- Commander, Maple, MatLab (Version 3.5k or later), and others. Those
- that do not run generally fall into the following categories:
-
- (a) Programs that use Virtual Control Program Interface (VCPI) memory
- extenders or other extenders which require direct access to the 80386
- control registers. Since such applications are also all but
- incompatible with Windows, most vendors have program updates for DPMI
- compatibility;
-
- (b) Applications which attempt to directly address the physical sectors
- of an OS/2 managed nonremoveable hard disk drive. Such programs include
- UnErase in Norton Utilities, for example. Fortunately OS/2 2.0 has a
- built-in UnDelete feature which is more robust than Norton's approach.
- (Consult the online Command Reference for information on how to enable
- UNDELETE);
-
- (c) Timing sensitive DOS applications. Certain DOS programs that
- generate digitized sound through the PC's internal speaker may have
- distorted sound. High speed, real time data collection may be
- compromised. These problems can often be minimized or even eliminated
- using OS/2 2.0's DOS Settings.
-
- (d) Certain DOS programming debuggers. DOS applications running under
- OS/2 2.0 are not permitted to access the debug registers DR0-DR7 from a
- DOS session. Also, DOS debuggers will not be able to set hardware
- breakpoints, and all read/write operations to debug registers in virtual
- 8086 mode will be ignored.
-
- Generally DOS backup programs will work under OS/2 2.0, but they may not
- capture some of the OS/2 data (especially extended attributes) on the
- hard disk without the assistance of utilities such as EABK201 (available
- from shareware/freeware sources; see Question 9). OS/2 backup tools are
- available, notably IBM's PMTape and PS2Tape (for IBM and Irwin tape
- systems), Sytos Plus (Sytron, 508-898-0100), EZTape (Irwin, 313-930-
- 9000), Intelligent Backup (Sterling, 916-635-5535), FileSafe (Mountain,
- 408-438-2665), KeepTrack Plus (Finot, 800-748-6480), NovaBack (NovaStor,
- 818-707-9900), and MaynStream (Maynard, 407-263-3500). The OS/2 BACKUP
- utility is best used from an OS/2 diskette boot (see Question 13). DOS-
- based disk caching software is not required since OS/2 includes a built-
- in, highly configurable, efficient disk cache.
-
- DOS programs running under OS/2 2.0 are extremely fast. A single DOS
- application (no other applications open) running full screen under OS/2
- 2.0 typically achieves 95-97% of the performance it would have under
- native DOS. If the DOS application performs any disk I/O it can
- actually operate faster than it would if running under native DOS. It
- is not unheard of for disk intensive DOS applications to run twice or
- even three times as fast under OS/2 2.0.
-
- If pure DOS is absolutely required, OS/2 2.0 includes a utility called
- the Boot Manager. The Boot Manager can provide a listing of all the
- operating systems available on the system and will allow selection of
- any one at startup, with a default after timeout. The OS/2 1.x DualBoot
- method is still available as well. Consult the Installation Guide for
- instructions on how to configure your system to use Boot Manager or
- DualBoot. Note that OS/2 2.0 need not be installed on Drive C -- it can
- reside on other volumes.
-
- Compatibility with Windows, a popular DOS extender, is provided by Win-
- OS/2, an environment based on Microsoft's Windows source code. It runs
- Windows 2.x and 3.0 real mode and standard mode applications under OS/2
- 2.0, either on a full screen Windows desktop (with the familiar Program
- Manager and one or more Windows applications) or "seamlessly," alongside
- OS/2 applications on the WPS desktop. "Seamless" operation is available
- in VGA resolution with OS/2 2.0 as it ships; see Question 11 for
- information on third party drivers.
-
- CVTICO or ICON, both available from shareware/freeware sources (see
- Question 9), will convert Windows icons for use by the OS/2 Icon Editor
- and/or OS/2-specific programs. (No conversion is necessary if the icons
- are to be used with Windows programs running under OS/2 2.0.)
-
- OS/2 2.0 directly provides Windows enhanced mode features save one:
- services included in WINMEM32.DLL. Windows applications which utilize
- this DLL (e.g. Mathematica 2.0, Omnipage Professional 1.0) will not run
- under OS/2 2.0. Fortunately the number of WINMEM32 applications is few,
- and apparently the vendors of such applications will be shipping OS/2
- 2.0 compatible updates.
-
- Windows applications are well integrated into the overall OS/2 WPS
- environment with DDE and Clipboard hooks, and OLE 1.0 is supported among
- Windows applications. Adobe Type Manager for Win-OS/2 comes with OS/2
- 2.0 (see Question 25). Windows screen (for a full screen desktop) and
- printer device drivers will work under Win-OS/2. Such notorious Windows
- applications as Word for Windows, Norton Desktop (save portions
- described above), Toolbook, and screen savers such as After Dark work
- fine under Win-OS/2. Even the Windows Multimedia Extensions (and
- programs which utilize them) operate under Win-OS/2. (For information
- on Multimedia Presentation Manager/2, the OS/2 2.0 multimedia
- extensions, call 800-426-9402 ext. 150.)
-
- Win-OS/2 departs from Microsoft Windows in that it allows more than one
- Windows desktop and can preemptively (rather than cooperatively)
- multitask Windows applications in separate, robust, protected sessions.
- Also, while the enhancements incorporated into Windows 3.1 are
- functionally incorporated into Win-OS/2, Win-OS/2 is not technically
- Windows 3.1 compatible. IBM has demonstrated 3.1-level Win-OS/2, and it
- is widely rumored that a free 3.1-level update will be available this
- fall. Aside from the Windows 3.1 applets there are no Windows 3.1-
- specific applications available. (Win-OS/2 will run the Windows 3.0
- applets, but it does not include them. Instead, true OS/2 2.0
- spreadsheet, database, communications, time planning/scheduling, and
- other applets are provided.)
-
- Some Windows applications require OLE DLLs or custom settings in
- WIN.INI. If such a Windows application has been installed under the DOS
- version of Windows, Win-OS/2 may not be able to find the appropriate
- files or configuration. Try reinstalling the Windows application under
- Win-OS/2.

- ------------------------------
-
- (5) Where can I buy OS/2?
-
- IBM OS/2 Version 2.0 is available from most software dealers (including
- Elek-Tek, 708-677-7660; and Corporate Software, 800-677-4000) and
- directly from IBM (800-3-IBM-OS2, 800-465-1234 in Canada). In the U.K.
- call the OS/2 User Group (0285-655888) to order. OS/2 2.0 on 3.5 inch
- diskettes is part no. 84F7586. For 5.25 inch diskettes, 10G2991. Media
- are high density. For compact disc, 10G2992. IBM OS/2 Version 1.3 is
- still available and may be ordered through many IBM dealers.
-
- IBM is trying to make OS/2 2.0 available everywhere DOS is purchased.
- If your dealer does not stock OS/2 2.0, take your business elsewhere
- (and explain why). IBM also has plans to bundle OS/2 2.0 with new PS/1,
- PS/2, and non-IBM systems.
-
- Microsoft versions of OS/2 1.x are available only through OEMs (e.g.
- Compaq, Dell) or by purchasing Microsoft's LAN Manager 2.1 or SQL Server
- products. Microsoft has all but ceased OS/2 development, working
- instead on Windows and the future, high-end NT (formerly OS/2 3.0).
-
- ------------------------------
-
- (6) How much does OS/2 2.0 cost?
-
- IBM OS/2 2.0 retails for $195. However, in the U.S. introductory
- pricing is available through October 31, 1992, by calling IBM's order
- line (800-3-IBM-OS2). Upgrades are $79 from any version of Windows, $99
- from any version of DOS, and $149 without an upgrade. (Call for details
- on upgrades from OS/2 1.x.) Similar promotions are in effect in Canada
- and other countries. Special pricing is available for multiple OS/2
- licenses. Educational discounts are available but may not apply to the
- introductory prices. (IBM's educational inquiries line in the U.S. is
- 800-222-7257.)
-
- IBM offers two money back guarantees in the U.S.: a 30-day, no questions
- asked, money back guarantee, and a 90-day compatibility guarantee (see
- Question 7).
-
- ------------------------------
-
- (7) What hardware do I need to run IBM OS/2 2.0? Do I need a PS/2?
-
- You need any PC compatible, PS/1, or PS/2 with at least an 80386SX CPU,
- 4 MB (6 MB or more strongly recommended) of RAM, a 60 MB or larger hard
- disk (with 15-30 MB free), a supported video adapter (CGA, EGA, VGA,
- 8514/A, XGA, or third party driver) with appropriate display, and a high
- density 3.5 or 5.25 inch floppy drive for installation. A mouse or
- other pointing device is strongly recommended. Allow extra RAM and hard
- disk space for OS/2-based networking, ES, and/or extra system loads
- (i.e. an extraordinary number of large applications running
- simultaneously). When calculating hard disk space requirements,
- subtract space occupied by files already on the hard disk which are
- functionally included in OS/2 2.0 and may be deleted, e.g. DOS, a 386
- memory manager, Windows, Adobe Type Manager with base typefaces, etc.
-
- The WPS will not operate with the Monochrome Display Adapter or the
- Hercules Monochrome Graphics Adapter. Usually the WPS will fail to work
- with monochrome EGA. However, some EGA adapters (e.g. Paradise
- Monochrome EGA Card, ATI EGA Wonder) will emulate all color EGA modes on
- TTL monochrome monitors and, thus, will work with the WPS.
-
- On (E)ISA bus machines, OS/2 specifically supports hard drive adapters
- which conform to the Western Digital chipset interface standard (i.e.
- nearly all MFM, RLL, IDE, and ESDI adapters) and Adaptec, Future Domain,
- and IBM SCSI adapters. (True OS/2 2.0 drivers for some SCSI adapters,
- e.g. Trantor and Procom, are available directly from the adapter
- manufacturer.) In addition, "generic" INT13 support is provided for all
- other hard disk adapters. This "generic" support even embraces such
- devices as Iomega's Bernoulli and SyQuest's removeable media products
- (but for best results contact Iomega or SyQuest for an OS/2 2.0 driver).
- CD-ROM support is included as well. At present the OS/2 CD-ROM driver
