These two programs are confirmed to have
problems running in 64K color mode. Please switch to 256 color mode to use
them and wait for the fix from their respective manufacturers.
3. 640x480 IN 70HZ REFRESH RATE. OS/2 INSTALL and the generic VGA driver
have a problem displaying 640x480 at a 70Hz refresh rate. Change the refresh
rate to the IBM default of 60Hz to install OS/2, as noted in step 1 of
"Installing the Driver". Note that this is a limitation of OS/2, and ONLY
applies to the 640x480 resolution. Other resolutions may be configured at
any vertical refresh rate.
4. WIN-OS/2 CLOCK IN DIGITAL DISPLAY. When the clock is running in digital
mode without a title bar, switching to any full screen task and back will
corrupt the clock display. This bug is still under investigation. A
temporary workaround is to use the clock in analog mode or in digital mode
with a title bar. Refreshing the clock window will also correct the display.
5. WIN-OS/2 CLOCK AND OS/2 DIGITAL VIDEO PLAYER. When playing a video clips
with a seamless WIN-OS/2 CLOCK running at the same time, some artifacts may
show on screen. This bug is still under investigation. Close the seamless
WIN-OS/2 clock before using the digital video player.
6. OS/2 LOCKS ON SHUTDOWN. Periodically OS/2 may lock during shutdown before
displaying the "Shutdown is completed" message. This is a documented problem
with Presentation Manager. The following appears in the OS/2 README file:
o During a system shutdown, there might be
times when the "Shutdown is completed"
message is not displayed. If this happens,
wait until all disk activity is complete,
then power off the system.
7. OS/2 SELECTIVE INSTALL REPORTS THE 8514/A DRIVER INSTALLED. The Selective
Install feature of OS/2 actually searches the hardware in the system, and
detects the 8514/A compatibility of the ATI accelerators. Selective Install
will report the current driver as being "8514/A", even after you've installed
the ATI OS/2 drivers.
8. WRONG DRAWINGS ON OVERLAPPED WINDOWS.
Running multiple seamless windows sessions could cause drawing on
overlapping windows to be wrong. Problem is currently under investigation.
Refreshing the problem window will clear the problem.
9. OUT OF SYNC MONITORS, VGA, AND MACH32. (640x480 MUST BE AT 60Hz)
To run the OS/2 VGA driver for the MACH32 card, you MUST use the ATI
INSTALL program to select a 60Hz (IBM Default) refresh rate for the
640x480 resolution.
If not, the monitor will be out of sync. After the first time you boot
OS/2 in VGA mode, you can reset the refresh rate to any value your
monitor supports, but every time you run DSPINSTL, you must reset the
refresh rate to 60Hz.
