- Introduction
- ------------
-
- Thank you for installing SETI@home. With your help and the
- help of hundreds of thousands of other computer users like
- you, we increase the odds of detecting signs of intelligent
- life elsewhere in the universe. This Help File explains how
- SETI@home works, how to alter its settings, or how to remove
- it from your computer.
-
- SETI@home actually consists of two parts: an "application"
- and a "screensaver". The application does all the work: it
- downloads blocks of data through the Internet, performs the
- number crunching on that data (looking for orderly patterns
- that might be artificial), returns the results, and gets
- another block of data. The application is represented by a
- green radio telescope icon in the System Tray (normally at
- the lower right of your screen). You can open the applica-
- tion window by double-clicking on this icon.
-
- The screensaver program runs when you haven't used your key-
- board or mouse for a while. It displays color pictures
- showing the data analysis process. Normally the application
- processes data only when the screensaver is running.
- Optionally, you can have the application process data all
- the time.
-
- ------------------------------------------
- Logging in to SETI@home
- ------------------------------------------
-
- To use SETI@home you must create an "account" on the
- SETI@home server. Your account is identified by your email
- address. This lets us notify you in case you discover ET.
-
- If you run SETI@home on several computers, they can all run
- under the same account.
-
- When you install SETI@home, you are asked whether you want
- to create a new account or use an existing account. The
- account is verified or created on our server at UC Berkeley,
- and SETI@home will run under this account indefinitely. If
- you want to switch to a different account, bring up the
- application window, open the Settings menu, and select
- Change/Create login. You will be shown the name of the
- current account, and you can elect to switch to another
- existing account or create a new account.
-
- To switch to an existing account, you just type in the email
- address. If you create a new account, you will be asked for
-
- 1. Name or nickname (handle)
- 2. Email address
- 3. Country
- 4. Postal code
- 5. Whether your computer is at school, work, or home
-
- We will not give this information out to anyone. We use it
- to get statistical information such as how many people in
- country X are participating in SETI@home, how many users are
- at school, etc. This information is on display at our Web
- site, http://setiathome.ssl.berkeley.edu.
-
- If you check the option to display your email address, your
- email address might be shown on our web site if your screen
- saver finds something interesting, or if you earn some other
- mention, such as by crunching more data than any other user.
- The default for this setting is to NOT provide your email
- address. It's up to you. You can also decide whether to
- have your name appear on the web site.
-
- Windows lets you declare names and passwords for different
- users on the same machine. However, changing your Windows
- login doesn't affect SETI@home. If you want to change your
- SETI@home login, you must use the Settings menu.
-
-
- -----------
- Preferences
- -----------
-
- SETI@home lets you express your preferences for when it does
- data analysis, and when it makes network connections. You
- are asked for your choices when you install SETI@home, but
- you can change them later if you like. To do so, bring up
- the application window, open the Settings menu, and select
- Preferences.
-
- There are three sets of preferences:
-
-
- Data Analysis: either
-
- - Data Analysis happens only when the screen saver is active
- or application window is open, or
-
- - Data Analysis always runs
-
- If you select the first option, SETI@home won't use any of
- your computer's processing power or memory when you're doing
- your normal work. If you select the second option,
- SETI@home will analyze data all the time. this uses about
- 15 MB of RAM and requires processing power, so we recommend
- this only if your computer is fast and has lots of RAM. If
- you try this setting and notice sluggish performance of
- other programs, turn it off.
-
-
- Network Connection: either
-
- - Ask me before connecting to the Internet, or
-
- - Connect automatically whenever needed
-
- You can choose whether SETI@home should ask your permission
- before setting up an Internet connection to the SETI@home
- server. A connection to the SETI@home server is only neces-
- sary when it's time to retrieve a new block of data. On a
- typical Pentium-class computer, this will happen every one
- or two days. Therefore, connection is not going to occur
- very frequently, but still you may want to have the screen
- saver alert you before doing so.
-
- If you connect through a modem and your computer shares the
- phone line with voice calls or a FAX machine, you'll prob-
- ably want SETI@home to ask your permission before connecting
- (otherwise it might try to dial while you are in a phone
- conversation, which can be annoying). Choose the first
- option in this case. The flashing SETI@home icon will alert
- you when SETI@home wants to set up a connection.
-
- If you are connected to the Internet through a local area
- network (LAN) or have a modem with a dedicated phone line,
- choose the second option (connect automatically). This
- allows SETI@home to be more productive. If you choose this,
- don't be shocked when the modem suddenly begins to dial the
- phone, seemingly out of nowhere. SETI@home probably just
- needs more data to analyze.
-
- SETI@home will connect to the Internet using the connection
- that is specified as the "default" connection in your Inter-
- net Settings. To set or check this setting, open the
- Start/Settings/Control Panel/Internet/Connection. If you
- use a modem to connect to the Internet, you probably already
- have a dialup networking connection (DUN connection) there.
- If you have multiple ISPs (Internet Service Providers), the
- DUN connection specified as the "default" connection is the
- one that will be used. Use the "Set as default" check box
- to select which ISP will be used if SETI@home is going to
- make an automatic connection. If you have trouble with your
- Windows auto-dialing setup, just make the connection manu-
- ally when SETI@home gives you the option to "Connect Now".
-
-
- Proxy:
-
- This lets you specify the name and port number of your HTTP
- proxy. An HTTP proxy is a network security barrier used by
- many businesses to protect their computers. Your network
- administrator can give you the info. If you don't know what
- an HTTP proxy server is, you probably don't have one - just
- leave the "direct connect" button checked.
-
- -----------------
- The Blinking Icon
- -----------------
-
- Sometimes you will notice that the SETI@home icon is blink-
- ing. This means that your attention is needed. Double click
- on the icon for instructions. There are several possibili-
- ties:
-
- - SETI@home needs to connect to the Internet, and is waiting
- for your permission to do so. If you do not have your com-
- puter set to dial automatically, you will have to dial manu-
- ally (by running your Internet Dial-up connection for your
- ISP) before telling SETI@home to go ahead.
-
- - There is a new version of SETI@home that you can download
- from our web site (http://setiathome.ssl.berkeley.edu).
-
- - SETI@home has encountered an error that you can fix. For
- example, you might be out of disk space. Delete some files,
- then click on OK to have SETI@home continue.
-
- - SETI@home has encountered an internal error. In some
- cases you may be able to fix things by quitting the
- SETI@home application (click the button in the upper right
- corner of the application window) and starting it again. If
- the same error occurs repeatedly, please report it to use
- via our web site (http://setiathome.ssl.berkeley.edu; go to
- "Software Download and Help").

- ------------------
- Removing SETI@home
- ------------------
-
- Tired of looking for ET? Want to go back to flying toasters?
- Is SETI@home causing problems, and want to turn it off?
- Here are the three options you have:
-
- - If you want to temporarily disable SETI@home until the
- next time you start up, right click on the SETI@home icon
- and select Exit. It will run again the next time you boot
- up or the SETI@home screensaver runs. To run it manually,
- click on Start / Programs / SETI@home.
-
- - To select another screen saver. Click Start / Settings /
- Control Panel / Display / Screen Saver. Choose a different
- screen saver. If you have selected "Data analysis always
- runs" in your Preferences, SETI@home will continue to work
- in the background; otherwise it will run only when you bring
- up the application window.
-
- - To remove SETI@home from your computer and hard disk,
- click Start / Settings / Control Panel. Then run Add/Remove
- Programs, select SETI@home, and click the Add/Remove... but-
- ton.

- Frequently Asked Questions (FAQ)
- --------------------------------
-
- Q: How do I bring up the SETI@home application window?
- A: Find the SETI@home icon in the Windows "system tray" and
- double-click on it. The system tray is normally in the
- lower right-hand corner of the screen. The SETI@home icon
- looks like a green radio telescope dish. You can also
- right-click on the icon and select "Maximize".
-
- Q: Where is the SETI@home icon? I don't see it in the sys-
- tem tray.
- A: You may have exited from the SETI@home application by
- accident. You can run it again by selecting Programs /
- SETI@home from the Start menu.
-
- Q: I don't see SETI@home in the Programs menu.
- A: Install SETI@home again; download first if needed (from
- http://setiathome.ssl.berkeley.edu).
-
- Q: How do I set my default screen saver?
- A: In the Control Panel, double click Display to bring up
- the Display Properties dialog. Select the Screen Saver tab.
- There you will see a list of available screen savers from
- which to select. Note: SETI@home makes itself the default
- screen saver when it runs for the first time after installa-
- tion.
-
- Q: Can I use Windows screen saver password protection with
- SETI@home?
- A: Yes.
-
- Q: How do I completely get rid of SETI@home?
- A: In the Control Panel, go to the Add/Remove Programs dia-
- log, and select SETI@home. Or you can select "Remove
- SETI@home" in the Start/Programs/SETI@home menu.
-
- Q: My PC has lots of RAM and a fast processor. Can I have
- SETI@home run all of the time?
- A: Yes. Bring up the SETI@home application window, and in
- the Preferences dialog, select the checkbox "Data analysis
- always runs."
-
- Q: I'm running on a laptop and the installer hangs after I
- choose the directory into which SETI@home is to be
- installed. How do I fix this?
- A: On a few laptops, the InstallShield setup program causes
- a search for the floppy drive (drive A:), which takes a
- minute or two if the drive is not connected. Wait a bit, and
- the installer should recover.
-
- Q: I've just downloaded a new work unit and the connection
- to my Internet service provider has not been terminated.
- Does SETI@home hang up the phone?
- A: No. Windows automatically terminates your connection
- after a period of inactivity. You can set the length of this
- period in your Internet settings in the Control Panel. Your
- ISP may also close the connection after a number of minutes.
-
- Q: I'm running the screen saver: the left and right parts of
- the display appear to be cut off. Why?
- A: You are probably running your system with a display reso-
- lution of 640x480. We now allow SETI@home to run in that
- resolution; however, you will not be able to view the entire
- display. We recommend display settings of at least 800x600.
- You can change the settings for your computer in the Con-
- trolPanel / Display dialog.
-
- Q: I'm running on a dual processor Windows NT system, and
- the graphics look "weird". How do I fix this?
- A: You can fix the SETI@home behaviour by setting your sys-
- tem to force SETI@home use 1 processor.
-
- Q: I'm running on Windows 2000 Beta 3, and the screen saver
- does not launch the client. Why?
- A: We believe there is a bug in this beta version of the OS.
- You can manually launch the client from the start menu. If
- you "preview" the screen saver from the Display properties
- dialog, it will also launch the client.
