So my Quicksilver system finally showed up today (A deal long in the making!) and when I opened it up found a surprise. The machine is setup with a 90-4440 AGPTV board as was expected but for a 2D device there was a Ventana 50 Voodoo Rush!

Doing some digging around I found these links-

If I had to guess I think what happened was Quantum3D took some spare Ventana boards they had lying around, reflashed them for 2D only operation and sold them included with arcade hardware.

Here is a blurb from the Quantum3D web archive link above.

"There is another accelerator which also uses the ProMotion AT25 Alliance Semiconductor chipset. However, it is not a daughter board rather a normal PCI board. The accelerator is called MGV-PCI.

The MGV Rush populated board is similar to the MGV-PCI but has the 3D addition which is not used. It may some times be confused with Ventana board which has TV Out and 3D chips populating the board in a Voodoo Rush configuration. However, the MGV Rush board only uses the Alliance chip for 2D display and the 3D portion will not function.

The Ventana Rush may look similar to the MGV Rush populated board but has the Chrontel chipset used for TV Out. The accelerator has 3D chips populating the board in a Voodoo Rush configuration.  In addition, the accelerator may have "Ventana" silk screened onto the board near the Quantum3D logo. This board was never sold for public use nor was it released as a product."

Below is pictures of the bios on boot up and picture of both cards.




The board does function under 3D somewhat when the Rush single plane drivers are loaded. Turok worked fine but both GLQuake and Quake II had some texture image issues with the MGV-PCI. Might be fixed with a reflash to the Ventana 50 bios but I have no plans to do so.

yeah another very exclusive way to use good old 3dfx hw 

nice baby gary gratulations 

Very nice, congratulations. This is a very exclusive system

I know Obi Wan, that's why I used the ' ' around non-3D.

And what has your Vero got to do with G's card? ???

According to babelfish, Vero is Italian for True
True 3D, original name

Correct, it has no TV out and the bios that states "MGV-PCI"

It does work fine in Turok, but not Quake I/II & I did not test any other programs.

Another issue I ran into when loading the reference Rush drivers- The refresh rate goes out of the monitors range and the only way to get it back down is to crank up the screen resolution to 1024 x 768.

Even them it acts odd, but 2D works normal when the MGV 2D drivers are loaded. The other Ventana Rush board does not do this so I think Quantum3D did go out of their way to try and "disable" the card for use with 3D or reference drivers.

Yes, I'm well aware of that and as soon as my 100SB-4440 arrives one of the first things I will do is see if a Shade module fits the Rush board.

I have been waiting a long time to find one so that could be tested.

Let us know your test results eh Gary!

This is something quite special! 8)
