Time for necroposting. I've tested some cards which worked on Intel TC430HX board:
All Voodoo AGP cards (obviously).
All S3 AGP cards based on original Virge design, including Trio3D/2x. No tested yet Savage 3D or Savage 4, so no idea if they'll work.
All original Rage Pro cards, including Rage Pro Turbo AGP.
Matrox Millenium II AGP cards.
Cirrus Logic Laguna 3D AGP aka CL-5465 (works very slow though).
Cards which did't worked:
3DLabs Permedia 2 AGP - can't boot OS with driver.
Nvidia TNT&TNT2 - can boot OS, but driver is not loaded.
Nvidia GeForce series - can't boot OS with driver.
ATI Rage LT Pro AGP and newer - can boot OS, but driver is not loaded.
Cards which potentially could work:
Nvidia Riva 128 & Riva 128 ZX
SIS 6326 series
Matrox G100
Overall this adapter works well with Intel chipsets, judging from Socket 7/Slot 1 era, but everything else is hit or miss.
I must be some kind of standard: the anonymous gangbanger of the 21st century.
