OS/2 2.0 XR06100 SERVICE PAK README ___________________________________ This README contains helpful hints found in our testing of OS/2 2.0 Service Pak XR06100. It is divided into the following categories: o General System Considerations o WIN-OS/2 Application Compatibility o DOS Application Compatibility o OS/2 Application Compatibility o Workplace Shell o Networks o Display Adapters o Printers o Scanners o Trademarks GENERAL SYSTEM CONSIDERATIONS o XR06100 uses a system proportional font that is designed to meet the International Standards Organization (ISO) 9241 standard and the German DIN 66234 standard on suitable hardware. ISO compliant fonts cause some text strings to be truncated (cut off). If you do not want to use ISO compliant fonts, modify the OS2.INI file to install fonts that are not ISO compliant. Font changes made in the OS2.INI file are global and affect all applications. If you have REXX installed and you want to modify the OS2.INI file, you can type the following information into a CMD file and use it to change the font. /* */ call RxFuncAdd "SysIni", "RexxUtil", "SysIni" AppName = "PM_SystemFonts" KeyName = "DefaultFont" FontName = "10.System Proportional Non-ISO" call SysIni "USER", AppName, KeyName, FontName||"0"x exit After the file has been run, shut down and restart the system. o If you experience video corruption: - Display the pop-up menu for the desktop; then select Refresh to redraw the desktop. - If the screen goes blank, press Alt+Esc to switch among the applications to force repainting of the screen. o DOS image files on the hard disk (virtual machine boots - VMBs) need to use the FSFILTER and FSACCESS drivers provided with this version of OS/2 after XR06100 is installed. FSFILTER and FSACCESS drivers are located in the \OS2\MDOS directory. If the new versions of these files are not used, a SYS 3176 message may appear. o If you are installing XR06100 from a CD-ROM, please note that the CD-ROM support of the operating system will be limited to the support provided prior to installing XR06100. o The Check disk choice for a CD-ROM object will not display information about the CD-ROM. To obtain information about the CD-ROM: 1. Point to the CD-ROM drive object. 2. Click mouse button 2. 3. Select the arrow to the right of Open. 4. Select Settings. 5. Select the Details tab in the notebook. o While PC Manufacturer System testing continues, current compatibility information about tested systems is available through your dealer, Marketing Representative, CompuServe**, IBM National Support Center Bulletin Board System (NSC BBS), and IBMLink. o If your system was originally a DOS system and you installed OS/2 2.0 (XR02000 or XR06000), you might experience a SYS1730 error message after the installation of XR06100. The SYS1730 error message will pop up during start up of the system and will read: "Codepage combination 437,850 is not acceptable for the keyboard, DEVINFO command". To correct this problem, add the following line at the end of your CONFIG.SYS: DEVINFO=KDB,US,C:\US\OS2\KEYBOARD.DCP WIN-OS/2 APPLICATION COMPATIBILITY APPLICATION NOTES: After Dark ---------- When the Demo mode is invoked, the DOS (VDM) session might not run. If you select the automatic update of AUTOEXEC.BAT, you must comment out the AD-DOS.COM statement or you will experience video synchronization problems. AmiPro** 2.0 and 3.0 -------------------- Equation symbols might be incorrect after certain printer drivers are installed. The following printer drivers are installed: - Canon** BubbleJet - HP DeskJet** - HP LaserJet II - HP LaserJet III - HP Plotter Borland Turbo and Pascal debugger --------------------------------- Run in a full-screen session. CorelDRAW** 2.0 --------------- Install from a DOS or OS/2 session. CorelDRAW 2.5 ------------- At the end of a CorelDRAW Version 2.5 installation, you might experience problems after selecting one of the View README options. The View README options are "Yes" and "No". If you select "Yes", CorelDRAW will not run. However, objects will be generated. You must restart your system and re-create each object, using the Migrate Applications program. If you select "No", CorelDRAW will not run. A folder will appear, but the objects will be missing. You must restart your system and create each object, using the Migrate Applications program. Drafix CAD Version 1.11 ----------------------- Run the program in a WIN-OS/2 full-screen session. Drafix CAD Version 2.0 ---------------------- Run the program in a WIN-OS/2 full-screen session. Drafix CAD Version 3.0 ---------------------- Run the program in a WIN-OS/2 full-screen session. FrameMaker** ------------ Use a mouse to select table cells. Freelance Graphics** -------------------- o If you are using Freelance in a WIN-OS/2 window, you might get incorrect background color when viewing a thumbnail of a template. This will not affect the performance of the application. o If you are using an IBM 4029 PostScript printer, you will need to remove the old printer driver and replace it with the updated driver. In order to do this, you must do the following: 1. Close all your Windows applications. 2. Open the WIN-OS/2 full-screen session. 3. Open the Control Panel (from WIN-OS/2 MAIN). 4. Open Printers. 5. Highlight the IBM 4029 Postscript printer. 6. Click on Configure. 7. Click on Remove. 8. Click on Yes to confirm that you want to remove the printer driver. 9. Click on Add Printer. 10. Scroll to the IBM 4029 section. The new printer names are: IBM 4029 (17 Fonts 300DPI) IBM 4029 (17 Fonts 600DPI) IBM 4029 (39 Fonts 300DPI) IBM 4029 (39 Fonts 600DPI). 11. Highlight the appropriate printer and click on Add. 12. Click on Current when you get a message that the driver is already on the system. 13. After the printer driver installation is complete, you will have to reconfigure the printer settings such as select the port, make sure the default settings are correct, and set the printer as your default printer. 14. When you have configured the printer, click on OK to close the Printer Control Panel. You should now be able to print from Freelance Graphics to your IBM 4029 PostScript printer. Guide** for Windows ----------------- Run the program in a WIN-OS/2 full-screen session. Microsoft** Windows** Printing System -------------------------------------- The OS/2 spooler must be disabled. To disable the spooler: 1. Open OS/2 System. 2. Open System Setup. 3. Open Spooler. 4. Point to the title-bar icon. 5. Click mouse button 2. 6. Select Disable Spooler. (If the Enable spooler choice is indicated, it means that the spooler is already disabled.) 7. Restart your system. If you are using a parallel printer connected to your system, direct the output of the printer to LPT1 instead of LPT1.OS2. WARNING: If you disable the OS/2 spooler, you will not be able to do background printing. You should print only from one application at a time; otherwise, the data will be intermixed on the printer. Microsoft Mail for Windows -------------------------- Run MsMail for Windows in a Win-OS/2 full-screen session. The security feature does not work properly when the application runs seamless. PhotoFinish** 2.0 ----------------- This application might generate a General Protection (GP) Fault. This means that the program cannot continue to run. An error message will appear and the application will close. You must restart the application. Powerpoint** 3.0 ----------------- If you are running a WIN-OS/2 window session, you might get incorrect background color when viewing a thumbnail of a template. This will not affect the performance of the application. WINGZ** for Windows ------------------- If you are using this application, you must install ATM fonts. WordPerfect** for Windows ------------------------- o If you cannot run WordPerfect for Windows, you can contact WordPerfect Corporation for their updated version. Or, you can change to the directory that contains WPWINFIL.EXE and run FIXWP WPWINFIL.EXE. (To enable WordPerfect for Windows to run again under DOS and Windows 3.0, run UNFIXWP WPWINFIL.EXE.) o Button Bar icons do not always appear correctly. Button Bar text and processing are correct. DOS APPLICATION COMPATIBILITY o Do not use the DOS system utility programs for file or directory management when running applications in a native DOS environment. The DOS system utility programs will not recognize the extended attributes associated with a file and will cause files to become corrupted. All file and directory management must be performed in the OS/2 environment only. Be sure to run CHKDSK/F when you return to OS/2 from a native DOS environment to ensure that no files have been corrupted. o OS/2 provides integral disk caching and memory optimization functions. Using the equivalent functions that are provided with MS-DOS 6.0 or PC DOS 6.1 is not necessary and might produce errors. o If you use the Dual Boot object, the following message appears: SYS 1714: WARNING! Make sure all your programs have completed or data will be lost when the system is restarted. You requested to start DOS from Drive C. Your system will be reset. Do you want to continue? (Y/N). If you answer the question with a "Y", the system will boot DOS. If you answer the question with a "N", the window will close. At this time, you can click on Windows succesfully. You must answer the question with a "N" in order to continue normal use of the operating system. If you do not answer the question, and instead click on the Window Full Screen object, no action will take place. APPLICATION NOTES: NOTE: For information about changing the DOS settings, refer to DOS settings in the OS/2 on-line Master Help Index. DOS Games --------- For better performance reasons, run in a DOS full-screen session. Change the DOS setting VIDEO_8514A_XGA_IOTRAP to OFF. Animation Works** 1.0 --------------------- Run in 640 x 480 resolution. AutoDesk** AutoCAD** r12 ------------------------ If you are using the r12 version of AutoCAD prior to the C2 level, you will need to obtain a patch from AutoDesk in order for it to work correctly with OS/2. Borland C++ for DOS ------------------- All Borland C++ compilers for DOS and the associated .EXE files require the DPMI_DOS_API setting to be enabled. Borland Paradox 4.0 for DOS --------------------------- Execute pdox.cmd from an OS/2 command prompt to generate an icon for Paradox. Wayne Gretsky's Hockey Game --------------------------- Not supported. Commanche Maximum Overkill -------------------------- Not supported. Terminator game --------------- Must use a joystick. Wing Commander** II ------------------- Set the DOS HW_TIMER setting to OFF. Fotoman** --------- If you have problems running Fotoman, set the DOS COM_DIRECT_ACCESS setting to ON. Intel** SatisFAXtion** ---------------------- This program must be run in a specific DOS session, unless you do the following before you install the program: 1. Make a copy of your AUTOEXEC.BAT file and name it AUTOEXEC.FAX. 2. Install the program. 3. Rename the AUTOEXEC.BAT file FAX.BAT. 4. Rename the AUTOEXEC.FAX file AUTOEXEC.BAT. 5. Make a program object for the SatisFAXtion program. 6. Change the value of the DOS_AUTOEXEC setting for the object to FAX.BAT. 7. Save and exit the Settings notebook. Linkway* Live 1.0 (Tool Series) ------------------------------- Use the following DOS setting to make the demo run properly: DOS_RMSIZE=576 Microsoft MSCDEX ---------------- Change the DOS INT_DURING_IO setting to ON. MSCDEX will only run in a Virtual Machine Boot (VMB) session. Microsoft C/C++ 7.0 Linker -------------------------- If you are using Microsoft C/C++ 7.0 Compiler, Linker, or Codeview, set the DPMI_DOS_API DOS setting to ENABLED. OS/2 APPLICATION COMPATIBILITY o Closing OS/2 applications that use the hardware palette (typically picture viewers or sample graphic applications) occasionally cause a repaint problem on the desktop. If the windows do not repaint correctly, a refresh will restore the desktop, but any windows that are opened or moved will still have the problem. Restarting the system is the only way to completely correct this problem. o If you are using Lotus** 123G or Lotus Freelance Graphics for OS/2 2.0, you need to run the following utility program prior to using these products with XR06100. To run the utility program: 1. Change to the appropriate Lotus directory that contains the application. For example, type CD \123G 2. Back up the LD2CORE.DLL file. For example, type COPY LD2CORE.DLL LD2CORE.BAK 3. Run the update program. Type LD2FIX The Lotus program is now updated. You need to shut down and restart your system for these changes to take effect. o If your system was originally a 2.0 system, the settings of the System Editor object might be incorrect after the installation of XR06100. In order to correct this problem, you must do the following: 1. Open the Productivity folder. 2. Using mouse button 2, click on the System Editor object. 3. Click on the arrow to the right of Open. 4. Select Settings. 5. On the Program page of the Settings Notebook, change the Path and file name field from: E.EXE to: C:\OS2\E.EXE where C is your OS/2 startup drive. APPLICATION NOTES: Communication Manager/2 ----------------------- When using this program with Host Graphics support (HGINST), you might experience shutdown problems. Ensure that the following GDDM fixes have been applied to the host system: UN36882 - MVS UN38883 - VM/SP UN38884 - VM/XA SP UN38885 - DOS/VSE WordPerfect 5.0 for OS/2 -------------------------- If you are using SVGA hardware, you must run this application in VGA mode. WORKPLACE SHELL o With the introduction of OS/2 2.0 XR06100, the method of updating the INI files has changed. Features: 1. You can back up the *.INI files after starting OS/2. 2. Dynamic data exchange (PMDDE.EXE) is loaded automatically whenever you start the system; therefore, it is not necessary to invoke Data Update in the Productivity folder. If this icon appears in your Productivity folder, you can shred or delete it. o If you encounter a situation in which the operating system is not restarting properly, you can reset your desktop to the default system configuration. When the OS/2 Logo Panel first appears, press and hold the left Ctrl, left Shift, and F1 keys until the Workplace Shell desktop appears. This disables the automatic program startup feature of the desktop. o If you start the operating system and you do not see some of the system icons (such as OS/2 System or Shredder), there is a function that will allow you to reset the desktop to its default configuration. WARNING: USING THIS FUNCTION WILL REMOVE ANY DESKTOP CUSTOMIZATION YOU HAVE DONE SINCE YOU INSTALLED THE OPERATING SYSTEM. To perform this function, do the following: 1. Restart the computer. 2. Before the first OS/2 Logo panel appears, hold down Alt+F1 for 20 seconds. When the operating system was installed, certain system files (CONFIG.SYS, OS2.INI, and OS2SYS.INI) were placed in the \OS2\INSTALL subdirectory. When you perform the recovery function described above, the current versions of those files are automatically renamed and are replaced by the default installation versions. If you have a STARTUP.CMD file, that file is also renamed, causing the startup feature to be deactivated. NETWORKS o The Workplace Shell login is not compatible with NetWare** 4.0 Directory Services and should be disabled unless you are using the NetWare 4.0 Bindery Compatibility mode. To disable the login: 1. Edit the CONFIG.SYS file. 2. Remove CONNECTIONS from the SET AUTOSTART statement. 3. Save and exit the CONFIG.SYS file. 4. Restart the system to activate the changes. o If you are using the NetWare Requester Version 2.01 (ships with NetWare 4.0) but have no NetWare 4.0 servers, you can increase the speed of the login process by turning the Directory Services off. To turn the services off: 1. Edit the NET.CFG file in the root directory of the startup drive. 2. Type DIRECTORY SERVICES OFF. This line must be indented with one or more space characters. 3. Save and exit the file. o When applying XR06100 with Netview Distribution Manager/2, the CDM (Change Distribution Management) Agent must be run on a OS/2 2.0 partition. o When installing XR06100 to a LAN Server supporting Remote IPL (RIPL), you must first obtain a special utility package from the IBM Service and Support Center. To obtain this tool, you must request the LAN SERVER RIPL package for XR06100. DISPLAY ADAPTERS (IMAGE, SVGA, XGA, 8514) o The OS/2 operating system will experience video problems similar to those observed in a DOS environment. These problems are due to the failure of a BIOS video mode set. An example of this problem is when the video image on an ALR** Modular PS with a Flexview** 2x SVGA display fails to occupy the entire screen in 1024 x 768 mode. o If you are using an LCD display and have difficulty locating the mouse pointer on the screen, you can increase the size of the pointer if you are using 640 x 480 resolution. To change the size of the pointer (if you have REXX installed): 1. Use an editor to create a file called LARGE.CMD. 2. Add the following information to the file. /* LARGE.CMD Set VGA pointers to large */ /* (c) Copyright IBM Corp. 1993, All rights reserved */ call RxFuncAdd "SysIni", "RexxUtil", "SysIni" call SysIni "USER", "PM_IBMVGA", "CURSOR_SIZE", "1", say Result exit 3. Save and exit the file. 4. At an OS/2 command prompt, type LARGE and press Enter. This program will increase the size of the cursor. To force a standard-size pointer, replace the "1" in the program with a "2". To let the system select the size of the pointer, replace the "1" in the program with a "0". o If you are using the NCR** Safari notebook SSL/25 should modify the following information in the CONFIG.SYS file on your startup drive to allow video register shadowing to be processed correctly in OS/2 2.0 XR06100: change DEVICE=C:\OS2\MDOS\VVGA.SYS to DEVICE=C:\OS2\MDOS\VSVGA.SYS o Systems with image adapters running in dual-display modes will lose DOS window support after a DOS full-screen or OS/2 full-screen session has been started. The system must be restarted to reinstate the DOS window environment. The problem can be avoided by turning off the dual-display mode under the image adapter setup. SVGA Considerations: o The Western Digital** 90C31 SVGA chip set will have video problems when Windows 2.x applications are run. o If you are using a ZEOS** system with Speedstar** VGA, you must run the VMODE utility program supplied with the system to configure the display during the display driver installation. o Zenith Data Systems** with Headland HT208 does not support high-resolution modes even though you can successfully set these modes and install high-resolution drivers. If a high-resolution mode is used, a white half-screen will be displayed. To correct this problem, use the DSPINSTL program to install VGA. o If you have a Sigma Legend** display adapter, you might experience minor video corruption on the desktop when you switch between the desktop and DOS if they are running in different modes. This can be corrected by using a DOS utility program to set the DOS session to the same mode as the desktop. o Tseng ET4000 chip sets, when used with some displays, might cause synchronization problems. This occurs because the default display settings are not set appropriately for these combinations. The following two choices are presented during the installation of SVGA support: 1. Install using a default display type 2. Install using a display adapter utility program You can select the HELP push button to make the correct choice. On certain combinations of ET4000 chip sets used with displays, the choice of "default display type" causes the display to come up unsynchronized when you restart the computer. o During installation of OS/2 2.0 XR06100, the display adapter utility program supplied by the adapter manufacturer should be used. If you attempt to recover without reinstalling OS/2, do the following: 1. To start your computer with the Installation Diskette, insert diskette 1, and escape to a command prompt. 2. Type RENAME x:\STARTUP.CMD *.SAV and press Enter. 3. Type ECHO START /FS /DOS > x:\STARTUP.CMD and press Enter (where x: is your OS/2 startup partition). 4. If you have a display adapter utility program, run it using the instructions supplied with the program. 5. Type the command SVGA ON and press Enter. 6. Type the command ERASE x:\STARTUP.CMD and press Enter. 7. Type the command RENAME x:\STARTUP.SAV *.CMD and press Enter. o If your adapter is a Diamond Speedstar 24, ensure that it is at the BIOS revision level 5.xx or 6.xx. Other revision levels are not supported. o If you are running a WIN-OS/2 full-screen, you must change the DOS setting VIDEO_SWITCH_NOTIFICATION to OFF. XGA Considerations: o If an XGA-2 adapter is installed, and you have modified the default display type in the System Settings notebook (page 2), after you restart the system the resolution for the Workplace Shell may need to be changed. To change the resolution for the Workplace Shell: 1. Open OS/2 System. 2. Open System Setup. 3. Open System. 4. Select a 640 x 480 resolution. 5. Shut down and restart the system. 6. Repeat steps 1 through 3. 7. Select the desired resolution. 8. Shut down and restart the system. o If you are using a dual-display system with XGA as the primary display and VGA as the secondary display, you might see some minor corruption when the XGA display is set to a resolution with 65,536 colors. This corruption will be on the display that does not have focus and will not interfere with the operation of the system. o On dual-display configurations with XGA-2 as the primary display and VGA as the secondary display, the DOS full-screen session might be corrupted if a Windows application is started in a window session. To recover from this situation, select shut down from the pop-up menu and restart the system. o If you are using Dual Boot with an XGA-2 adapter, you must modify the CONFIG.DOS file: 1. Edit the \OS2\SYSTEM\CONFIG.DOS file. 2. Locate the line DEVICE=C:\DOS\EMM386.EXE RAM 2048 X=nnnn-nnnn 3. Change nnnn-nnnn to C000-CFFF. 4. Save and exit the file. o On IBM P75 systems, there might be some corruption on the screen whenever several objects are selected and moved together. This corruption can be eliminated by clicking mouse button 2 to bring up the pop-up menu and then selecting Sort. o An IBM P75 system with an external display attached might only have the 640 x 480 x 16 resolution selection on the System Settings Screen page. If the external display is capable of displaying higher resolutions, use the P75 Reference Diskette to disable the built-in plasma display. o If you are using an XGA system, the hash lines around the icons of open applications might change color unexpectedly. This does not interfere with the operation of the system. o If you are using an XGA system, extra lines might appear on the face of the OS/2 System Clock between the quarter (:15) and half (:30) hour. These lines do not interfere with the operation of the clock. 8514 Considerations: o If you are using the 1MB version of an ATI** Graphics Ultra** Pro adapter, the VGA memory must be set to SHARED to work properly with the OS/2 8514 display driver. This might cause some DOS applications running in the background to corrupt the desktop. To correct this problem, you must upgrade to the 2MB version of the Graphics Ultra Pro and set the VGA memory to 256K or greater. PRINTERS o If you are using the HP** LaserJet** printer driver, some complex images might not print correctly when LaserJet performance options are enabled. If you experience incorrect output or degraded printer performance, return the performance options to the disabled state. To change the performance options: 1. Point to the printer object. 2. Click mouse button 2. 3. Select the arrow to the right of Open. 4. Select Settings. 5. Select the Printer Driver tab. 6. Select Job properties. 7. Change the performance options to their default settings. 8. Double-click on the title-bar icon to close the notebook. o You might experience problems while printing bit maps from an application using the PostScript** printer driver. Select the Printer-specific format option on the Queue options page in the Settings notebook of your printer object. o Your currently installed OS/2 printer driver will be updated by the XR06100 installation program. o Install additional printer drivers from the XR06100 Printer Driver diskettes. NOTE: Do not install the new 32-bit PostScript driver (PSCRIPT.DR_) that came with XR06100 on a system with OS/2 1.3 or OS/2 2.0 without XR06100 installed. It is not compatible with these versions of OS/2. SCANNERS o If you have a Logitech** hand scanner on an ISA bus computer, run the scanner at the 100, 200, or 300 DPI setting. o If you have a HP ScanJet on a PS/2 computer, set the adapter to ROM address C8000-CBFFF and I/O address 268-26F. You may use the Reference Diskette to set the adapter's address, or modify the EMS_FRAME_LOCATION DOS Setting for the DOS session. If the Reference Diskette is used, set the DOS Setting for the DOS session for EMS_FRAME_LOCATION to AUTO. If the ROM address above conflicts with another adapter, try a different address.
