I don't think it's possible.

Yes, Quantum3D has the Mercury 'brick' which has 4 cards, each with 2 V2's on it but as far as I know, those extras are only used for anti-aliasing purposes.

It wasn't until the VSA-100 that more than 2 chips could be used for performance and I think even that generation of SLI was limited to 4, again Q3D's AAlchemy 8xxx card using the extra 4 for anti-aliasing.

And how are you going to connect more than 2 cards with that cable? You could make a single cable with  4 connectors, something like you can see on SCSI cables, but then you'll need the cards installed in a specific order in slots and a driver that knows exactly which card is the "first" card, the second card, etc.

Then wht do you want the cards to no? Normally 2 V2 cards will render a scene "line by line", so I assume you'll want 4 V2 cards to render lines 1,2,3,4, then again 5,6,7,8, etc.

In theory it's not even very hard, but in practice it might be
"a little" harder.

Here you can find some sourcecode, including some V2 sourcecode for Linux driver.

But I'll ask again: what do you expect from a 4 way SLI setup? Better framerate in games? Better quality? (antialiasing) Higher resolution?

Connecting 4 V2 will not be a problem, don't worry about that FDD cable, instead try to answer yourself the questions from above.

It's cool when you think: hey, I have 4 V2s in SLI. OK, great, but what can you do with them (something that 2 V2 cannot do).

yeah, my 1st reason would also be AA, without framrate drops, bit like the AAlchemy cards, only with 4 voodoo2 cards
