#9 Imagine-128 Display Drivers for OS/2 Warp 3.0
Version 2.11 (I2 Beta version)
------------------------------------------------------------------
03/11/96
==================================================================
Installing the drivers
==================================================================
(1) For starters:
Make sure OS/2 is configured for VGA.
Make sure I128VID, I128WOS2 and I128.DSP reside on a floppy in drive A:
Make sure the LABEL of the floppy is "I128 DRVS" (omit the quotes!).
(2) Open a windowed OS/2 session.
(3) Issue the command A:I128INST A: C:
where A: is the drive holding the installation diskette
and C: is your OS/2 boot partition.
If your installation drive or boot partition is different,
substitute the correct drive letter.
DON'T FORGET THE COLON AFTER THE DRIVE LETTER.
(4) OS/2 Display Install will be started automatically.
Under OS/2 Warp 3.0 Display Install may report that your primary
display is "Video Graphics Array (VGA)." Select "Primary Display"
and press the "Continue" button.
(5) Select the "32-bit #9 Imagine-128 Display Drivers" and complete
the installation. You must scroll to the top of the "Primary Display
Driver List" to find the entry for the I-128 drivers.
(6) Remove the diskette frrom drive A:, shut down, reboot,
and your display will be running at 640x480x256.
==========================================================================
ADJUSTING THE REFRESH RATE OF YOUR DISPLAY
==========================================================================
With release 2.11 of the I-128 OS/2 drivers, refresh-rate selection
in OS/2 PM is controlled from the Number Nine I-128 object, which
is accessible from your SYSTEM SETUP folder. Once you open the
Number Nine I-128 object you can obtain instructions on selecting
refresh rates by pressing the I-128 object's "Help" button.
Refresh rates and resolution selection in full-screen Win-OS/2 are
managed by the I-128 HawkEye utilities.
==========================================================================
USING THE I-128 HIGH-RESOLUTION DRIVERS UNDER OS/2
==========================================================================
(1) Rebooting your computer: If you find you must shut-down OS/2 and reboot
your computer after running in high-resolution mode under OS/2, always
perform a "cold" boot, not a "warm" boot.
A "cold" boot is accomplished by pressing the RESET button on your
computer, or by pressing the OFF button before you attempt to restart.
A "warm" boot is accomplished by pressing Ctrl-Alt-Del. Pressing
Ctrl-Alt-Del while the I-128 is in high-resolution mode may not reset
the graphics engine, and may leave the I-128 in high-resolution mode
at shutdown.
(2) Use Imagine 128 Series 2 Display Driver Disk 2,
the WINOS display driver disk, for full-screen Win-OS/2.
To perform the installation, start a full-screen
Win-OS/2 session and run SETUP from the WINOS display driver disk.
After installation, if you will be running seamless Win-OS/2, we recommend
that you edit your WIN.INI file (in your \WINDOWS or your \OS2\MDOS\WINOS2
directory) and change the entry that looks like this:
load=C:\OS2\MDOS\WINOS2\NUMBER9\HAWKEYE.EXE
to this:
load=
Changing this line prevents HAWKEYE from starting automatically in a
seamless Win-OS/2 session. OS/2 WILL NOT PERMIT HAWKEYE TO RUN IN A
SEAMLESS SESSION. Attempting to start it in seamless Win-OS/2 produces
an error message.
You can start HawkEye in a full-screen Win-OS/2 session by double-clicking
on the #9 HawkEye Control Panel.
Likewise, in the same directory, you should edit your SYSTEM.INI file
as follows:
(a) Look at the top of the file for the [boot] section heading.
Then, in the [boot] section, look for the line:
fdisplay.drv=i128.drv
If you find this line, change it to read:
fdisplay.drv=i128wos2.drv
(b) Look toward the bottom of the file for a section headed
[Imagine-128]. If you find it, look for a line like this:
CFG=D:NUMBER9
If you find such a line (because you have OS/2 on a drive
other than C:), change it this way:
CFG=D:\NUMBER9
We have added a backslash after the colon. If we don't do
this, full-screen Win-OS/2 and Hawkeye will be unable to find
the configuration file.
(3) Running DOS graphics applications in a window: The Imagine-128 drivers
support the running of EGA and VGA graphics-mode DOS applications in a
window on the PM desktop. To employ this feature of the I-128 you must
make sure that your DOS graphics application is set to operate in a
standard EGA or VGA mode. The most advantageous mode supported is
640x480x16 colors.
(4) A word of caution about 16.7-million-color modes: These drivers offer
16.7-million-color modes at resolutions up to 1024x768. We have tested
the drivers at these modes and we believe they operate correctly.
Keep in mind, however, that 16.7-million-color modes are new to OS/2 video
drivers. To date, few application developers have had the opportunity to
test their applications in these modes. You may therefore expect problems
with some applications when run at 16.7 million colors.
We have confirmed problems with Corel Draw version 2.5 for OS/2, and
advise that you do not attempt to run this version of the program in a
16.7-million-color mode.
We have also confirmed that OS/2 Warp's Software Motion Video feature
does not work correctly with these drivers at 16.7-million colors.
Correct operation in 16.7-million-color modes will require updates to
IBM's Software Motion Video subsystem as well as to the I-128 drivers.
We are working with application developers to identify and resolve
problems connected with 16.7-million-color display modes.
