No tv out

Hi,
I have a Nvidia GeForce FX 5200 graphic card in a media center pc where
the only display is the tv set connected to the s-video out.

The problem is that when I turn on the pc nothing is displayed on the tv
until the operating system loads the graphic card drivers. So I can't see
the bios screen, I can't enter the bios setup, I can't boot with a DOS
floppy, I can't see the text console in Linux and anything before the
high-level drivers are loaded...

I've tried adding one 75 ohm resistor in parallel whith the luminance out
and another one to the chrominance out, just to be sure that the output
were correctly terminated (and perhaps the tv-out recognized) but the
problem remains.

I don't want to add a vga monitor every time I need to see bios and/or
console messages.

Is there a way to enable tv-out for all the video modes, just as the vga
out normally does? Perhaps changing the videocard bios?

Thanks for answering.

Since the video *does* show up once the Windows drivers are loaded,
there isn't anything wrong with your connection. It seems you need the
drivers before output is done to the video-out.

Looks like that's what you'll have to do.
Some cards are made with dual outputs that *are* enabled all the time.
Other times you can find an input other than standard video to hook to
the video card, especially on HDTV monitors.

S-video seems a crappy way to connect.
Better (only slightly though) than RCA video connections.

I doubt it.

the driver for the TV out does not load until windows loads

I have a solution for you, but it sucks :-)

Connect a scan converter to the VGA port.

There are cheaper ones. This is the first one I could find
on Amazon, that had customer reviews. Kworld is the bottom of
the barrel, so it won't get much cheaper than this.
