Are u enable legacy or csm support in uefi? Try set video priority to pci first, not pcie or internal.
I know not as Haswell+ machines, but my z68 with 3770 ivy bridge work good with all pci cards, except Via USB controller.

Don't have the "pci first" option, but I disabled the internal VGA completely: without a PCI card, even if the monitor cable is attached to the built-in VGA, it beeps the no-VGA sequence.
The three cards - ATI Rage, S3 ViRGE, Hercules Terminator 64 - work ok with the current settings. And even with the two non-working ones, the MoBo doesn't beep the no-VGA sequence - so they are recognised, but don't work. It looks to me like there is really a compatibility issue.

But your experience with ivy bridge is indeed interesting. Have you tried the older S3 cards - the 86c764 or 86c864 ones?

I use s3 trio 64+. It's work good. U check ur s3 with other machines, they work, or possible have hardware problems?

Yeah, as you can see in the table the trio64 works both on a 440BX and nForce PCs, so it's definitely working.
So, you used in your test a Trio64V+ card which is more modern. The Trio64V+ uses a 86c765 chip, which does work on my Haswell PC too. Do you have a non V+ Trio64 card to test?

yes, sorry... its 765.
I will look in my collection, may be i have two more non-765 s3... 😀

It's an interesting idea, but I'm not sure I'd bother with it. VTd works, but it really isn't the same as running on a real PC. Cards which are designed for passthrough (some Quadro) work fine, but need the specific drivers to operate properly. Others, such as a PCI-e Matrox G550, only work if they're the primary graphics card, otherwise the BIOS doesn't initialise and it's detected but doesn't work.. Many other cards, although they work fine with a bare metal os, simply do not work in VTd - graphics cards really are pretty much the worst case scenario for virtualisation.

Xen/KVM support VGA with VBE 2, or QXL if you're using Spice. They're probably not much worse than an old S3 card..

Well, it seems that with PCI cards the passthough is simpler than PCI-e. All the cards I have which work with the C220 motherboard also work in guest. The trick here to find the ones which work on the host. As for QXL - it is indeed a good adapter, but the OS I'm targeting - AIX - doesn't support it.

I have an old 4-port 8 drive Fastrak EIDE controller in my machine, which I need to take out one of these days as there is no support for Windows 2016, only Windows XP and below.

If it works with VT-d motherboards/CPUs, it should be possible to pass it through to a guest OS. But you'll still need the Windows XP or below running as a guest. Not sure if such a setup makes a lot of sense though. It may be easier to get a compatible IDE controller.

I'm now using a Turtle Beach Santa Cruz on a Windows 98SE VM running on the VMware ESXi 5.0 hypervisor. The motherboard is an Asrock X58 Extreme. Earlier I also tested a Yamaha YMF744. Both cards works, but FM synth and Sound Blaster emulation doesn't.

AMD/ATI PCIe cards usually works on ESXi, but there isn't any way to disable the emulated VGA so it always ends up as a secondary adpter. I have used AMD cards in Ubuntu and Windows 7 VM's. Using open source drivers in Ubuntu required me to modify the kernel so the BIOS for the card could be loaded off the hard drive.

I start to think the PCIe->PCI Bridge may be the problem. My board has the ITE 8892E bridge.

Exactly. To expand upon your point... Native PCI support was ditched, post Ivy Bridge and Panther Point chipsets. All PCI from Haswell on is purely bridged over PCIe, which introduces numerous compatibility issues with older cards.

Ordered an Asmedia 1083 PCIe-> PCI converter. Let's see if it works any better than ITE 8892E.

I have been wanting to put together an All-In-One Retro gaming machine by using a product called UnRAID and passing through diffrent video adapters to diffrent VMs. Most people I have asked think that passing through older GPUs may not work like some would like it to, but as far as I can tell no one has tried it with older cards yet. If anyone does anything like this before I get to it. I'd love to see it.

S3-Trio64V+ pass through works with qemu just fine. Actually all the PCI cards which work in my host (see the first post) can be passed through, but I tested the Trio64V+ most extensively. Unfortunately it doesn't quite cut it for my use case: I need a Vision864 compatible card. That's not a problem of passing the card through though, it's the card itself.

Also, PCI cards for passthrough are usually an incredibly bad idea because there's no isolation between them - *all* PCI cards have to be passed through to the same VM. PCI-e cards may or may not be isolated from each other depending on their root port and the chipset.

I don't see how it makes it an incredibly bad idea. Say, I have just one PCI card to pass through, but if I had more they would have been retro too (after all they are PCI), so giving them to the guest OS does perfectly make sense. YMMV though.

It's fine provided you only want to pass all the PCI cards through to one VM. Typically VM boxes want to pass through to separate VMs, or only pass through one card out of a selection.
