		 NCSA Mosaic for Microsoft Windows
		Installation and Configuration Guide

Introduction
------------
This is a step-by-step guide to installing and configuring NCSA Mosaic for
Microsoft Windows.  This guide assumes that the system on which you
are installing NCSA Mosaic meets the following criteria:
    Microsoft Windows is properly installed and configured.
    Utilities such as ftp, pkunzip, and an ASCII editor are available.
    The system is connected to the Internet.

Acquiring the Software
----------------------
Since you are reading this file, you probably already have the NCSA
Mosaic for Microsoft Windows software.  If that is the case, you can skip
this section.

If you do not have the software, start by moving to a location where
applications are normally installed on your system and create a
subdirectory for NCSA Mosaic.  The subdirectory name is arbitrary; the
name mosaic is used here to clarify the following discussion.  Move into
the new subdirectory:
	mkdir mosaic
	cd mosaic

Now you are ready to log on to NCSA's FTP server and download the
NCSA Mosaic files:
	ftp ftp.ncsa.uiuc.edu
	At the login prompt, enter anonymous
	At the password prompt, enter your email address (e.g., 	
		jdoe@business.com)
	get README.FIRST
	cd PC/Mosaic
	ls		(To list the available files and directories)
	bin		(To change to binary mode for the file transfer)
	get wmos20a1.zip

The filename wmos20a1.zip will change with each release and update.  It
will always be in the format wmosversion.zip where version is the current
version number.  For example, wmos20a1.zip is the filename for NCSA
Mosaic version 2.0, alpha release 1.  The next alpha release will be
wmos20a2.zip, and the first beta release of 2.0 will be wmos20b1.zip.

If you have never downloaded PC files from NCSA's server, read the file
README.FIRST now.  It provides useful information that may facilitate
later steps in the installation process.

The file wmos20a1.zip is a compressed archive containing the NCSA
Mosaic executable and several documents, including this guide and a
tutorial when it is available.  Execute the following command to retrieve
the files from the compressed archive:
	pkunzip wmos20a1.zip

Confirming the Files
--------------------
Once you have downloaded and uncompressed the NCSA Mosaic files,
the installation process is straightforward.  Check to make sure all of the
following files exist in the mosaic\ directory:
	update.txt	Current list of this version's enhancements and
			bug fixes in ASCII format.
	install.txt	This guide as an ASCII file
	install.wri	This guide in Microsoft Write format
	mosaic.exe	The NCSA Mosaic executable
	mosaic.ini	The initialization and configuration file for Mosaic
	readme.now	Last minute or emphasized information

Read the file readme.now.  It may contain last minute information that
was not available when this document was prepared.

If you want to review the list of Mosaic enhancements and bug fixes since
the last version, you should read the file update.txt.  Or you can wait
until you have NCSA Mosaic running and read this list online (follow the
links from the Windows Mosaic home page.)

Checking the WinSock DLL
------------------------
NCSA Mosaic is a WinSock 1.1-compliant program and requires that you
have a WinSock 1.1-compliant sockets DLL (winsock.dll) installed to
provide the TCP/IP networking under windows.  Check your WinSock
implementation's installation guide to see whether it is WinSock 1.1-
compliant.

If you are using a commercial TCP/IP stack such as PC-NFS, or running
a local area network such as Novell in addition to the TCP/IP, you must
obtain the WinSock DLL directly from your network vendor.

If your WinSock DLL is not WinSock 1.1-compliant or you do not have a
WinSock DLL installed, and if you are using a stand-alone system on the
Internet, then you can use the shareware Trumpet WinSock.  A
compressed copy of this WinSock implementation can be found on
NCSA's FTP server in the directory PC/Mosaic/sockets/.  Download the
files disclaim.txt and winsock.zip.  (If you want to make sure you have
the latest version of the Trumpet WinSock, it can be acquired via
anonymous FTP from the server biochemistry.bioc.cwru.edu in the
directory /pub/trumpwsk.)

Configuring NCSA Mosaic
-----------------------
To configure NCSA Mosaic, first copy the file mosaic.ini to the directory
\windows. This is important because NCSA Mosaic will not otherwise
recognize and save configuration changes.  Be sure to leave a copy of
mosaic.ini in the mosaic\ directory in case you need to restore any
original entries.

If you are administrating a network site, and want to have one copy of
Windows, and therefore can't put mosaic.ini in the Windows directory,
use the environment variable MOSAIC.INI to specify the pathname of the
INI file.

Edit the file \windows\mosaic.ini as follows using Notepad, edit, or any
other ASCII editor.  General users will not usually need to modify fields
that are not mentioned in the following discussion.

Main section:
-------------
If you can be reached via Internet email, put your full email address in
quotes in the E-mail field.  This is used for annotations and for a return
address when you select Mail to Developers.  If your login ID is jdoe and
you work at Business, Inc., your email entry might read as follows:
	E-mail="jdoe@business.com"

If you do not want NCSA Mosaic to automatically load a document every
time you run it, set Autoload Home Page to no:
	Autoload Home Page=no

If you want to change the first document that is automatically loaded
when NCSA Mosaic is run, change the Home Page entry to point to the
document you want to load.  As distributed, NCSA Mosaic points to a
customized Home Page on NCSA's Web server:
Home Page =
http://www.ncsa.uiuc.edu/SDG/Software/Mosaic/NCSAMosaicHome.html

If you will be using Mosaic over a slow network connection and do not
want inline images to be automatically transferred, set Display Inline
Images to no.  Inline images will be replaced with an NCSA logo:
	Display Inline Images=no

The Grey Background entry allows you to specify whether the NCSA
Mosaic window has a white (no) or grey (yes) background.  Many
documents posted to the Web are tuned to a grey background:
	Grey Background=yes

Fancy Rules toggles a different style of drawing horizontal rules in HTML
documents (the <hr> tag.)
Fancy Rules=yes

List bullets slow down drawing documents.  If you are a speed maven,
you may wish to turn on simplified buillet drawing (line bullets instead of
round bullets.)
Round List Bullets=yes

Settings section:
-----------------
The anchor color is the color of the hyperlink anchors that appear in an
NCSA Mosaic document.  You may set the anchor color to any valid RGB
(red, green, blue) combination.  The RGB values must be separated by
commas and can range from 0 to 255.  As posted on the FTP server, the
default color is blue (0,0,255):
	Anchor Color=0,0,255

In some instances, it is desirable to have NCSA Mosaic underline
hyperlink anchors (e.g, when using a gray scale or monochrome
monitor).  As distributed, NCSA Mosaic is set to underline hyperlink
anchors.  Since underlining slows performance somewhat, you may wish
to set Anchor Underline to no if your system has a color monitor:
	Anchor Underline=no

Mail section:
-------------
Edit the Default Title to contain the message you want to have appear in
the subject line when you send email to the NCSA developers via the
Mail to Developers selection on the Help menu.  As distributed, NCSA
Mosaic enters the phrase "WinMosaic auto-mail feedback":
	Default Title="WinMosaic auto-mail feedback"

Services section:
-----------------
If you want to use NCSA Mosaic's news support, set your network news
(NNTP) server here.  As distributed, NCSA Mosaic specifies the
University of Illinois' NNTP server:
	NNTP Server="news.cso.uiuc.edu"

NCSA Mosaic uses the SMTP server specified here to send mail back to
the NCSA developers when you select Mail developers from the Help
menu. As distributed, NCSA Mosaic specifies NCSA's FTP server
because it is known and almost always available.   If you have a local
SMTP server that you would rather use, edit the entry accordingly:
	SMTP Server="ftp.ncsa.uiuc.edu"

Viewers section:
----------------
This section contains two subsections.  The first subsection contains a
list of file types in MIME (Multimedia mail) form.  The second subsection
specifies the viewer for each of the listed file types.  This information is
used to determine whether an external viewer must be launched to view
a file and, if so, which viewer to launch.

If necessary, edit the */* entries in the second Viewers subsection to point
to your viewers.  If you do not have a viewer for a file type, leave the line
alone.  You may add arbitrary spawning of external viewers by defining a
new TYPE#, specifying a viewer, and optionally providing a suffix list.

NCSA Mosaic must use telnet to connect to some information servers.
To do so, NCSA Mosaic needs to know where to find the telnet
application on your system.  Specify the full pathname for your telnet
application in the telnet entry at the end of the Viewers section:
	telnet="c:\trumpet\telw.exe"

Suffixes section:
-----------------
This section lists the filename suffixes used to identify the file types of
files retrieved via FTP or from HTTP version 0.9 servers.  In such
situations, NCSA Mosaic uses the information in this section and in the
Viewers to determine whether an external viewer must be launched to
view a file and, if so, which viewer to launch.  Files that reside on HTTP
version 1.0 servers are typed by the server and only the information in the
Viewers section is used.

NOTE: If you are retrieving information from an HTTP/1.0 server (most
World Wide Web servers are), the server automatically types data for
you.  The extensions you set up in the Suffixes section will not have any
effect on what MIME type the document is assumed to be, because the
data is already being typed by the server.

You may list any number of filename extensions for a given file type;
simply separate them by commas.

The last suffix listed will be used when writing a file of that type to the
local hard drive.  If your external viewer requires a particular extension,
make sure that it is listed last.

Consider the example of the JPEG file type.  The line
	image/jpeg=.jpeg,.jpe,.jpg
indicates that any file with the suffix .jpeg, .jpe, or .jpg is a JPEG image.
Now look at the preceding section of the file.  The lines
	TYPE3="image/jpeg"
and
	image/jpeg="c:\windows\apps\lview\lview30 %ls"
define a JPEG image as TYPE3 and identify the required external viewer.
Using the information in the Suffixes and Viewers sections of this file,
NCSA Mosaic will recognize files with the extensions .jpeg, .jpe, and .jpg
as JPEG images and know that it must launch the external viewer
lview31 when it encounters them.

Viewers specified in this section must be able to take a specified filename
as a command line argument.

Annotations section:
--------------------
Change the Directory entry to point to the directory on your local hard disk
where you want to store personal annotations.

Change the Default Title to the title you want to use for your personal
annotations.

User Menu sections:
-------------------
This specifies the user-configured menus.  NCSA Mosaic will
accommodate up to ten user-configured menus in any combination of top
level and pop-out menus.  Top level menus (Menu_Type=TOPLEVEL)
will show up in the main menu bar; otherwise, the menu must be listed as
a pop-out from one of the top level menus.

YOU SHOULD REALLY USE THE MENU EDITOR IN MOSAIC TO EDIT THIS SECTION.
Hand-editing can result in screwing up the menus.

User-configured menus are specified as follows.  The first line indicates
the number of the menu while the next one or two lines name the menu
and specify whether it is a top level menu.  If the second user-configured
menu is to be a top level menu named Demos, the first three lines of the
menu specification would be
	[User Menu2]
	Menu Type=TOPLEVEL
	Menu Name="Demos"
If the menu is to be a pop-out menu, omit the second line above.

These initial lines are followed by several lines specifying the items
(Item#) in the menu.  Each Item# line must begin with Item#= and the
rest of the line must be in one of the following formats.  A line specifying
a hotlink must list a document and the URL with which it can be located
separated by a comma:
	Item1=Vatican Exhibit,http://www.ncsa.uiuc.edu/SDG/
		Experimental/vatican.exhibit/Vatican.exhibit.html

A line specifying a menu separator must contain the word SEPARATOR:
	Item2=SEPARATOR

A line specifying a pop-out menu must contain the word MENU and the
number of the pop-out menu, taken from the first line of another user-
configured menu, separated by a comma:
	Item3=MENU,User Menu4

HotList section:
----------------
You can maintain a hotlist of files you wish to have conveniently available.
The hotlist is maintained here and displayed when you select Open URL
on the File menu and press the arrow button on the right side of the
window.

YOU SHOULD REALLY USE THE MENU EDITOR IN MOSAIC TO EDIT THIS SECTION.
This "Hotlist" is also now know as the "QUICKLIST".

You can edit the hotlist directly in this section.  If you want to delete a file
from the hotlist, delete the corresponding line from this section.   If you
want to reorder the files, simply rearrange and renumber the URL# lines.
Note that the entries must be numbered sequentially, starting with URL0.
The easiest way to add a file to your hotlist is to bring the file up in NCSA
Mosaic then select Add Current to Hotlist from the Hotlist menu; if you
prefer, you can add files by editing this section directly.

The Hotlist menu will be merged with the user-configurable menus in a
future release.

Document Caching section:
-------------------------
This sections tells NCSA Mosaic how many documents to cache so that
you do not have to return to the network to retrieve a recently viewed
document.  As distributed, NCSA Mosaic caches five documents:
	Number=5

If you have lots of memory on your system, you can increase the cache
number.  If you have little memory, you may wish to decrease the
number.  If you want to turn caching off, set it to 0 (zero).

Do not modify the Type entry.

Font sections:
--------------
Do not edit this section directly; all font changes must be made from the
Options menu.

Main Window section:
--------------------
Do not edit this section directly; adjust the NCSA Mosaic window size
with the mouse and select Save Window Size on the File menu to save
the new dimensions.

Finding Viewers
---------------
NCSA Mosaic for Microsoft Windows uses external viewers and players
to display certain types of files, such as JPEG images or MPEG movies.
These viewers and players are separate applications and they are neither
maintained nor formally distributed by NCSA.

However, NCSA is always watching for particularly suitable viewers and
players.  When one is located that NCSA can legally distribute, a copy is
placed on NCSA's FTP server in the directory PC/Mosaic/viewers.  If
you do not have a good viewer or player for a particular file type, check
this directory.  If you find a viewer or player for a common data type that
is not in this directory, or is significantly more useful than the one on our
server, please let us know about it.  (One way to communicate that
information is to select Mail to Developers on the Help menu.)

Installing into Microsoft Windows
---------------------------------
You are now ready to install NCSA Mosaic into the Microsoft Windows
system. Select New... on the Program Manager's File menu.  Select
Program Item and click on OK to add NCSA Mosaic to a Program
Group.

Executing and Testing NCSA Mosaic
---------------------------------
Execute NCSA Mosaic now.  If everything is properly configured and
domain name serving is set up, NCSA Mosaic should be able to load
documents successfully.  Test this by selecting Windows Mosaic Home
Page from the Demos menu.

If NCSA Mosaic hangs on execution or misbehaves in any other
unexplained fashion, the most likely source of the problem is the
WinSock DLL.  See "Checking the WinSock DLL" near the beginning of
this guide.

If you are able to execute NCSA Mosaic but selecting Windows Mosaic
Home Page did not work, try the following exercises and include the
results in your query to NCSA.  The results will help NCSA technical
support determine the nature of your problem:
    Select Open Local File on the File menu and try to open a file on
	your system.
    Select Open URL on the File menu and try to open an HTTP file on a
	remote Web server.  The URL
	http://cs.indiana.edu/home-page.html will provide a good test.
    Select Open URL on the File menu and try to open an FTP file on a
	remote Web server.  The URL
	file://cs.uwp.edu/pub/music/kurzweil will provide a good test.

Feedback to NCSA
----------------
Your comments on NCSA Mosaic are important; user feedback is an
integral part of the Software Development Group's (SDG's) planning
activities.  Bug reports are particularly valuable because SDG's tests
cannot duplicate all user environments and equipment configurations.
Bug reports should include enough information to enable SDG
developers to reproduce the problem.  Please specify any information
given by Mosaic, or give us a URL is your problem is reproducible.

To send bug reports, comments, and suggestions, select Mail to
Developers on the Help menu, fill out the form that appears, and click on
Send when it is ready to go.  If Mail to Developers does not work, send
an email message  to the following address:
	mosaic-win@ncsa.uiuc.edu
