OVERVIEW
There are many sources of information available from IBM, including
announcement letters, service manuals, programming and technical reference
manuals, how-to "cookbooks," electronic bulletin boards (both public and
IBM-use only), and others.  The IBM PS/2 Assistant is an attempt to bring much
disparate and often difficult to find information together into one easy-to-use
"electronic book."

The IBM PS/2 Assistant is an online help tool composed of PS/2 and OS/2-related
marketing, service, technical and general information.  The books include the:

 1. IBM PS/2 Marketing Assistant (filename PS2A_MKT.INF), including:

   o IBM hardware and software pricing and part number information.
   o Promotional and upgrade information.
   o IBM publication ordering information.
   o Marketing Qs & As, and more.

 2. IBM PS/2 Service Assistant (PS2A_SVC.INF), including:

   o Hardware and OS/2 error code information.
   o DOS and OS/2 CSD information.
   o Hardware and software service tips and Qs & As, and more.

 3. IBM PS/2 Technical Assistant (PS2A_TEC.INF), including:

   o Tutorials on Micro Channel Advantages, and Expanded vs. Extended Memory,
   o Hardware and software Technical tips and Qs & As, and more.

 4. IBM PS/2 Technical Specifications Assistant (PS2A_TSP.INF), including:

   o Lengthy technical specifications documents for every PS/1 and PS/2 system
     and display, past and present.

 5. IBM PS/2 General Information Assistant (PS2A_GEN.INF), including:

   o IBM and non-IBM telephone numbers.
   o List of OS/2-related BBSes.
   o Acronym and abbreviation list.
   o List of OS/2-related books available in bookstores, and more.

The reason for having a number of different books instead of just one large one
is two-fold.  First, there is so much information provided that it might be
awkward to use, and would take longer to search through than smaller books.
And second, by dividing up all of this information into related subject matter,
those who don't need certain categories of information (such as service tips,
for example), can delete entire books to save disk space.  Besides, these files
may be logically linked together and viewed or searched as one large book, at
your preference.  (This procedure is explained in the accompanying PS2ASST.TXT
file.)  For convenience, the files will be collectively called the "PS/2
Assistant" throughout the rest of this document.

Not only is the information more "centrally located" this way than distributed
across all the individual documents, but due to its electronic nature, the
specific information you seek can be found more quickly and easily.  The source
information is compiled into binary files that take roughly half as much disk
space as ASCII files would.  And since the compiler also creates a "data
dictionary" of all words and numbers anywhere in the files, all occurrences can
be found and displayed on-screen in only a few seconds via the search facility
provided.  In addition, hypertext links (hyperlinks) allow you to jump from
section to section within a book without ever having to return to the Table of
Contents.  Hyperlinks are also used to display popup footnote windows at the
point of the footnote reference, rather than making you have to scroll down to
the bottom of a page, or the end of a chapter, to find the footnoted
information.

The PS/2 Assistant is created by compiling a scripted ASCII text file, using
the Information Presentation Facility (IPF) Tag Language and Compiler.  They
are included in the OS/2 V1.2 and 1.3 Programming Tools and Information
toolkits (P/Ns 6024929 or 85F1671).  The PS/2 Assistant requires OS/2 1.2 (or
later) to operate, because it uses the OS/2 VIEW.EXE command to access the
files.  This is the same command used to display the online OS/2 Command
Reference.  Since both files were created with the same compiler, and are
displayed by the same command, they look and act very much alike.  So if you
know how to use one, you also know how to use the other.

Note:  The PS/2 Assistant was tested, and does work, across an OS/2 LAN Server
V1.2 or 1.3 network, relieving the need for disk space on the requester, not to
mention not having to keep all those requesters updated with the latest
versions of the PS/2 Assistant books.  (For instructions on Setting Up an OS/2
LAN Server to Share Online Books, see the document by the same name in the
Networking Tips section of the PS/2 Technical Assistant.)

HOW TO USE THE PS/2 ASSISTANT
Before you begin to use this tool, it is helpful to understand how to:

o Expand the Contents to see all available topics
o Obtain additional information for a highlighted word or phrase
o Use action bar choices.

How to use the Table of Contents
When the Contents window first appears, some topics have a plus (+) sign beside
them.  The plus sign indicates that additional topics are available.

To expand the Contents if you are using a mouse, click on the plus sign.  If
you are using the keyboard, use the Up or Down Arrow key to highlight the
topic, and press the plus (+) key. For example, PS/2 Part Number / Pricing /
Availability List has a plus sign beside it.  To see the complete list of Part
Numbers, etc, click on the plus sign or highlight that topic and press the plus
(+) key.

To view a topic, double-click on the topic (or press the Up or Down Arrow key
to highlight the topic, and then press the Enter key).

Note:  To exit from any panel (window), including this one, simply press the
ESC key, or double-click on the icon to the left of the panel title bar (NOT
the one to the left of the PS/2 Assistant title bar, or you will close the PS/2
Assistant).  This will return you to the point from which you entered the panel
(either the Table Of Contents or another panel).  This may be done a number of
times in succession to step back through layers of panels, or until the TOC is
reached.

How to obtain additional information
After you select a topic, the information for that topic appears in a window.
Words, phrases, or numbers highlighted like this or this indicate that
additional information is available, either in the form of a footnote, or
sometimes an entire section.  Hyperlinks are used in some areas to help you
jump from one section of a document directly to another, without having to
return to a menu. (If you don't find this color to be easily identifiable as a
hyperlink, you may change the color, as described below.)  Use the mouse, or
Tab and Enter keys, to move between all the hyperlinks within a document.  For
example:

Certain words in the following section are highlighted in this way.  If you are
using a mouse, double-click on the highlighted words.  If you are using a
keyboard, press the Tab key to move from one highlighted word to the next, (or
Shift-Tab to backup) and then press the Enter key.  Additional information will
appear in a pop-up window.

Note:  The windows that pop up when you double-click on a hypertext link are
sizable.  Simply drag the sides or corners of the windows to the desired size
and shape, just as you would any other PM window.

Note:  Headings are assigned the color red throughout the PS/2 Assistant. The
Change Bars (|), which indicate additions or revisions since the last release
of the PS/2 Assistant, are also highlighted in red to make them easier to find.
(All other colors are as set by your OS/2 Control Panel selections.  If a
color, or combination of colors, is not to your liking, you may change them to
something more pleasing. The operative choices are:  Help Text, Help
Background, and Help Highlight.)

Tip:  An easy way to find ALL changes since the last version is to Search for
the Change Bar character (|).  This can be typed by holding the Shift key while
typing the backslash key.

How to use the Action Bar options
A number of choices are available for managing information presented in the
PS/2 Assistant.  If you want to see more information about these choices, click
on the name of the choice (or press the Tab key to move to the choice and press
Enter).

Help
      Provides online help panels for using the Help facility.

Bookmark
      Allows you to set a placeholder so you can retrieve information of
      interest to you. (This choice is available from the Services pull-down.)

Search
      Allows you to find occurrences of a word or phrase in the current topic,
      selected topics, or all topics. (This choice is available from the
      Services pull-down.)

Print
      Allows you to print one or more topics. (This choice is available from
      the Services pull-down.)

Copy
      Allows you to copy a topic you are viewing to a file you can edit. (This
      choice is available from the Services pull-down.)

Options
      Allows you to change the way your Contents is displayed.

ΓòÉΓòÉΓòÉ 5.3.1. PS/2 Model 25 LS ΓòÉΓòÉΓòÉ

Because the two types of Model 25 LS are identical except for a choice of
monochrome vs. color display, both will be represented by the one document, to
follow.  Unless otherwise indicated, all product information applies equally to
both types.

What makes the LS models different from the standard Model 25s is the presence
of a 4 Mb/sec Token Ring Network Adapter in the long slot, and the lack of a
space-saving keyboard option.

ΓòÉΓòÉΓòÉ 5.7.1. PS/2 Model 35 LS ΓòÉΓòÉΓòÉ

Because the Model 35 LS models are identical, except for a choice of Token-Ring
(Model 8535-24X) or Ethernet (Model 8535-14X) network adapter, they are
represented by the one document, to follow.  Unless otherwise indicated, all
information applies equally to both LS models.

What differentiates the LS models from the SX models is the presence of a
network adapter in one of the adapter slots (which reduces the number of
available slots), and the lack of any diskette or fixed disk drives (which may
be added later) in the system.

The PS/2 Models 35-040, 35-043, 35-4B1, and 35-4B2 are identical except for the
lack of a fixed disk drive in the 040, the size of the fixed disk drive in the
other models, and the inclusion of a color display with the 4B1 and 4B2 models.
Therefore both models will be covered by this one document.  Differences will
be indicated by model number in parentheses.

ΓòÉΓòÉΓòÉ 5.13.1. PS/2 Model 55 LS ΓòÉΓòÉΓòÉ

Because the Model 55 LS models are identical, except for a choice of Token-Ring
(Model 8555-LT0) or Ethernet (Model 8555-LE0) network adapter, they are
represented by the one document, to follow.  Unless otherwise indicated, all
information applies equally to both LS models.

What differentiates the LS models from the SX models is the presence of a
network adapter in one of the adapter slots (which reduces the number of
available slots), and the lack of any diskette or fixed disk drives (which may
be added later) in the system.

Note:  This model is being withdrawn as of 05/25/92.

ΓòÉΓòÉΓòÉ 5.14.1. PS/2 Model 56 LS ΓòÉΓòÉΓòÉ

Because the Model 56 LS models are identical, except for a choice of Token-Ring
(Model 8556-24X) or Ethernet (Model 8556-14X) network adapter, they are
represented by the one document, to follow.  Unless otherwise indicated, all
information applies equally to both LS models.

What differentiates the LS models from the SX models is the presence of a

═══ 5.15. PS/2 Model 56 386SLC Systems ═══

This section contains feature and technical specification information for the
386SLC-based Model 56 systems.  These are differentiated from the "standard"
Model 56 SX systems by the use of the 386SLC chip, rather than the 386SX.

ΓòÉΓòÉΓòÉ 5.15.1. PS/2 Model 56 SLC LS ΓòÉΓòÉΓòÉ

Because the Model 56 SLC LS models are identical, except for a choice of
Token-Ring (Model 8556-25X) or Ethernet (Model 8556-15X) network adapter, they
are represented by the one document, to follow.  Unless otherwise indicated,
all information applies equally to both LS models.

What differentiates the LS models from the SX models is the presence of a
network adapter in one of the adapter slots (which reduces the number of
available slots), and the lack of any diskette or fixed disk drives (which may
be added later) in the system.
