Same board.

Asus PVI-486SP3? Great, thank you! Okay, I'll get an NV18 or NV17 chip then, pretty good odds either will work. Really hard to find PCI versions, so might take a while. I'll report back.

Can someone please elaborate on why any PCI card, even a GT 610, wouldn't boot in a 486 board? Is the issue with the newer PCI spec that isn't supported by the chipset? Do we know exactly what's causing an issue with newer cards, so we can determine the fastest possible card for each chipset w/o necessarily having to test everything.

Particularly curious was that a Geforce2 would function properly but a TNT2 M64 wouldn't even show a power-on screen.

I'm pretty sure some video BIOSes want Pentium or newer instructions, but it isn't something I have ever tried to verify.

The search for a GeForce4 MX PCI continues, so far it's all $100+ that I've found... 🙁 Has anyone tried a 5200 PCI in a SiS 496/497, preferably with a POD? I can get that for $20.

Indeed... I wish there was a way to figure out the reason. Did you ever try the TNT2 in a SiS 496/497 by the way? I only see results for UMC on the front page.

Quadro 4 NVS 100 works at least on some 486 boards. But GeForce 4 MX is semi-useless on 486. Drivers are too new to support OpenGL games, so stuff like GLQuake is out of the question.

I must be some kind of standard: the anonymous gangbanger of the 21st century.

I used to have my MB-8433UUD system setup with a POD-100 and a GF2MX. It ran opengl pretty well considering it is a socket 3 board.

Nope, it's a socket 3. For some people, that's all that matters. For others, the CPU must be 486 architecture. For some, a 486 can't have PCI. Some only want period correct, etc... Whatever floats you boat man.

I spent some time last winter with the PCI cards 486-PCI motherboards that I had available to see if there was a clear tell for what would work.

Cards: S3 Trio64V+ (1996) Tseng 4000w32p (1996) , Matrox Mystique PCI (1997) , Permedia 2 (1998), MX4000 (2003), Radeon 9250 (2004), Radeon x1300 (2005)
Mobos: FIC 486 VIP (Via82C505) & Gateway BAT4IP3 (420EX) Both 1994. Gateway has a power plug for extra PCI power.

The stuff from the 90's would work with the 486's, the stuff from the 00's didn't stop the computers from booting, but wouldn't generate a VGA signal.

Certain cards will not initialize on unsupported motherboards at boot up. I had that happen to a board which was ATX micronics socket 7 based on 430HX. I purchased later one, intel made motherboard based on 43oTX chipset and can initialize all the cards I throw at it.

Intel's own AN430HX works with everything. Any ATX board should work too in theory, because they support PCI 3.3v, unlike most AT boards.

Its irreverent in this case. "3.3V" and "5V" PCI cards refers to SIGNALING voltage, not the actual power required to run the card. Signaling voltage is what the address and data lines use to represent 0s and 1s on the bus. All Baby-AT PCI motherboards have an onboard VRM to provide the necessary 3.3V power supply rails to power cards themselves (ATX boards get it from the power supply). That same VRM likely provides power to the CPU socket as well.

Just to clarify, PCI cards come in three varieties, 5V (notch towards the rear of the slot), 3.3V (notch towards the front of the slot/back of the computer), and universal with two notches. Almost all conventional PCI slots are 5V signaling. You really only see 3.3V signaling only slots on PCI-X compatible boards since that standard dictated it fro m the start. The only widespread application of a 3.3V conventional PCI was found in the Blue&White Power Mac G3/Yikes G4, which used such a slot for its dedicated 66Mhz PCI ATI video card.

Early Pentium motherboards usually don't have it (including first gen 430HX b0ards). And 486 PCI boards never had it.

That same VRM likely provides power to the CPU socket as well.

AFAIK - no. AT boards use separate VRM for that or additional power connector for PCI.

Then sounds like poorly done BIOS hampered mine when I had Micronics HX ATX motherboard out checking out PCI video cards.

I'm still skeptical, I can't find evidence of anyone using a 486 or POD with a card that has a full MPEG-2 decoder, actually installing drivers successfully and playing DVDs, maybe I'm the only one who's ever wanted to do that 🤣.

Hi!

Hello. Sorry, I know I'm late, but I got to play DVD smoothly on my 486. This machine doesn't work now because of the f*ck*ng Dallas, it doesn't save the BIOS values so can't boot from hard disk.

The configuration is:

- AMD 5x85-P75@160Mhz (it does little stops at 133Mhz when playing DVD)
- 256MB RAM Kingston, 4x64MB 60ns
- 256KB L2 cache
- Biostar MB-8433UUD-A Ver.2 motherboard
- Creative Blaster S3 Savage-4 32MB PCI
- Mpeg-2 RealMagic Hollywood Plus DVD Playback Card PCI
- Creative Sound Blaster AWE 64 Gold 4MB ISA
- USB 2.0 Adaptec AUA-5100B PCI
- ISA Lan 10Mbps NE2000
- Samsung SFD-321B Rev.S1 floppy drive 3'5" 1'44MB
- 4'3GB + 2'1GB HDDs
- CD-RW 24x10x40
- DVD 16x LG
