Time to necropost... I finally got to finishing the new revision of the adapter, I have uploaded it here: http://sdz-mods.com/index.php/2020/06/22/pci-to-agp-adapter/ Editable schematic & board file, PDF schematic, BOM, and GERBER files. Hi SDZ, Could you share the files for the PCIe x4 to PCI …

Thank you, but that one cannot do DMA. I wonder if its possible to write a TSR that captures DMA operations for these new boards though, there is one from MSi too. Some older PCI sound cards did have some emulation software/tsr attached. Are you sure about DMA on this board? I had assumed that …

I inquiried Fintek for datasheets. In the a meantime, a question: Can this adapter be passed to a VM? Not related to this adapter, but if you require a motherboard with ISA passthrough capabilities, DFI has a Skylake motherboard with ISA slots, designed to work with KVM/QEMU via a proprietary …

I see the latest iteration is keyed for 5v only. Is there not going to be a universal 3.3v/5v version, like the earlier prototypes?

Also pretty sure changing refresh rates in DOS on the FX 3500 will work with it's stock bios. 7900GS-PCIE-256MB.7z Awesome, many thanks for that …

Well I guess I can do that, if it comes to it. Maybe the Quadro cards still have fully working VBE 3.0, in which case I probably wouldn't bother converting it either. But when did this move beyond simple BIOS reflashing? Was that not sufficient for GF4 & GF5 series cards still?

Brand is Inno3D 256MB PCI-Express. https://www.cdrinfo.com/d7/content/inno3d-7900gs?page=1 https://www.cnet.com/products/inno3d-geforce-7900-gs-graphics-card-gf-7900-gs-256-mb-series/ Not had any problems with this card running any Dos games so far and it has VBE3. ATI/AMD apparently never made …

I have been using a GF 7900GS @100hz in pure DOS since 2007 with UniRefresh. Dos svga vesa games at default @60hz is screen flicker headache inducing hell, especially on larger crts. DVI will output 60-72hz but could also be changed if panel supports it eg 144hz. This is just with the factory …

I don't know what motherboard you intend to use, but bear in mind the bridged AGP cards will start artifacting (geometry, not just pixels) when used with some motherboard chipsets. I definitely ran into this with 7600GS AGP on a VIA 694X board. Interesting thing though is that it only happened with …

for NVidia video adapters one must dis-assemble the vBIOS code to determine the location of the various tables which determine the VGA and VESA modes and 'dot-clock' values to change refresh rates. Once you program the CRTC registers directly, you can do almost anything in DOS... However, if you …

Did you try this GF7 HEX edit yourself? If i do this, would UniRefresh work again with GF7 series cards? I'm just entering a rabbit hole, I didn't know of this tools' existence before. Can i use any arbitrary refresh rate with it as long as my monitor supports it?

Reading around the forums, it seems this 60hz problem has started as early as the GF4 series cards? Could I use the BIOS values of a GF2 or GF3 to do this HEX edit on a GF7? Bit out of my depth here... Re: UniRefresh no longer works on nVidia's latest

One other thing i'd like to try is getting a Vortex2 card working in win2k Not very useful in Win 2k/XP - only basic DirectSound3D is supported. I found a post by ZanQuance that suggest he had A3D fully working under Win2k, that's how this idea came to be. Or is wavetracing just impossible with wmd …

The geforce FX series, which I do own, handles DOS like a champ and so does the geforce 6 series according this matrix: Yes, VBE 3.0. May have a bug with unchangeable 60 Hz refresh rate in VESA modes, which was reported here on vogons. Fixable via HEX editing BIOS. Excellent information! I presume …

thx guys I couldn't find any threads discussing the GF7 in depth, and I searched for quite a while. I want to use one of the cards with PCIe-AGP bridge chip, if i can get ahold of one. Somewhat odd follow up questions - has anyone ever tried using a GF7 under pure DOS? Does it support VESA modes, …

A few questions about the Geforce 7 series, if i may: What is compatibility like for Geforce 7 cards with DX7 & DX8 games? Do all GF7 cards support Table Fog? (Any specific drivers I have to look out for?) 16-bit dithering is supported with these cards? (I've seen claims to both ends...)

how well does the voodoo1 scale with a faster cpu?
