(0.4) Recent Developments

On May 18, IBM announced OS/2 Version 2.1, {{ which became widely available
in the United States on June 14.  }}

Multimedia Presentation Manager/2 (MMPM/2), the OS/2 multimedia extensions,
are now a part of the base operating system (included at no extra charge).
MMPM/2 includes support for sound output (including WAV and MIDI format
files), software motion video (Ultimotion and Intel Indeo formats), and
other advanced multimedia features.

Ultimotion software motion video is the most advanced on the market for
PCs, providing on most hardware, without any assist, up to 320x240 pixel
video images displayed at up to 30 frames per second in 256 colors with an
8- or 16-bit soundtrack.  These video images are properly synchronized with
the sound output thanks to OS/2's preemptive multitasking and
multithreading architecture.  Background tasks continue to operate without
loss of foreground responsiveness to most multimedia operations.

OS/2 2.1 includes drivers for the MediaVision ProAudio Spectrum series of
adapters, Creative Labs SoundBlaster series, and IBM M-Audio.  Other
drivers are expected to be released on vendor bulletin boards.

Note:  SoundBlaster clones may not operate properly with the Creative Labs
drivers in MMPM/2.  MediaVision {{ has released }} a simple patch (to
enable their ThunderBoard to work with the Creative Labs SoundBlaster
driver), and that patch should work with other SoundBlaster clones.  {{ See
(3.6) Multimedia for details.  }}

IBM {{ has released }} a driver which provides limited fidelity sound
output on the standard PC speaker.  This driver does require a substantial
amount of processor attention, so background tasks may experience decreased
responsiveness.  This speaker driver {{ is available from }} OS/2 bulletin
boards, CompuServe, the Internet, and other electronic sources.

The shrinkwrap OS/2 2.1 package now includes over 600 pages of hardcopy
documentation, with extensive information on installation and use of the
operating system.  Moreover, the online documentation (particularly the
online Command Reference) has been enhanced.

Beta testers of OS/2 2.1 will recall that FAX/PM (an applet which could
send one page faxes using Class 2 faxmodems) was part of the product.  This
applet has been pulled from the final release of OS/2 2.1 because it was
found to be far too limiting.  Instead, a new multimedia game, Mahjongg,
has been provided.  Follow the instructions in the OS/2 2.1 README file to
install Mahjongg.

OS/2 2.1 adds several new SuperVGA drivers, all with so-called "seamless"
Windows support (meaning that Windows applications can run alongside OS/2
and DOS applications on the OS/2 Workplace Shell desktop).  The built-in
SuperVGA support extends to display adapters based on most Tseng 4000,
Cirrus Logic, Trident 8900, ATI, Paradise/Western Digital, IBM, and
Headland/Video7 chipsets.  Both the 8514/A and XGA drivers also support
"seamless" Windows.  Text window scrolling speed for SuperVGA adapters has
been improved.  OS/2 2.1 has also routinized the procedure for using video
mode setting utilities (to set customized refresh rates or reset registers
properly).  {{ Drivers for many other SuperVGA adapters based on other
chipsets, including S3, are available through vendor bulletin boards and
other electronic sources.  }}

OS/2 2.1 adds support for Windows 3.1 applications, including enhanced mode
applications.  The OS/2 exclusive features (such as the ability to start
multiple Win-OS/2 desktops) are preserved.  Also, DOS and OS/2 applications
can be started from the Win-OS/2 Program Manager and from other Windows
applications.  Windows 3.1 features, such as OLE and the Windows Multimedia
Extensions, are built into OS/2 2.1, as are most of the Windows 3.1
applets.  VxD (virtual Windows drivers) are not supported under OS/2 2.1
(affecting only a couple applications, notably MathCAD 4.0 and Microsoft
Visual C++).

Support for PCMCIA adapters, Advanced Power Management (for portable and
notebook computers), additional printers (including the DeskJet series and
HP LaserJet 4), most CD-ROM drives, and more SCSI adapters have been added.
Refinements have been made to the Workplace Shell, including drag and drop
icon assignment.  Several new background bitmap images are provided for
tiled backgrounds (like "bricks," "columns," and so forth).

OS/2 2.1 {{ is }} available in three media types:  3.5 inch diskettes, 5.25
inch diskettes, and CD-ROM.  The CD-ROM version includes two 3.5 inch and
two 5.25 inch "bootstrap" diskettes.  These diskettes allow installation of
OS/2 2.1 from the CD-ROM when a native OS/2 driver is in use.  If an OS/2
driver is not available for a particular CD-ROM drive and adapter
combination, a full set of installation diskettes can be built under DOS
from the CD-ROM.  This capability will be familiar to beta testers of OS/2
Version 2.1.  Extensive documentation has been included in the regular
manual to enable the beginner to successfully install OS/2 from this new
media type.  (The CD-ROM and diskette versions of OS/2 2.1 contain the same
documentation, save for an extra one page insert in the CD-ROM package.)

The CD-ROM version is the preferred version of OS/2, since it enables
quicker installation and since it includes extra features not found on the
diskette versions (namely more sample software motion video clips and extra
sound files).  The CD-ROM version is also less expensive to manufacture,
and IBM passes on the savings.  It is also less susceptible to damage by
stray magnetic fields, for example.

OS/2 2.1, like OS/2 2.0, is available in an upgrade version for DOS and
OS/2 users.  This upgrade version includes a "sniffer" utility.  In order
to install the upgrade edition, you must have any version of DOS (PC-DOS,
DR-DOS, or MS-DOS) or OS/2 (IBM OS/2, Microsoft OS/2, or any other version)
installed on your hard disk.  The first time you install the OS/2 2.1
Upgrade Edition the "sniffer" will examine your hard disk to see if you
have one of these operating systems.  If you do, a file will be written to
Diskette 1 of the installation set (or the second bootstrap diskette if
installing from CD-ROM) which will make the Upgrade Edition identical to
the non-upgrade package.  In other words, once the "sniffer" has verified
that a previous operating system is present, it will not attempt to
interfere with any subsequent installation.  This procedure prevents mishap
in the event that the contents of the hard disk are lost due to some
catastrophic failure -- OS/2 2.1 Upgrade Edition can be reinstalled without
any previous operating system on the hard disk.

OS/2 beta testers may install the Upgrade Edition over their existing beta
system, but IBM recommends that they reformat the hard drive early in the
installation, when prompted.  (The "sniffer" will disable itself after
seeing the OS/2 2.1 beta code.)

Unofficially, you may install OS/2 2.1 without reformatting.  This
procedure should only be undertaken by someone who is very familiar with
OS/2.  Start by booting the OS/2 2.1 Installation Diskette, then insert
Diskette 1 when prompted.  At the next prompt, press ESC.  You should then
be left at the command line.  Leave Diskette 1 in Drive A.

Execute the following commands:

 C:

[You should log to the drive where OS/2 is installed.  This example assumes
Drive C.]

 ATTRIB -r -h -s \* /s
 DEL \OS2*
 DEL \README
 DELTREE \OS2
 DELTREE \Desktop
 DELTREE \Nowhere
 DELTREE \Spool
 DELTREE \PSFonts
 DELTREE \Delete
 DELTREE \MMOS2
 RENAME \CONFIG.SYS CONFIG.BET
 RENAME \AUTOEXEC.BAT AUTOEXEC.BET
 A:
 EXIT

[Note that the second DELTREE command should refer to your OS/2 desktop
directory, whatever its name.] Then proceed with installation as directed.

DELTREE is a utility that comes as part of the GammaTech Utilities.  It
deletes a directory and all its contents (including any subdirectories).  A
similar function can be performed using the GNU file utilities ("RM -rf
...").  If you do not have such a utility you will have to use the DEL and
RD commands several times to eliminate all the directories listed in the
DELTREE lines, above.

Do not attempt to perform the above steps under DOS.  Note that you may
want to run CHKDSK from an OS/2 diskette boot (as directed in this List)
prior to installation of OS/2 2.1.

Do not attempt to migrate your INI files unless the utility you use (e.g.
WPSBackup, DeskMan/2) is specifically certified for migration of beta INI
files to the released version of OS/2 2.1.  (Note that in OS/2 2.1 the INI
files may now be copied using the COPY command, even while OS/2 2.1 itself
is running.)

The "sniffer" is satisfied if you have performed a SYS C:  to your hard
disk from DOS, or, in the case of OS/2 2.0, if you have completed
installation through the second insertion of the Installation Diskette (and
the request to remove the Installation Diskette to reboot).  Thus, you do
not have to go to great lengths to satisfy the "sniffer" in the Upgrade
Edition, even if you are starting from an empty hard disk for some reason.
(The "sniffer" is also satisfied if it sees beta OS/2 code.)

In the United States, IBM has priced OS/2 2.1 extremely competitively.
Moreover, discounts for upgrades from OS/2 apply to any previous version of
OS/2 (excluding beta releases), including OS/2 versions from Microsoft and
non-IBM OEMs, including Version 1.x of OS/2.  Through the telephone number
800-3-IBM-OS2, OS/2 2.1 on diskette (Upgrade Edition) costs $119.  On
CD-ROM, the price is $99.  Both prices include shipping.  {{ Rebate
instructions are }} enclosed in the package.  Return {{ your Proof of
License card or original sales receipt from your previous version of OS/2,
your completed OS/2 2.1 registration card, and a copy of your OS/2 2.1
sales receipt to:

 IBM Fulfillment Headquarters
 P.O. Box 525
 Dearborn, MI  48121-0525 }}

and you will receive a rebate check for $30.  Non-upgrade pricing is also
available; call for details.  Additional licenses cost $69 (with a $10
rebate available to users upgrading from OS/2).  These prices are subject
to change after {{ September 14 }}.

IBM strongly encourages users to purchase OS/2 2.1 from dealers.  Pricing
is substantially lower at software dealers such as Egghead Discount
Software.  For users upgrading from OS/2, software dealer pricing is
typically under $50 for the CD-ROM version and under $70 for the diskette
version (after rebate).  Some dealers will even handle all the rebate
paperwork for you (provided you bring in the necessary OS/2 proof of
purchase), automatically reducing the price at the register.

This pricing strategy is designed to encourage software dealers to carry
OS/2 2.1, to provide even more visibility for {{ a successful product
launch }}.  Shifting demand for OS/2 2.1 to dealers is likely to encourage
those same dealers to carry more OS/2 applications.

Technical support for OS/2 2.1 has been enhanced.  The same, free 800
number support made available for OS/2 2.0 is also available for OS/2 2.1
(for up to 60 days following your first call).  Each copy of OS/2 includes
the 60 days of free support, so customers with multiple copies can
effectively get more free support.  The 800 number {{ is now }} dedicated
to OS/2 support, and your call will be directed more quickly and
efficiently.  IBM will continue to work to enhance the support available
through electronic means (such as CompuServe, the OS/2 BBS, the Internet,
and other electronic forums).

IBM's marketing efforts have been expanded for OS/2 2.1.  You will see more
(and improved) advertising in both trade publications and mass market
general publications.

Simultaneous with the release of OS/2 2.1, IBM is now offering a CD-ROM
containing the complete suite of OS/2 and OS/2-related documentation in
electronic form.  This one stop source for OS/2 documentation (including
programming information, information on OS/2-related products such as LAN
Server, MMPM/2 information, and other electronic publications) is in Book
Reader format, and an OS/2 Book Reader program is provided on the CD-ROM.
This CD-ROM is available for $49 from the 800-3-IBM-OS2 telephone number in
the United States.

Also, IBM is releasing the OS/2 2.1 Programmer's Toolkit.  This updated
Toolkit provides utilities and programming information for developing the
best OS/2 applications.  Call IBM's OS/2 Hotline for information on the
Toolkit, or ask your local software dealer.

IBM believes in supporting its customers to the best of its abilities.
That is why IBM will be releasing another Service Pak for OS/2 Version 2.0.
While IBM strongly encourages users to upgrade to OS/2 Version 2.1, some
users may wish to continue running OS/2 Version 2.0.  OS/2 2.1 provides
several new features, and the new Service Pak for OS/2 2.0 will not be
providing such features (such as MMPM/2, Windows 3.1 compatibility,
Advanced Power Management, support for PCMCIA adapters, and so on), but it
will fix all outstanding bugs found in the product to date.  This new
Service Pak will be made available through electronic means (such as
CompuServe and the Internet), and it will also be available for a nominal
charge on diskette direct from IBM.  Expect this Service Pak by the end of
{{ September }}.

Large customers who wish to purchase licenses for 1000 or more copies of
OS/2 2.1 may be allowed to obtain OS/2 2.1 without Windows 3.1 support.
Since Microsoft receives royalties on Win-OS/2 3.1, elimination of this
code can reduce the cost over a large number of copies.  Large customers
who wish to pursue this avenue should speak with their IBM representative.
This offer is not available to smaller customers since IBM cannot supply
custom OS/2 2.1 configurations at a competitive price in smaller
quantities.

OS/2 2.1 pricing and availability will vary from country to country to some
extent.  Contact your local IBM office or IBM dealer for details.  For
example, in the United Kingdom OS/2 2.1 upgrades are available from the
International OS/2 User Group {{ (phone [phone]) for 59 }} pounds
plus VAT and shipping.

{{ Compaq, Everex, }} Northgate, Unisys, AST, and ALR join the ranks of
major system vendors who have agreed to preload OS/2 on request on new
systems.  Dell, Tangent, and Ariel Design will also preload OS/2 on their
new systems on request.

Since OS/2 2.1 is less expensive on CD-ROM and offers several extra
multimedia samples in that format, interest in purchasing CD-ROM drives has
increased.  The advice found in other sections of this List applies.  As a
general rule of thumb, choose a SCSI-2 compliant CD-ROM drive that supports
audio discs, ISO 9660/High Sierra data discs, CD-ROM/XA, and {{
multisession }} Kodak Photo CD.  For the adapter, choose an Adaptec, Future
Domain, DPT, or IBM for easiest, "out of the box" support.  External CD-ROM
drives are generally the safer investment.  Compare drives according to
data transfer speed (the higher the better) and average access time (the
lower the number, in milliseconds, the better).  This advice applies to new
purchases.  If you already have a CD-ROM drive (especially the non-SCSI
Sony, Phillips, and Mitsumi varieties), check CompuServe or other
electronic sources for the appropriate OS/2 driver.

(1.1) What is OS/2?

 What is OS/2?

OS/2 is an advanced operating system for PCs and PS/2s with an 80286
processor or better.  It was codeveloped by Microsoft and IBM and
envisioned as the successor to DOS.

It was designed from the ground up with preemptive multitasking and
multithreading in mind.  "Preemptive multitasking" means that the operating
system is responsible for allocating processor time to the one or more
applications which are running.  (Cooperative multitasking, as found in
Microsoft Windows or the Macintosh's System 7, requires that each
application surrender the processor after a certain amount of time.  If one
application refuses to yield, all the other applications stop running.)
"Multithreading" means that programs can start subtasks which will then be
executed by the operating system in the background.  For example, a word
processor may create a separate thread (subtask) to handle printing or
saving to disk.  When the user asks the word processor to perform one of
these tasks, the word processor creates a new thread and control returns to
the word processor (and the user) immediately.  The subtask is executed by
the operating system in the background.  The user is then free to ask the
word processor to perform another task without waiting for the thread to
complete.  Applications which utilitize multithreading can be much more
responsive to the user.

OS/2 also protects applications from one another (a single misbehaved
program will not typically disrupt the entire system), supports all
addressable physical RAM, and supplies virtual memory to applications as
requested, breaking DOS's 640K barrier.

An OS/2 demonstration diskette (which will run on any PC with VGA or
better, and DOS or OS/2) is available from IBM by calling 800-3-IBM-OS2.
The OS/2 2.1 demo diskette may also be downloaded; see (3.2) Shareware and
Freeware Sources.

(1.2) Differences Between Versions

 What are the differences between versions?

o IBM OS/2 Version 2.1 is the latest release of OS/2, offering Windows 3.1
compatibility, multimedia support (including software motion video), and
more device drivers.  With Version 2.1 IBM has ended the practice of
including extra features in its own, preinstalled versions of OS/2 2.0 that
were not found in the off-the-shelf package.

o IBM OS/2 Version 2.0 is the first release of OS/2 which will run only on
machines with an 80386SX processor or better.  With this release IBM
started developing OS/2 (and its Intel and non-Intel-based successors)
independently but continued to involve third party PC manufacturers in its
testing.  Improvements included an object-oriented Workplace Shell (WPS); a
multiple operating system boot mechanism; better DOS and Windows support
[See (1.3) DOS and Windows Compatibility]; new 32-bit programming
interfaces; support for more than 16 MB of physical RAM [See (2.6) More
Than 16 MB RAM]; and more third party device drivers.  OS/2 1.x
applications, unmodified, still run under OS/2 2.0.

o IBM OS/2 Version 1.3 is the last release of OS/2 to operate on PCs with
80286 CPUs.  This version introduced built-in Adobe Type Manager (ATM) [See
(5.5) Adobe Type Manager], providing scalable typefaces for screen and
printer.  Procedures Language/2 (REXX), a powerful batch-oriented
programming language, became a part of Standard Edition with this release.
[See (5.11) REXX.] (A few OEMs are shipping Microsoft OS/2 Version 1.3, but
Microsoft has ceded all OS/2 development to IBM.)

o OS/2 Version 1.2 was the first to incorporate the High Performance File
System (HPFS) [See (1.5) High Performance File System].  With this release
IBM OS/2 added a dual boot mechanism and IBM Extended Edition [See (3.9)
Extended Services] introduced REXX.

o OS/2 Version 1.1 was the first to include the Presentation Manager (PM)
GUI/API.  Microsoft OEM versions added a dual boot mechanism with this
release.

o OS/2 Version 1.0, introduced in late 1987, was the first release of OS/2.
Task switching was accomplished using a character-based shell and limited
DOS compatibility was provided.

(1.3) DOS and Windows Compatibility

 How good is OS/2 2.1's DOS and Windows compatibility?

OS/2 1.x [See (1.2) Differences Between Versions] justifiably earned a
reputation for poor DOS compatibility.  Since it was hampered by the 80286,
it could not run more than one DOS application at a time.

The situation changed dramatically with OS/2 2.0, and Version 2.1 adds
further refinements.  Version 2.1 preemptively multitasks DOS and Windows
(standard and enhanced mode) applications in separate, protected sessions,
without purchasing either environment.

OS/2 2.1 provides a complete DOS emulation equivalent to DOS 5.0.  The
operating system can provide each DOS application with up to 32 MB of EMS
4.0 (expanded memory), 16 MB of XMS 2.0 (extended memory), and/or 512 MB of
DPMI 0.95 (DOS Protected Mode Interface extended memory), all from its pool
of physical and/or virtual memory (meaning you do not have to have as much
RAM in your system as your applications request).  These limits are in
addition to the up to 730K free conventional memory supplied to each DOS
application, even after mouse and network drivers [See (3.8) Networking
Products] are loaded.  As in DOS 5.0, DOS code and device drivers may be
loaded into high memory.  A 386 memory manager like QEMM is not needed --
these features are provided by OS/2 2.1 directly.

The DOS emulation allows customization of device driver sets -- each DOS
application shares a systemwide CONFIG.SYS and the equivalent of its own
CONFIG.SYS.  Also, there is a systemwide AUTOEXEC.BAT file; however, batch
commands particular to each DOS application can be invoked using separate,
application-specific AUTOEXEC.BAT files.  And many DOS Settings are
provided to fine tune [See (5.6) Performance Tuning] each DOS/Windows
application's behavior (e.g.  IDLE_SENSITIVITY).  Most of the popular
DOS/Windows applications on your hard disk will be migrated automatically
when you install OS/2 2.1.

In addition, OS/2 2.1 will boot one or more specific versions of DOS in
separate sessions, to assist in running particularly difficult applications
(e.g.  DOS networks, MSCDEX {{ and CD-ROM drivers }}).  So, for example, it
is possible to multitask DOS 3.3, DOS 4.0, DOS 5.0, emulated DOS, and
Desqview running atop DOS, all in separate sessions, either windowed or
full screen, all with the same and/or separate device drivers, TSRs,
environment variables, etc.  DOS boot images may be stored on a hard disk.
These procedures are described in the online Command Reference (under
VMDISK), Master Help Index, and in the Installation Guide (Appendix E).
[See also (5.9) Specific DOS Sessions.]

Standard graphics modes [generally up to the resolution of the desktop; See
(2.2) SuperVGA Support] are supported in DOS windows, as are selectable
text mode fonts.  Cut/paste to/from windowed DOS applications is supported
(to/from other DOS, OS/2, and Windows applications), including graphics
cut/paste.  Theoretically, OS/2 2.1 can run up to 240 simultaneous
DOS/Windows sessions; the practical maximum depends on system resources.

OS/2 2.1 will, in fact, run virtually all DOS applications in existence,
including notorious ones such as Microsoft Flight Simulator, Wing
Commander, Maple, MatLab (Version 3.5k or later), and others.  Those that
do not run generally fall into the following categories:

1. Programs that use Virtual Control Program Interface (VCPI) memory
extenders or other extenders which require direct access to 80386 control
registers.  Since such applications are also all but incompatible with
Windows, most vendors have updates for DPMI compatibility;

2. 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 [See (3.4) Disk Utilities].  Fortunately OS/2
2.1 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);

3. 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 2.1's DOS Settings.

4. Certain DOS programming debuggers.  DOS applications running under OS/2
2.1 are not permitted to access 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.

See (3.11) Backup Software for information on OS/2 backup issues.

DOS-based disk caching software is not required since OS/2 includes a
built-in, highly configurable, efficient disk cache.  {{ Also, the OS/2
CD-ROM file system's cache may be adjusted; see the online Command
Reference for details.  }}

DOS programs running under OS/2 2.1 are extremely fast.  A single DOS
application (no other applications open) running full screen under OS/2 2.1
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
up to several times faster than it would if running under native DOS.

If pure DOS is absolutely required, OS/2 2.1 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 DualBoot method {{ (to
switch between DOS and OS/2 only) }} is still available as well.  Consult
the Installation Guide for instructions on how to use Boot Manager or
DualBoot.  Note that OS/2 2.1 need not be installed on Drive C -- it can
reside on other volumes [See (4.3) Hard Disk Partitioning].

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 3.x enhanced mode and standard mode applications under OS/2 2.1,
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 Workplace Shell desktop.  "Seamless" operation is
available in VGA, many SuperVGA, 8514/A, and XGA resolutions with OS/2 2.1
as it ships.  [See (2.2) SuperVGA Support.]

Several icon conversion utilities can convert Windows icons for use by the
OS/2 Icon Editor and/or OS/2-specific programs [See (3.2) Shareware and
Freeware Sources].  (No conversion is necessary if the icons are to be used
with Windows programs running under OS/2 2.1.)

OS/2 2.1 directly provides all Windows enhanced mode features save one:
support for Windows virtual drivers (VxD).  Only two applications are
affected:  MathCAD 4.0 and Microsoft Visual C++.  Services provided by
WINMEM32.DLL are supported.

Windows applications are well integrated into the overall OS/2 Workplace
Shell environment with DDE and Clipboard hooks, and OLE (Object Linking and
Embedding) is supported among Windows applications.  Adobe Type Manager
[See (5.5) Adobe Type Manager] and TrueType for Win-OS/2 comes with OS/2
2.1.  Windows screen (for a full screen desktop) and printer device drivers
will work under Win-OS/2 [See (2.2) SuperVGA Support].  Such notorious
Windows applications as Word, Norton Desktop (save portions described
above), Toolbook, and After Dark work fine under Win-OS/2.  Even
applications which rely on the Windows Multimedia Extensions (supplied as
part of Win-OS/2) operate without trouble.  [See (3.6) Multimedia for
information on the OS/2 multimedia extensions, MMPM/2.] All the Windows
applets (except those made redundant by OS/2's applets) are provided.

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, {{ at the
user's option.  Also, both DOS and OS/2 applications can be started from
the Win-OS/2 Program Manager.  }}

Some Windows applications require 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.  (Note that
several options are available for Win-OS/2 interaction with the Windows INI
files.  For example, the Windows INI files may be migrated during
installation.  Or both Win-OS/2 and Windows can share a single set of INI
files.)

In short, OS/2 2.1 is generally regarded as the most DOS and Windows
compatible among the new crop of 32-bit operating systems (NT included).
It is also generally regarded as a better DOS multitasker than Desqview.

(1.4) Availability and Cost of OS/2

 Where can I buy OS/2, and how much does it cost?

In the United States IBM OS/2 Version 2.1 is available directly from IBM.
Until September 14, promotional pricing is in effect.  OS/2 2.1 can be
ordered directly from IBM by calling 800-3-IBM-OS2.  The price is $119 for
the diskette versions (5.25 or 3.5 inch media) and $99 for the CD-ROM
version (with both 5.25 inch and 3.5 inch "bootstrap" diskettes).  These
prices are for the Upgrade Edition (for customers who already have any
version of DOS or OS/2).  Non-upgrade packages are priced higher.  Both
prices include express shipping.  {{ Rebate instructions are }} enclosed in
each Upgrade Edition package; users of any {{ previous }} version of OS/2
receive a $30 rebate.

IBM part numbers are as follows:  61G0900 for 3.5 inch media, 61G0902 for
3.5 inch media Upgrade Edition, 61G0901 for 5.25 inch media, 61G0903 for
5.25 inch media Upgrade Edition, 61G0904 for compact disc, 71G1877 for
compact disc Upgrade Edition.  An additional license certificate (no media
or manuals) is 61G0910; an additional license Upgrade Edition certificate
is 61G0911.

However, OS/2 2.1 is now available from almost any software dealer
(including Corporate Software, Egghead, Software Etc., and many others).
Software dealer pricing is lower than that available directly from IBM --
often $10 or $20 lower.  With rebate, OS/2 2.1 is about $65 for the
diskette version and about $50 for the CD-ROM version from most dealers.
(The CD-ROM version is less expensive because it costs much less to
manufacture.)

Additional license certificates are available for second and subsequent
copies (with a $10 rebate per Upgrade Edition certificate if upgrading from
any version of OS/2).  However, with the promotional pricing now in effect
it does not make economic sense to purchase license certificates when
upgrading from OS/2.  Through most dealers the CD-ROM package costs the
same as a license certificate, after rebate.  Each CD-ROM (or diskette)
package includes a set of OS/2 manuals and 60 days (per package) of toll
free technical support.  An additional license certificate does not come
with either.

These prices mean that OS/2 2.1 costs about the same as Microsoft Windows
for DOS and roughly one fifth to one third as much as the base (not server)
versions of Windows NT, NeXTStep, Solaris, and UnixWare.

In Canada phone [phone] to order.  In the U.K.  phone the OS/2 User
Group at 0285-655888 or IBM at {{ 0256-841818 or 0800-919-929.  }}.  In
other countries, contact any IBM dealer or office.  Pricing varies from
country to country.

IBM OS/2 Version 1.3 is still available and may be ordered through many IBM
dealers.

IBM is trying to make OS/2 2.1 available everywhere DOS is purchased.  If
your dealer does not stock OS/2 2.1, take your business elsewhere (and
explain why).  IBM bundles OS/2 2.1 with some PS/1, most ValuePoint, and
all 386SX (and above) PS/2 systems.  Several other vendors, including AST,
{{ Compaq, Everex, }} Northgate, ALR, Unisys, Dell, Ariel Design, and
Tangent, will preload OS/2 2.1 on request.

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
(2.1) Hardware Requirements].

(1.5) High Performance File System (HPFS)

 Why should I use HPFS?  What does it offer me?  Does it work with DOS?

HPFS offers long file names (up to 254 characters including the path,
greatly exceeding the "8 dot 3" limit in DOS's FAT file system), contiguous
storage of extended attributes (without the EA DATA.  SF file used by FAT),
resistance to file fragmentation, improved media error handling, smaller
cluster size, support for larger file storage devices (up to 512 GB), and
speedier disk operation, particularly on large hard disks, on systems with
more than 6 MB of RAM.  HPFS is not case sensitive, although it does
preserve case in file names.

However, HPFS is not currently supported on removeable media, although some
programs (e.g.  BACKUP) preserve long file names on such FAT disks.  Also,
native mode DOS cannot access a HPFS partition.  However, DOS/Windows
sessions running under OS/2 can use all files that conform to the "8 dot 3"
naming conventions, even if they are stored on HPFS volumes.

(2.0) Hardware

The following questions are addressed in this section:

 (2.1)  What hardware do I need to run IBM OS/2 2.1?  Do I need a PS/2?

 (2.2)  Will OS/2 2.1 work with my SuperVGA adapter?

 (2.3)  Will OS/2 2.1 work with my printer?

 (2.4)  Can I use COM3 and COM4 in OS/2 2.1?

 (2.5)  Are there any specific hardware recommendations?

 (2.6)  Can I use more than 16 MB of RAM?

 (2.7)  What device drivers are available that aren't included with OS/2?


(2.1) Hardware Requirements

 What hardware do I need to run IBM OS/2 2.1?  Do I need a PS/2?

You need any {{ ISA (AT bus), EISA, VESA LocalBus, or Microchannel }} PC
compatible with at least an 80386SX CPU, 4 MB (6 MB or more strongly
recommended) of RAM, a 60 MB or larger hard disk (with 15-37 MB free,
depending on which features you wish to install), a supported video adapter
(CGA, EGA, VGA, many SuperVGA, 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 [See (3.8)
Networking Products], Extended Services [See (3.9) Extended Services],
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 2.1 and may be deleted, e.g.  DOS,
a 386 memory manager, Windows 3.1, Adobe Type Manager [See (5.5) Adobe Type
Manager] with base typefaces, etc.

The Workplace Shell (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.

{{ The following dual monitor configurations are supported:  VGA or most
SuperVGA with Monochrome Display Adapter (not Hercules), 8514/A with VGA,
XGA with VGA, and XGA with one or more other XGA.  A secondary monitor is
most often used with code debuggers that explicitly support such
configurations.  The Workplace Shell desktop is currently shown only on the
primary display (except for the STB MVP-2 and MVP-4 ISA and Microchannel
display adapters which do support the Workplace Shell desktop spanning
multiple monitors; contact STB at 214-234-8750 or FAX [phone] for more
information).  }}

OS/2 specifically supports hard drive adapters which conform to the Western
Digital chipset interface standard (nearly all MFM, RLL, IDE, and ESDI
adapters) and Adaptec, Future Domain, DPT, and IBM SCSI adapters.  (True
OS/2 2.1 drivers for most SCSI adapters, e.g.  Trantor, Rancho, Procomp,
Corel Systems, BusLogic, Seagate, Mylex, CE Infosys, Ciprico, MediaVision
ProAudio Spectrum, and others are available directly from the adapter
manufacturers or from (3.2) Shareware and Freeware Sources.  A driver for
the Always IN-2000 adapter is available by phoning Columbia Data Products
at 407-869-6700.  Columbia also provides the necessary EPROM and PROM
upgrades.)  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 2.1 driver).

OS/2 driver support is available for the following CD-ROM drives {{ (and

with native OS/2 2.1 support.  The OS/2 CD-ROM support includes audio, ISO
9660/High Sierra, CD-ROM/XA, and Kodak Photo CD compatibility for those
drives which support these standards.

Drivers for non-SCSI Sony CD-ROM drives (e.g.  CDU-535, CDU-31A, and

from Aha Computers (49-4531-17070 or FAX [phone]).  }} Storage
Devices offers OS/2 drivers for its parallel port attached peripherals,
including its CD-ROM drive.  Corel Systems offers a set of OS/2 drivers (in
its "Corel SCSI" package) for many more CD-ROM drives, magneto-optical
drives, and other SCSI devices when attached to any of a number of SCSI
adapters.  DOS device drivers, when installed using a specific DOS session
[See (5.9) Specific DOS Sessions], will still provide CD-ROM services to
DOS/Windows programs for the remainder.

compatibility.

Version 2.1 is explicitly supported on non-IBM PC compatibles.  IBM is
offering a money back compatibility guarantee in the U.S.  Should OS/2 2.1

 Will OS/2 2.1 work with my SuperVGA adapter?

Consult the OS/2 2.1 Installation Guide and Using the Operating System
manuals for complete information on SuperVGA support.

OS/2 2.1 contains built-in 256 color drivers for most SuperVGA adapters
based on the following chipsets:

  o ATI 28800
  o Cirrus Logic CL-GD5422 and CL-GD5424
  o Headland Technologies HT209
  o IBM VGA256C
  o Trident Microsystems TVGA8900B and TVGA8900C
  o Tseng Labs ET4000
  o Western Digital/Paradise WD90C11, WD90C30, and WD90C31 (in WD90C30 mode)

Some SuperVGA adapters (notably ATI's Vantage and Ultra lines) are 8514/A
hardware compatible and will function in 1024x768 256 color mode with
OS/2's built-in 8514/A driver.

Drivers for other SuperVGA adapters (along with installation instructions),
and modified versions of the built-in drivers (such as 16 color versions or
small icon versions) should be available from the adapter vendors directly
or through (3.2) Shareware and Freeware Sources.  In addition, IBM {{ has
released }} a set of drivers for SuperVGA adapters based on S3 chipsets to
these public sources.  (However, certain S3-based adapters require custom
drivers from vendors.)

Regular Windows 3.1 display drivers may be used for the full screen
Win-OS/2 desktop.  To install a Windows 3.1 display driver under Win-OS/2,
simply replace the \OS2\MDOS\WINOS2\SYSTEM\VGA.DRV file with the Windows
.DRV file supplied by the vendor.  (Be sure to make a copy of the original
OS/2-supplied driver file first.)  Note that you may have to use the EXPAND
program supplied with Win-OS/2 to decompress the vendor's .DRV file.

OS/2 2.1 has now routinized the procedure for setting customized refresh
rates using DOS-based utilities {{ (such as VMODE) }}.  You will be
prompted during installation of a SuperVGA driver, and you can specify the
DOS utility you wish to execute along with its parameters (if any).  {{ You
may also need to invoke the utility in your OS/2 AUTOEXEC.BAT file so that
DOS sessions are properly configured to your monitor's specifications.
Read the OS/2 manuals carefully for details on how to use the DSPINSTL
program to install SuperVGA drivers and customize refresh rates for your
monitor.  [Note that for SuperVGA adapters based on the Tseng 4000 chipset
ONLY you may use the command SVGA MONITOR from any full screen DOS session
