Totally forgot about this thread, apologies to everyone. Hello galanopu, That sounds great! I'll drop a PM later to arrange shipping. Would you also want/be able to test PCIe -> PCI and PCIe - > AGP adapters? Filename PCIe_PCI_3.resized-1024x368.png File size 582.01 KiB Views 12115 views

1.No. The notch has nothing to do with it, that is related only to the IO signals voltage. 3.3V keyed slots supply two 3.3V rails, one for IO (low current) and another one for powering stuff. 5V keyed slots supply 5V for IO, and 3.3V for powering stuff. 2. You would have to disable the VRM. And …

If they're legit ICs (not fakes or broken pulls) they should work. If shipping takes a long time and you're impatient, you could at least temporarily use an EEPROM from a donor card. Some TNT2 cards have this exact EEPROM, like https://www.ebay.com/itm/InsideTNC-Dream-nVidia-Riva-TNT2-Model-M64-32MB …

From my limited testing (a couple of motherboards, and mostly 3dfx cards) it worked just fine. If anyone if willing to properly test it (preferably from the EU, it's easier for me to ship) I can send an adapter (as in trade it for testing, I'll add a blank PCI bracket as well :) ). As for price, if …

If it's a broken address trace between the VSA and the EEPROM, an external programmer would not help. The EEPROM content will be good, but the VSA won't read it properly. Highly doubt that is the case though, most likely faulty EEPROM.

You're right, that is a 100nF cap. A good replacement is 100nF 25V 0603 X7R dielectric.

You should be able to put a blank EEPROM and just flash it like usual, without the need of an external programmer.

Thanks! Quite possible. Most existing AGP to PCI adapters are pretty crappy, for example some have one or more of the following: -linear regulators, which get stupidly hot -no filtered AGP VIO, might cause instability -no level shifters, plugging a card like a V4/5 into an older PCI slot will kill …

For adding DVI to a VSA card, there is no need for an FPGA. A TMDS encoder, such as TFP410, will do the trick. It might not be register compatible with the SiI164 used on the original DVI V4/V5 cards, but that can be easily fixed. The databook for the VSA100 is available online, it contains most of …

Updated the beginning of the thread with component values for another Voodoo 2 reference design based board, specifically a Creative CT6670. This, with what I posted before, should cover most V2 cards out there.

C9 on your card is a 3.3-4.7uF, minimum 6.3V, 1206 cap. You're also missing C48 (top side, bottom right corner), this is a 1nF 25V 0603 cap.

Hi, I used an LCR bridge. In my case, the measured values were closer to 4.7uF than 3.3uF. Some variation is normal, some manufacturers modified the reference design a bit (the card shown in the first post has polarity markings for the 1206 caps and uses ceramic caps, some manufacturers used …

Already looked at the pictures. The pins can be loose and look fine. You can only tell when poking them.
Re: Faulty v2?

Most likely the ICs are OK. Gently poke all TMU/FBI pins and see if any of them move. Then check for broken traces, corrosion, missing/chipped passives.
Re: Voodoo 2 component map
Posted on 2020-04-27, 23:02
Besides missing/broken SMDs and bent FBI/TMU pins, another thing that should be checked on any faulty V2 card is loose FBI/TMU pins. Try gently poking each pin and see if any of them moves. Also, check out the post made by Tronix here: https://www.vogons.org/viewtopic.php?t=64338 The debug utility …
Re: Voodoo 2 component map

@gex85 No problem! But before replacing the cap I'd recommend checking the card for other damage, I don't see how a missing C128 would cause this behavior. C128 is used for TMU0 RAM VCC decoupling, the card should be detected without it.
