From my testing, the Aureal Vortex 2 is more compatible with DOS games on the 775dual-vsta, but it doesn't sound as good as a real OPL3 or ESFM.

If Aureal Vortex 2 you own has waveblaster, you can cheap with MIDI module like dreamblaster 😉

hi
got a 4coredual sata build here - works fine with hd3850 and a gtx570 and 4gb ram win7 32bit and xp etc - so ive got my hands on a gtx590 but it doesnt post on the asrock board - but i does display/post on a std intel pcie 3 mobo - so the card works but not in either my asrock board or a gigabyte combo board = not posting with the PCIe x4 slot . isnt there something in the bios that needs to be disabled for these Fermi nvidia cards to work ie they dont like ?????

Its not about the card generation, its something about the specific card.
I have several 5xx and 6xx cards which post in the board - and i have also personally seen a few one NOT posting in it.
Try a different video bios.

As mentioned in first post in this thread :

I've also tested dual GPU cards, the HD4870x2 and the GTX295, none works. So far it seems single GPU cards only.

There is no dual GPU that will work on this board (aside from 7900 GX2/7950 GX2, which got specific official BIOS patch to make it work) - not sure why anyone would thought a GTX 590/HD 6990 will when older DX10 dual GPUs didn't ?

If anyone is trying to use 3dfx cards in this motherboard, its a big no-no.

-Voodoo Rush hangs at boot, likely causing an unresolvable irq conflcit with the disk controller. The computer freezes when detecting the hard disk, if the rush is in the computer. I tried all possible PCI ports without success.
-Voodoo3 refused to boot in any of the PCI ports.
-Voodoo2 gets detected, and can be installed. The last beta driver from 3dfx cant work. The last final driver works, but 8 from 10 game simply crashes with it. Even glide games crash. Some games have missing geometry. Croc and F22 lightning 3 runs in glide mode without an issues. Drakan starts, but crashes if start to play and press esc to enter the menu when returning the game. (ok this is the fault of something else, because it does this bug with other graphics cards as well) F1 from 1997 works. The rest of the games i tried (about 30 of them), crash at start, causing the computer to hardlock.

I use this mb with a 12mb voodoo2 and I don't have any problems. I think unfortunately you have an issue somewhere else.

I cant think anything else, because if i use other graphics cards, i don't have issues with those. In the past days, i have used a 3dlabs permedia 2 pci, and everything was fine with that.
The mentioned voodoo cards also work flawlessly in my socket7 system.

Maybe its partially something with the CPU, which older games and drivers dont like. (q9300)
The pci card boot issues are however the fault of the motherboard.

-I am verifying the RadeonHD 6950 (2gb VRAM version) is working in the 775dual-vsta.
-The kepler based nVidia 730 (GDDR5) is NOT working in the motherboard.
-nVidia 1060 is not working in the motherboard. Numlock works, but no boot, and no picture.
