- 2.0 Installation Notes for OS/2
-
- Note: Attempting to execute the mach64 INSTALL program with a Com 4
- device installed, will cause the system to hang. Remove any
- device that uses the base I/O 2E8, before running INSTALL.
-
- 1) Insert disk #1 and run INSTALL from within a full screen DOS session
- (under OS/2) and check the "Power-Up Configuration" to ensure that you
- have selected an appropriate monitor type:
-
- a) OS/2 requires that the 640x480 resolution be configured for the IBM
- default 60Hz vertical refresh rate.
- b) You must configure the card for all resolutions that your monitor
- can support in order to have them functioning correctly under OS/2.
- Only those resolutions that you have configured will display
- correctly.
-
- 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) From the INSTALL Main Menu, select Drivers Installation and pick IBM
- OS/2. Then follow the instructions given on the screen.
-
- Note: If PM Desktop does not reappear after exiting from the full screen
- DOS session, pressing <Enter> will bring you back to full screen.
- If this occurs, you must reboot to get back to the PM Desktop.
-
- 4) When the mach64 driver is installed the SETVGA command will request the
- mach64 drivers diskette to be inserted in to default installation drive.
- SETVGA will not proceed without this diskette. Use the following
- procedure to create the required mach64 diskette:
-
- a) Boot DOS, or enter a full screen DOS session.
- b) Insert a blank disk into drive A: (the bootable floppy drive)
- c) Change directory to the directory created by the installation of
- the mach64 OS2 drivers (default c:\MACH_OS2)
- d) The mach64 disk must have a volume label of MACH64OS2. To create this
- label, at the C:\MACH_OS2 (default) directory type:
- LABEL A:
- You will then see at prompt stating "Volume label (11 characters,
- enter for none)?", please type:
- MACH64OS2
- e) Copy the contents of the MACH_OS2 directory onto the floppy disk.
-
- 5) Run DSPINSTL from within an OS/2 window.
-
- 6) When the Display Driver Install panel appears, select Primary Display
- and click OK to bring up a list of choices. You should see an option for
- ATI mach64.
-
- 7) Select 'ATI Technologies mach64' from the list and click OK. Ignore the
- error message pop-up which says "The installed adapter does not support
- the selected display driver. Do you wish to continue?" and click OK.
-
- 8) When the source directory panel appears, select 'Change' and enter:
- C:\MACH_OS2 (replace c: with your boot drive letter if you don't use c)
- Click 'Set' and then 'Install'. After the files are copied, exit the OS/2
- window or full screen session. Shut down and restart your system.
-
- 9) The PM driver will first come up in 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) Double click on the system menu icon or select close from the system
- menu to close the window.
- g) Shut down and restart your system.
-
-
- 2.1 Uninstalling the OS/2 drivers
-
- 1. Open an OS/2 window or OS/2 Full Screen icon and type:
- DSPINSTL <enter>.
-
- 2. Select Primary Display and click OK to bring up a list of choices. Select
- "Video Graphics Array (VGA) from the list.
-
- 3. When the source directory panel appears, insert the OS/2 /Display Driver
- diskette. Select the drive and path name where the VGA driver resides
- (typically A: or B:), choose Set and then choose Install.
-
- 4. After the install is complete, shut down and restart your system.
-
- Note: After completing step 4, OS/2 is using VGA for a display. If you
- wish to remove the mach64 files from you hard drive continue on.
-
- 5. Restart OS/2 and open a full screen DOS session.
-
- 6. Insert the mach64 disk #1 in the appropriate drive. Change directories
- to the floppy drive and type: INSTALL <enter>.
-
- 7. Select Driver Installation from the Main Menu.
-
- 8. Select IBM OS/2 from the list of applications.
-
- 9 Select UNINSTALL OS/2 Drivers, and follow the instructions on the
- screen.
-
- Note: For OS/2 Special Edition 2.1 for Windows please refer to the
- Known Problem section for uninstall instructions.
-

- ****************************
-
- 3.0 Known Problems
-
- COM 4 CONFLICT
- Attempting to execute the mach64 INSTALL program with a Com 4 device
- installed, will cause the system to hang. Remove any device that uses
- the base I/O 2E8, before running INSTALL.
-
- WINDOWED DOS BOXES
-
- Using the <Alt><Home> function to transform a Windowed DOS box to full
- screen will result in a blank screen. Pressing <Alt><Home> again will
- cause the DOS session to be iconized. It will not return to a Windowed
- DOS box. To access the iconized DOS session, it must be returned to full
- screen mode.
-
- Moving a DOS box of screen may result in garbage lines being generated
- in the DOS Window, when a DOS command is executed.
-
- TASK SWITCHING DOS GRAPHICS
-
- Task switching between DOS graphics and the Presentation Manager,
- will result in the DOS session, becoming distorted.
- The distorted DOS display may appear with a ghosted image of the
- Presentation Manager. The DOS screen may be black or have random trash.
- This problem can be seen with DOS games using VESA modes and other graphics
- based applications.
- Note: Refreshing the DOS session screen will correct the problem.
-
-
- CHESS
-
- The white players are transparent boxes. If you run Chess OS/2 Computer
- vs Computer, the white team chess pieces are not distinguishable, but
- one can see something moving around as a square piece where the chess
- pieces are moving
-
- CHANGING REFRESH RATES
-
- When changing refresh rates of 640x480 resolution using the mach64
- installation diskettes from a DOS full screen window, the computer freezes
- up. This is a design limitation. IBM OS/2 must use 60 Hz VGA frequency
- since it sets the registers directly. This is a limitation of OS/2 and
- only applies to the 640x480 resolution. Other resolutions may be configured
- at any vertical refresh rate.
-
-
- WIN OS/2 SESSIONS
-
- WIN-OS/2 sessions, FULL SCREEN or SEAMLESS may not start and display an
- error message, " PROGRAM MANAGER SYS 3170: A program in this session
- encountered a problem and cannot continue."
- Occasionally when DSPINSTL or a Selective Install is performed the order
- of the lines in the CONFIG.SYS file gets changed.
-
- WHEN the DEVICE=VMACH64.SYS line precedes the VVGA.SYS line in CONFIG.SYS
- the problem will occur. To correct the problem edit the OS/2 CONFIG.SYS
- file and ensure that the DEVICE=C:\OS2\MDOS\VVGA.SYS line comes before
- DEVICE=C:\OS2\MDOS\VMACH64.SYS
-
-
- WIN OS/2 SESSIONS
-
- Attempting to combine multiple WIN-OS/2 windowed sessions with WIN-OS/2
- sessions configured for full screen may cause the system to lock. In the
- interim we would recommend configuring all WIN-OS/2 sessions for either
- windowed or fullscreen mode.
-
-
- VIDEO PLAYBACK
-
- Blank or Garbled video playback, particularly with the UltiMotion clips.
-
- 64K Color modes: UltiMotion clips will come up as mostly blue when
- running 800x600, 65K color or 1024x768, 65K color modes. This is a
- technical problem with the 2.1 release of OS/2 UltiMedia; it is unable
- to use more than 1MB of video memory.
- The current 2.11 release of OS/2 UltiMotion, does not experience this
- problem.
-
- Overlapping a Video playback window with another window may result in
- the video bleeding through the overlapping window.
-
-
- MACH64 DIAGNOSTICS
-
- Due to the nature of mach64 diagnostics, it can not be run under OS/2. The
- diagnostic program modifies hardware settings, which may cause the system
- to lock.
- To run the diagnostics, boot your system for a DOS bootable diskette.
- Insert disk 1 of the mach64 disks and type M64DIAG.
-
-
- Uninstalling ATI Drivers under OS/2 for Windows
-
- 1) Do a Selective Install to reconfigure OS/2 for VGA.
-
- 2) To manually UNINSTALL the drivers...
-
- Remove these lines from the CONFIG.SYS file:
- DEVICE=C:\OS2\ATI0.SYS
- DEVICE=C:\OS2\ATIM64.SYS
- DEVICE=C:\OS2\VAD64.SYS
-
- Remove these files from the OS/2 drive:
- \OS2\ATIO.SYS
- \OS2\ATIM64.SYS
- \VAD64.SYS
- \OS2\DLL\M6432.DLL
- \OS2\INSTALL\M6432.DSC
-
- Remove these files from the Windows directory:
- C:\WINDOWS\SYSTEM\FMACX.DRV
- C:\WINDOWS\SYSTEM\SMACX.DRV
-
- Remove the [Macx] section from the WINDOWS SYSTEM.INI file:
