SLI setup not recognized by A8n-deluxe

[reznikvova]

Hi,
I recently switched out my faulty A8n; Dlx for a new one. All other hardware remained the same:
Raid 0 Hd's
Amd 4000+
2gb Ocz
2x Msi 6800 128mb's

The problem is that I cannot enable SLI in the ADV. settings menu. The only option available is " Add another card for super performance gain" Before I used to have a checkbox wher I could enable the SLI,

The bus speed is stated as 8x? Split, so it must see the other card?
In 3dM05 is claims total AGP memory is 256mb?

But still performance in any game shows sli is not on.

I have tried the EZ selector card in various positions, and variosu bios settings.
I have used driver cleaner to erase and re-install drivers.
Both video cards work, and neither the EZ card, or plu that connects two 6800 is at fault.

Any Ideas? Hopefully not a faulty Mobo?! Again!

Maybe I must format+ new install? (running Xp home sp2)

Thanks in advance!,
Vova

Some more:
When the Ez plug is set "Dual video card" I am able to start Comp with a single card.
When I set it to single, with single card, there is VGA error in POST.

When two cards are inserted in "single" I get blank screen in Blue slot, but video in black (2nd) slot?

This is all very strange. Any ideas?
