Hi,

So I've got a Vortex86DX3 system - a VDX3-ETX-74IX-V2 ETX module with an IP412 carrier board.

So far I've gotten everything up and running in windows 98SE - OrpheusII LT, USB 2.0, Ethernet, SATA - the only thing left to get working is the GPU - A GeforceFX 5500 PCI.
I know for sure that the Geforce FX 5500 PCI works in windows 98SE, I have 2 of these cards now and it's working in my other 2 systems.

I get this glitch when I try to load the driver.

The attachment 1000000105.jpg is no longer available

I get a similar behavior in XP except it's commas and it will eventually go to a black screen and stops there.

I'm guessing that it has something to do with the PCIe-to-PCI bridge chip that it's on.

any ideas?
I'm willing to try using PCIset.exe to change configuration registers on the PCI bridge if anyone has experience in working with that?

You'll need to find a Linux distro that is i586-compatible (if you really want to put in the effort with setting up a KVM virtual machine with a raw image via libvirt and using dd to copy the raw image to a physical drive, Gentoo will do the job), but current versions of Mesa still support the Geforce FX and will work on i486, provided the VBIOS is 486-compatible.

At the very least, it did work when I tried exactly two years ago with my PCI Geforce FX 5200.

That said, the PCI-e to PCI adapter I have doesn't work on 486 mobos, and was incredibly flaky with various (Super) Socket 7 chipsets when using a Radeon X300 SE as a test, in that built-in and PCI IDE cards were barely functional. The one chipset I didn't try was a 430TX.

I've been able to boot into Xubuntu 12.04 using nomodeset if that counts? It won't boot without nomodeset.

From 12.10 onwards they started using PAE which doesn't seem to be supported by the Vortex86DX3.

The PCIe-to-PCI bridge chip is on my ETX model seems to be an it8892e chip.
I don't have any documentation on it though, so I wouldn't know how to configure it. I'm willing to try anything though

Has anyone else got any systems with the IT8892E PCIe bridge chip? and if so do you have any trouble running GPUs on it?

I've found the datasheet for the IT8892E chip in theretroweb.

https://theretroweb.com/chip/documentation/it … b9907145577.pdf

Can anyone give me some advice on using PCISET to configure it? I would like to get my GeforceFX 5500 PCI working over it if possible.
