I'm not quite sure what you are trying to do, but I do know that many video boards with composite (TV) out will copy the signal just so long as the video mode is supported. On my ATI boards (I have a 3d ProTurbo and an Xpert@play - both have TV out) will send video to the TV even during bootup. Of course, this may vary from vendor to vendor, but I remember my old Canopus Pure3D also would copy the signal to it's TV out during bootup as well - so it didn't require a supported OS either. Given that, I believe most vendors just put scan converters on their boards; there isn't any separate video subsystem. As far as I know, all you have to do is ensure that the board is being driven properly, and you will get TV output. Now, as for having multiple video boards - that is a separate issue. I'm not familiar enough with FreeBSD to know if it has, or needs, multiple video board support for X to work with multiple boards. If you are worried, though, you might consider attaching a dumb terminal (or terminal emulator on a laptop) to a serial port and use that as your administrative console. I have an otherwise worthless Compaq 468 laptop that runs a copy of IVT (a freeware DOS VT220 emulator) for "emergencies" that kill or crash X.

We need to show on a closed networks of TV sets some announcements, presentations and animations. The application will be written in Java but what I need to know is: 1) is there any card with TV output supported by FreeBSD; 2) Since the FreeBSd machine is going to be used as a server and the announcements will be placed by clients on the network, is there any way to automatically start the graphical environment and run the java application on a specific video card without affecting the main console video card. Usually there is going to be no console monitor connected but we may require to connect one for maintance reasons. Thats why I want to use a secondary video card for the announcments and also I don't want that someone that might play "accintentaly" with the keyboard to kill the application or move windows arround. any coments; nn To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
