Installation of Opera
Hardware Requirements
Minimum configuration
386 PC with 6 Mb RAM and 2 Mb free disk space.
Recommended configuration
486 PC or better with 8 Mb RAM at least and 4 Mb free disk space.
Installation
1. If Windows is not already running, start it.
2. Put the Opera installation disk in your floppy disk drive.
3. Choose 'Run' from the Windows Program Manager 'File' menu.
4. Type a:\install or b:\install to match the floppy drive you have placed the disk
in, it will normally be a: .
5. Follow the screen instructions.
Important options to set after installation.
To unlock the full power of Opera, it is important to customise
some of the options after the program has been installed. Therefore you should start
the program, by clicking on the Opera icon in the Opera program group, and follow
the instructions below.
Communications module (winsock)
Opera must have a communications module in order to contact the rest of the world.
This must support Windows Socket 1.1. If the version of Opera you purchased does
not contain such a module, or you wish to use something else, you may have to change
some of the settings under Advanced preferences.
There are many different communications modules available on the market. Even if
these in theory conform to the same standard, there are occasionally significant
differences in implementation, and even some incomplete implementations. To facilitate
fast loading of single or multiple documents simultaneously,
Opera must have a fully featured communications module. To handle problematic modules
Opera has several options to be found under Advanced preferences. Most users will
not need to bother with this, but if you experience communications problems, it
can be worthwhile changing some of these parameters. Any problems are most likely
to occur when loading multiple documents simultaneously.
Some known problems:
PC-NFS 5.0
If you have an old version of PC-NFS 5.0, it would be better to upgrade it. You
can retrieve this from the Internet or by contacting your PC-NFS supplier. Version
5.0 can also give errors when you define too big a network buffer from within Opera.
If you continue to have problems try setting it to 1 kB.
Microsoft TCP/IP
Older versions of Microsoft TCP/IP require you to use the Synchronous Domain Name
Service (DNS) when you run Opera .
This is how to set up the Synchronous Name Service and the size of the network buffer:
1. Choose Advanced... from the Preferences menu.
2. Change the size of the network buffer (if necessary).
3. Put a cross on 'Synchronous DNS'.
4. Click on the OK button.
If you have tested using both the Synchronous DNS and changing the size of the network
buffer, without success, you can also try setting the total number of connections
down to eg. 1, both as a total and to a single server. Opera will run slower but
behave better with the communications module.
Proxy servers
A proxy server is a machine that retrieves documents on command. The advantage of
a proxy server is that it caches documents and so provides a markedly faster retrieval
service than going direct, eg. to a server in
another country. Opera has currently no direct support for the WAIS and Gopher protocols,
but needs to use a proxy server to retrieve documents from that type of server.
You should ask your network support personnel or your Internet supplier about their
proxy servers.
This is how you set up proxy servers:
1. Choose Proxy servers... from the Preferences menu.
2. Fill in the fields for the proxy servers, and check that there are crosses to
the left of the text fields. It is possible to use the same proxy server in all
the entries.
3. Click on the OK button.
Electronic mail
Opera supports sending electronic mail. Before you can use this facility from within
Opera, you must set up your name, the machine you will use for mail (mail server),
and your own mail address. The address must conform to the following format:
name@address.country
ie. SMTP conformant. The name of your mail server can be obtained from your network
support personnel or your Internet supplier. If you already use a mail program it
can be easier to just access that from within Opera. You do this by specifiying
the program instead of your name, mail server and address.
This is how to set up your mail preferences:
1. Choose Mail... from the Preferences menu.
2. Fill in the fields for name, mail address and mail server, or enter the program
name to use your own mail program.
3. Click on the OK button.
Discussion groups (News)
It is possible to use Opera to read so-called discussion or news groups. To be able
to do this you must tell Opera where to find these groups, ie. the name of a News
server. You should ask your network support personnel or your Internet supplier
for the name.
This is how to set up a News server:
1. Choose News groups... from the Preferences menu.
2. Type in the name of a News server.
3. Click on the OK button.
