================================================================== #9 Imagine-128 Display Drivers for OS/2 versions 2.11 and Warp 3.0 for Windows Version 1.08 - BETA RELEASE ------------------------------------------------------------------ 03/1/95 Please give us any feedback using the file FEEDBACK.TXT. Thank you. ================================================================== ================================================================== 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 2.11 Display Install will report that your primary display is "Super Video Graphics Array (Cirrus Logic)." Under OS/2 Warp 3.0 Display Install may report that your primary display is "Video Graphics Array (VGA)." In either case, select "Primary Display" and press the "Continue" button. Note: Under OS/2 Warp 3.0 Display Install may warn you that your primary display does not support high resolution modes. IGNORE THE WARNING AND SELECT "Continue". (5) Select the "32-bit #9 Imagine-128 Display Driver 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. (7) Select the resolution you want from the SYSTEM object. Once more, shut down and reboot. ========================================================================== 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 does not reset the graphics engine, and OS/2 leaves the I-128 in high-resolution mode at shutdown. (2) Using the #9 HawkEye drivers for full-screen Win-OS/2: You can install version 2.12 or later of the #9 HawkEye Windows 3.1 software for use in full-screen Win-OS/2. To perform the installation, start a full-screen Win-OS/2 session and follow the instructions for installing the drivers under Windows 3.1. 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) Adjusting the refresh rate of your monitor: By default the refresh rate of your display is set to 60Hz at installation. To adjust the refresh rate, start a full-screen Win-OS2 session, select the same resolution as your wish to use for you PM desktop, and set the refresh rate as you prefer. The monitor settings you choose will immediately take effect on your PM desktop. (4) 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. (5) 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. (6) Please be sure to use only the "Default" cursor set included with Warp for Windows. Use of any of the other sets will result in corruption, and cursor wrapping.
