Help: AGP Radeon 9100 disables old PCI vid card on Soyo Dragon K7V+...Why?

[kwo]

Greetings all!

Here's the scoop:

Had a Matrox G400max 32mb dualhead enabled video card. LOVED IT!

Found out that my two upcoming must-have games(Homeworld 2, NOFL 2) do NOT support it. BUMMER!

Bought: Xtasy radeon 9100 64mb AGP. (from TD, $30 AR, *IF* I get the rebate back)

Don't have a digital monitor, so can't use DVI out on the RADEON 9100 as secondary.

Stole OLD Diamond Stealth 2000XL 2mb PCI card from daughter's computer (gave her my Matrox...sniff!).
This Diamond card works fine *alone* in either daughter's or my computer.

BUT...when AGP radeon is present, Windows XP device manager shows the S3 Virge (Diamond Stealth) DISABLED and no secondary monitor.

If I set INIT Display to PCI (instead of AGP), then both cards coexist..but I don't like having the Stealth as the primary card, and Homeworld2 Won't run (at least the demo, the AGP must be primary)

Checked forum, but didn't see anything relevant. Checked SOYO website, and found that PCI/VGA SNOOP must be enabled. It IS enabled, but that does not solve problem as the S3 Virge(Diamond Stealth) is STILL disabled.
(Note: also happens with an old S3 Trio32 PCI card as well)

So, WHY does the presence of the RADEON 9100 disable the PCI card in the device manager??

Any ideas? Thoughts/comments would be appreciated!
(see below for setup)

THANKS!

Ran

a little bumpage, if you don't mind...I'd like to find a solution, if one is known...

Those old S3 graphics chips cannot live in multi-VGA environments. Get a DVI-VGA adapter and run the 2nd head off the Radeon as well.

Hello Peter!

Thanks for replying. I would *love* to do that..but the Radeon only has a DVD-D connector....so I can't use a converter. As both of my monitors are analog, and I can't afford to replace one with a digital-in LCD...I'm stuck with trying to use another vid. card.
I *am* glad you responded, though...as that now explains why neither of these cards will function. it looks like a newer PCI card should work fine....I hope...

Ah. So you have one of those "special" 8500 cards ...

Yes it would - unless the mainboard's BIOS screws something up in that regard. But that is rarely seen these days.

 

[kwo]

I gather by your use of the word "special", that you don't consider this to be a very good card? Ah well, for $30 (AR & probably after yanking TD's collar all over) I couldn't pass it up....

There are a handful of 8500 cards that aren't dual head capable although the chip is, and although these cards have two connectors. Design silliness, somewhat.
