README.TXT For REALmagic Netstream 1(TM) Version 2.35 - 4/16/98
===============================================================

Congratulations on your purchase of the REALmagic Netstream 1
multimedia playback controller.  This file contains important 
information not available at the time the manual was printed.  
Please take time to read through it for the latest updates.

NOTE : 
====
- Some boards will carry the former signature name of the board 
"REALmagic Ultra II", and MPGDEV.SYS will show at booting time 
a message that this is an unknown card. This should NOT be a 
source of confusion.
- This release fix a problem in the REALmagic DOS driver that 
could not load with the TVOUT equals to 1 or 2 in FMPDRV.INI.
- This release has the correct version of the Windows TV switch
program.
- The Uninstall program under Win 95 just removes the 
SYSTEM.INI entries and asks the user to remove the board 
from Device Manager.

1 - SOFTWARE INSTALLATION 
    =====================

NOTE :

a - After installation, the resources used by the board such as the I/O 
address and the IRQ number will be shown in a blue panel at booting time.
They can also be seen in the FMPDRV.INI file in the REALmagic directory
(usually REALMAGC).

   IMPORTANT :

        In case of a PnP motherboard, if you wish to override the values
        of the IRQ channel or/and I/O address by switching to a manual 
        mode assignment, you can edit the file FMPDRV.INI as follows : 

         [REALmagic]
         PlugPlay=0     to force the use of the following values

         [NoPlugPlay]
         Interrupt=     channel required
         Port=          I/O address required

        The above applies only in the DOS and Win 3.x environments. For 
        a Win 95 environment, the board will use the resources assigned
        by the system and shown in the Device Manager.         



b - Calls to "MpegVideo", the MPC standard Windows driver name for MPEG
decoders is supported.


    a - NOTES ON SETUP    Windows 3.x
        ==============

        i - Improved Error Handling
            -----------------------

It is possible that with some hardware configurations, the I/O address,
and IRQ scanning done by the SETUP program will cause the
system to crash (in almost all cases, this is due to poor resource 
management of another component).  The SETUP program maintains a status 
file in the root directory of your boot drive.  If the system crashes 
during the scanning, SETUP will make a note in the status file.  When 
your system reboots, re-run SETUP that will automatically continue 
scanning your system, skipping the IRQ or I/O address test that had 
caused the system to crash previously.  This process may repeat before
all of the offending causes are eliminated.  If there are no errors,
the status file is automatically deleted upon the completion of SETUP.

Note:  It is possible that if you use a disk caching program other
       than the Microsoft SMARTDRV (version 4.0 or later), the
       status file will not be updated if the system crashes.
       This is most likely to occur for a delayed write type of
       disk cache program.  In such instances, disable the disk
       write caching program in the CONFIG.SYS or AUTOEXEC.BAT 
       file before running SETUP again.


        ii - Command Line Options
             --------------------
You can manually disable the scanning of the I/O address, IRQ, and
DMA channels.  Modify the SETUP command line to look as follows :

    SETUP  /NOTEST  

Also, if SETUP still crashes while trying to identify the board,
you can force the board ID by adding the parameter /MPEG
as follows

    SETUP  /MPEG

You can combine the parameters as follows :

    SETUP  /NOTEST  /MPEG



    b - PnP INSTALLATION   for  Windows 95
        ----------------------------------

After the hardware installation do the following :

1 - Boot your system. 
2 - After the Windows 95 logo display, the system will recognize that a
    new board was installed (Plug-N-Play feature of the REALmagic 
    Netstream 1 board). You will get the window "New Hardware Found" 
    with the REALmagic Netstream 1 signature.  
3 - Choose the option "Driver from disk provided by hardware manufacturer".
4 - Click OK.
5 - A new window "Install from Disk" will display. Insert the REALmagic 
    Netstream 1 diskette in your floppy drive. Make sure the text box
    specifies the correct drive specifier ( e.g. A:\).  Click OK.
6 - The system will start copying all the software to the C:\REALMAGC 
    directory. Then it will return to the desktop.
7 - Click on Start. Choose Run.  Type A:\SETRM.EXE. Click OK.
8 - Reboot the system (Start, Shut Down, Restart System). 
     


        i - CHANGING A RESOURCE (for Advanced Users)  in Windows 95
            -------------------

If you wish to change a resource (I/O address or/and IRQ number) assigned
by the Plug N Play feature of Win 95, do the following :

1- Start System from the the Control Panel group.
2- Choose Device Manager and double-click on "Sound, video, and game 
   controllers".
3- Double-click on "Sigma Designs REALmagic Netstream 1".
4- Select the tab "Resources".
5- Double-click on the required resource. Click "Change Settings".
6- Modify the settings to the required value. Make sure there is NO conflict
   specified in the Conflict Information box. Click OK.
7- Edit the file C:\REALMAGC\FMPDRV.INI as follows :
     - under the [REALMAGIC] section the line Port= for the new I/O Address
     - under the [MPEG] section the line Interrupt= for the new IRQ.
8- Reboot.


2 - BORDER ADJUSTMENT AND COLOR CALIBRATION
    =======================================
NOTE :  You must set the Border Adjustment and Color Calibration settings
        to finalize the installation.  You need to set the Border Adjustment
	and Color Calibration only once for each display settings
	(resolution, number of colors, and refresh rate) under Windows, and
	run Border Adjustment only one time in the DOS mode.
	This utility can be called also from the RM Mixer utility.

Windows:
-------
1- Start Border Adjust program in the REALmagic group.
2- Use the H-POS and V-POS buttons to align the top left corner of the 
   black and magenta rectangles, then use the H-SIZE buttons to resize 
   the black rectangle to cover exactly the magenta area. This should 
   work for the majority of the VGA boards available.

   IMPORTANT NOTE :  For the following rare cases :-
   a -If the black area height is HALF the magenta area height, click the 
   button "NI" (non-interlaced) and then "EXIT". Restart "Border Adjust".
   b -If the black area height is DOUBLE the magenta area height, click the 
   button "I" (interlaced) and then "EXIT". Restart "Border Adjust".
   It is recommended NOT to use the buttons "NI" and "I" other than the
   above indicated conditions. 

3- Click the Save button to save the settings.
4- If you observe jittering at the right or left edge on the aligned 
   black box, click on the Horizontal Stability "+" and "-" buttons
   until you get the smoothest sides among the 16 values.
5- Next, click the Auto button to automatically calibrate the color for 
   your VGA card. Color bars will be displayed on the screen followed
   by a vertical white line flashing in the middle of a black screen. 
   When the Border Adjust program is redisplayed, calibration is complete.
   - If you are using the SVGA drivers of Windows 3.x, add the following 
     line in the [VGA] section of the file FMPDRV.INI in the REALMAGC 
     directory:
           SVGA = 1
   (If you select manual calibration, then follow the instructions 
   provided on the screen to adjust the colors in three steps.)
6- Click the Done button.


DOS:
---
1- At the DOS prompt (in Real Mode MS-DOS FOR Windows 95), type 
   DOSCALIB and press <Enter>.
2- Repeat step 2 above  - aligning the black and magenta borders -
   (and 4 if necessary - smoothing the jittering) and press Exit. 
   This procedure will repeat THREE times for text and graphics modes.


3 - REALmagic MIXER
    ===============

Besides the volume adjustment for the MPEG audio signal, the RM Mixer
has got three additional TV set-like faders for the following :

	- Fader "B" for Brightness Control
	- Fader "C" for Contrast   Control
	- Fader "S" for Saturation Control

You can adjust these faders while playing an MPEG file for a better
control of your setting. 

There is also a button for "Border Adjust and Calibration". Just click 
it to activate this utility.


4 - RUNNING DOS TITLES   (on a Windows 95 system)
    ==================

The way DOS works has slightly changed under Windows 95. In order 
to optimize performance of DOS MPEG titles, please run the titles in
the real mode MS-DOS:

1-  Select "Shut Down" from the Taskbar (after quitting Windows 
    applications).
2-  Select "Restart the computer in MS-DOS mode".
3-  At the DOS prompt after reboot, enter the command for the title,
    such as :

         C:\>D:
         D:\>DOSTITLE

4-  To start Windows after exiting from the title, type :

        c:\>EXIT  <Enter> 


5   VGA-TV SWITCHING
    ================

You can run this program by double-clicking the icon to switch the 
MPEG output to a TV monitor. You can use an NTSC or a PAL TV set.

In Windows, if you are playing back an MPEG file encoded from a PAL
origin (288 pixels high) on an NTSC TV set (240 pixels high), you 
can select to have a 1:1 scale (dropping the extra pixels evenly
from top and bottom producing an exact image of the original) or
to have a "down scale" that will scale down the 288 pixel rows to
240 pixel rows).  

Notice that High-Res pictures, in CD-ROMs encoded in VideoCD 2.0
mode, will always appear on the VGA monitor ( the CD Station is 
capable to play this format).

Please make sure to close the program after switching.

In DOS, you can run the program TV.EXE and choose between TV-NTSC, 
TV-PAL, or VGA.  It will work always in the down-scale mode.


6 - ISSUES with PROTECTED MODE  32 bit  CDROM DRIVERS:                     
    ==================================================

If you play VideoCD's in the Protected Mode of the CD-ROM driver
(32 bits) and the CD-ROM drive is installed as a slave drive
on its own controller (if it is an IDE drive), the playback will
suffer some breaking.  

Solution : Install the CD-ROM drive as a MASTER drive on a
           secondary IDE controller, use the Real Mode, or down-
	   load from the MicroSoft web site the file IOSUPD.EXE to
	   update the version of IOS.VXD to 4.00.953.

NOTE : CDi movies (Green Book standard) can be played only in
       Real Mode.

	Real Mode is activated by removing the CD-ROM controller
        from the Device Manager, adding the CD-ROM driver in the
	CONFIG.SYS, and re-activating the MSCDEX.EXE line that
	was used before Windows 95 installation.


7 - SPECIAL FOR SOFTWARE DEVELOPERS OF MPEG TITLES
    ==============================================
Version 2.21 & 2.3x of REALmagic drivers are using a new algorithm 
to reach the best accuracy in Frame Seeking.  This might not work 
for titles developed using earlier versions of REALmagic drivers.
To force the driver to use the old algorithm, modify or add the
following line in the [MCI] section of the FMPDRV.INI in 
the REALMAGC directory to be :
         
                   SeekAccurate=False
