Putting a modern NVMe SSD drive on a vintage computer PCI bus

• Use an M.2 PCIe 3.0 SSD with an M.2‑to‑PCIe AIC to fit vintage PCI slots. • Connect the AIC to a PCIe‑to‑PCI adapter, bridging modern and legacy hardware. • PCIe and PCI are physically different but logically compatible, no special drivers needed. • The setup delivers near‑modern SSD speeds on old motherboards, reviving legacy systems. • Successfully booted Windows NT and Windows 2000 from the NVMe drive. • Technique also works for retro graphics cards, expanding vintage PC capabilities.
