Installation, Upgrade, Applications tested with etc at the end.

Rev 1.0.0.1
Mar 05, 1998
1. Modified INF file to remove erroneous "Device not working properly"
   message in the Device Manager after install. You don't need to restart
   Windows after installation.
2. Modified INF file to default to 320x240 16bpp input mode if settings
   not set previously.
3. Modified Video Format dialog box to remove the unsupported FULL (640x480).

Rev 1.0.0.0

1. Limited sizes to 320x240. Earlier bigger sizes showed up but were not
   supported.
2. Reports dropped frames by using the estimated framerate. Makes the AVI file
   more synchronous even if no sound is present.
3. Fixed MSDOS Full Screen and dynamic mode change (3DMaze screen saver)
   hang problem when AVI Capture driver is active.
4. Removed misleading display with no resources when installing.

Rev 0.0.0.3
Dec 5, 1997
1. Modified PCVideo.DLL to work with both SMBus and GPIO
2. Modified PCVideo.DLL to return error if VPM is using the Video Port.

Rev 0.0.0.2
Nov 11, 1997
Initial release

To Install:
1. Go to the Control Panel from the Start menu (CTRL-ESC, Settings, Control
   Panel), select Add New Hardware, Next, No (to windows searching for New
   Hardware, since the decoder is on the GPIO pins, Windows will not
   detect it), Sound Video and Game Controllers, Have Disk.
   SMBus systems (Gateway 2000) do not need special GPIO settings.
   The default settings are for GPIO 0 and 1. If your system has different
   settings, edit the PCVideo.INI file to reflect the new settings for
   GPIO_SDA and GPIO_SCL

To upgrade:
1. First remove the device from the Control Panel, System, Device Manager,
   Sound Video and Game Controller, Chips and Technologies Video Capture.
   Then install it again like described above.

This release has the following limitations
1. It does not use a VSync Interrupt due to lack of this in the Hardware
2. The frame rate is limited to 5 frames per second (320x240 8bpp, P150)
3. Tearing may be visible, especially if the capture is in 16/24bpp modes.
4. This conflicts with the VPM and only one can be active at a time,
   either the VPM or the AVI Capture driver. The AVI Capture driver detects
   if the video port is in use and returns an error.
5. Fails a couple of tests of the Microsoft WHQL Video Tests in 320x240.
   No errors if reduce size.
6. Overwrites display memory momentarily in some apps when starting. 
7. Does not support dynamic mode switching in Windows. Usually see corruption
   or loss of overlay.
8. Supports formats upto 320x240 only.

This release has been tested with the following applications and works
reasonably well. (~12fps in 24bpp 160x120, and ~29fps in 8bpp 160x120, P266)
1. Microsoft NetMeeting 2.1 (cound see and transmit video)
2. CU-SeeMe 3.1 (could see video. Network problems occured when tried connection)
3. VideoWave from MGISoft (could see, record and playback video and frames and
   create AVI files)
4. Stefra (could see, record and playback video and frames and create AVI files)
5. Intel Internet Videophone with Proshare Trial Applet 2.1 (could initialize video
    Network problems prevented further testing)
6. VDOPhone 3.0
7. Microsoft VidCap.
8. Microsoft WHQL Video tests
