However, some applications, usually because of their design or because they use undocumented interfaces, will not operate properly with OS/2 2.0. IBM is in the process of contacting these vendors about resolving these incompatibilities. These applications are: Application programs that use virtual control-program interface (VCPI) memory extenders: Other DOS extenders, such as VCPI, that require exclusive access to the 80386 control registers, are not supported because they could violate the integrity of OS/2 2.0. We support application programs that use DOS Protect-Mode Interface (DPMI), Expanded Memory Specification (EMS), or the Extended Memory Specification (XMS).. Windows enhanced-mode programs: Enhanced-mode programs requiring the dynamic link library, WINMEM32.DLL, are not supported. However, Microsoft Windows Version 3.0 enhanced-mode programs written to comply with DPMI are supported. Application programs that directly address the physical sectors of OS/2 managed non-removeable DASD: Functions in programs that directly address the physical sector to perform write operations are not supported, because these operations will generally destroy the OS/2 2.0 file system integrity. Windows programs that call the Windows mini-programs: Some Windows applications allow the user to invoke the Windows mini-programs to run a subset of function. If you had Windows Version 3.0 on your system and did not format your hard disk when you installed OS/2 2.0, these mini-programs ** Trademark of the Microsoft Corporation + Copyright IBM Corp. 19923 1 ******************** Page: 4 ******************** are called automatically. Otherwise, in most cases, access to these mini-applications is optional and does not cause any functional loss in the application itself. Timing sensitive DOS applications: DOS programs that generate digitized sounds through the speaker will not run at full speed. Turning off the sound will help the programs run faster. Certain DOS communication applications that require more than 1000 interrupts per second or require a high level of interrupt service might not work. DOS debuggers: Under OS/2 2.0, DOS applications cannot access the debug registers (DR0-DR7) in a DOS session. DOS debuggers will not be able to set hardware breakpoints in OS/2 2.0, and all read and write operations to debug registers in virtual 8086 (V86) mode will be ignored. DOS running under WIN-OS/2:* At the present time, WIN-OS/2 does not allow you to start DOS sessions from within WIN-OS/2. While testing is continuing, current compatibility information about applications is available through your dealer or Marketing Representative, as well as through the following: Prodigy (call the appropriate phone number for your area, or Membership Service at (914) 962-0310). CompuServe (call the appropriate phone number for your area, or Membership Service at 1-800-848-8199). IBM National Support Center Bulletin Board System (NSC BBS).

Application Programs5 1 ******************** Page: 6 ******************** 6 OS/2 2.0 Compatibility Information 1 ******************** Page: 7 ******************** Graphical Applications Programs OS/2 2.0 supports a broad variety of display-adapter hardware; for example, Video Graphics Array (VGA), Extended Graphics Array (XGA* ), 8514, Enhanced Graphics Array (EGA), and Color Graphics Array (CGA). It allows OS/2 programs, DOS programs, and Windows programs to run in both window sessions and full-screen sessions. OS/2, DOS, and Windows programs can run successfully in both the foreground and the background. Typically, the OS/2 user need not be concerned with the graphics modes that are used within a program, or whether a program will run successfully in a background session. Some types of display adapters do, however, place limits on the ability of the OS/2 operating system to run certain classes of DOS and Windows graphics programs in the background. The limits are because of the difficulty of providing virtual access to the display-adapter hardware without disturbing either the foreground session or other background sessions. Under certain conditions, DOS applications that use graphical display modes will become suspended in background sessions when they attempt to write to the display. The following summarizes the conditions under which OS/2 2.0 limits the running of some DOS and Windows programs. When running on VGA graphics hardware: DOS applications that use the higher resolution VGA and EGA graphics modes to write to the display will be suspended when the application is in a background session and the system desktop does not have control of the display. When running on XGA hardware, and OS/2 2.0 has been installed so that Presentation Manager* (PM) is running in XGA mode: * Trademark of the IBM Corporation + Copyright IBM Corp. 19927 1 ******************** Page: 8 ******************** DOS applications that use XGA graphics modes or the higher resolution VGA and EGA graphics modes will be suspended when the application is in a background full-screen session. They cannot be run in a window on the system desktop. When running on XGA graphics hardware, and OS/2 2.0 has been installed so that PM is running in VGA mode: DOS applications that use the higher resolution VGA and EGA graphics modes to write to the display will be suspended when the application is in a background session and the system desktop does not have control of the display. When running on 8514 graphics hardware, and OS/2 2.0 has been installed so that PM is running in 8514 mode: DOS applications that use 8514 graphics modes will be suspended when the application is in a background full-screen session. They cannot be run in a window on the system desktop. When running on 8514 graphics hardware, and OS/2 2.0 has been installed so that PM is running in VGA mode: DOS applications that use the higher resolution VGA and EGA graphics modes to write to the display will be suspended when the application is in a background session and the system desktop does not have control of the display. When running on EGA graphics hardware: DOS applications that use the higher resolution EGA graphics modes to write to the display will be suspended when the application is in a background session and the system desktop does not have control of the display. The display drivers provided for WIN-OS/2 full-screen sessions are designed so that they write to the display only when the session is in the foreground. They suppress all background write operations in a way that allows a WIN-OS/2 program to continue to run while the session is in the background. When the session assumes the foreground, the WIN-OS/2 program is automatically prompted to redraw itself. 8 OS/2 2.0 Compatibility Information 1 ******************** Page: 9 ******************** When using WIN-OS/2, use a Windows display driver that suppresses background writing to the display. Otherwise, background WIN-OS/2 full-screen sessions might be suspended under conditions similar to those described above for DOS applications. The table on page 11 summarizes the preceding information. While testing is continuing, current compatibility information about applications is available through your dealer or Marketing Representative as well as through the following: Prodigy (call the appropriate phone number for your area, or Membership Service at (914) 962-0310).

Graphical Applications Programs9 1 ******************** Page: 10 ******************** USING THE TABLE: To determine under what conditions your applications will run in a background session: 1. Find your graphical display hardware in the ■Type of Video┐ column. 2. Find your System Desktop Mode. 3. Read across the table to your application column. For example, assume you have a DOS application using VGA mode on a system with VGA video. The application is in full-screen. To determine if the application will be suspended: 1. Find your type of video (VGA) in the ■Type of Video┐ column. 2. Find your System Desktop Mode (VGA). 3. Read across the table to your application column (DOS Application, Matches Desktop Mode, Full-Screen). The PF indicates that the DOS application runs when PM has control of the screen or when the application is in a foreground session. 10 OS/2 2.0 Compatibility Information 1 ******************** Page: 11 ******************** Windows Apps Full Screen (FS) DOS Apps Matches Matches System VIO Desktop Using VGA WIN-OS/2 Desktop Using VGA Type of Desktop PM OS/2 Mode Mode Window Mode Mode Video Mode Apps AppsABAB (Win) FS Win FS Win XGA XGARFRFRF n/aFxFx XGA VGARFR PFR PFR PF PF' PF PF' VGA VGARFR PFR PFR PF PF' PF PF' 8514 VGARFR PFR PFR PF PF' PF PF' 8514 8514RFRFRR n/aFxRR EGA EGARFR PF n/a n/a n/a PF PF' n/a n/a CGA CGARFRR n/a n/a n/aRR n/a n/a Legend: R Runs PF Runs when PM has control of the screen, or when the application is in a foreground session F PF' Runs only when the application is in a foreground session Runs only when PM has control of the screen x Not supported n/a Not applicable Note: Column A indicates the use of a Windows display driver that suppresses background output.
