Did you try to update (or downgrade ?) the BIOS and look if that can fix this problem ?

Yes, it's on the list of the things I tried in the first post. I upgraded to the latest BIOS available for this board.

It's the Intel "Orlando" NV430VX

If I'm not mistaken, it was only made for OEMs with minor defferences, for example mine doesn't have the on-board sound card.

Can you lower the FSB ?

Voodoo 1 Cards are not stable if FSB is higher than 66 Mhz

I could, but it's Pentium 1 anyway (66MHz) and the same card does work on another P1. I'll try it just for the sake of it.

Have you tried changing the PCI port of the Voodoo Card or even switching the 2D passthrough and Voodoo card around? Sometimes PCI cards work in some slots and not others - the topmost slot was what I used for Voodoo cards in some builds IIRC because the others could prove problematic. It could be an IRQ conflict of some type; I would try going into BIOS and disabling Automatic PCI IRQ assignations and manually assign IRQs only to ports I actually use and see if that helps..

Also, have you tried to see if it works with one of the EARLIER BIOS versions? It could be a PCIset issue that presented itself in a later BIOS and went undetected as Voodoo cards were not a thing back then..

PCI uses "INTs", not IRQs.

Just nitpicking.. 😉

Sorry, I stand corrected, it might be conflicting INTs 🙁

Nah, that's okay; IRQ is commonly used as an abbreviation for "interrupt" (-request).
Really just wanted to mention that link. It tells about the (physical) differences about ISA/PCI.
On PCI, not all slots are handled equally. On the computer side, INTs are mapped to IRQs.
And since the compatibility issue seems to be more hardware (bus) related, I wanted to point that out. 😀

These cards do not use an irq adress.

I don't know a solution to this problem, it's just strange that windows works fine. Maybe another bios version but otherwise i don't know what i would try.

Perhaps other memory, psu or harddisk as these things can cause strange behaviour.

Now that's something I haven't tried. I'm not sure though how I can, there doesn't seem to exist an earlier BIOS available online.

About changing slots and components, unfortunately those are all done and listed in the first post. Maybe another direction would be to start thinking what Windows might be overriding/changing that makes the card work.

The first thing that comes to mind is that Windows is a PnP OS and your PCI configuration may be set to PnP (Auto) and DOS can't handle that well; have you tried setting your ISA/PCI slot configurations manually in BIOS?

Sadly yes, that one was really probable and I was certain that playing with these would fix it.
