As we move further into 2025, two things are happening: 1️⃣ (Windows 11 24H2, Server 2025, and modern Linux kernels) are tightening driver signature enforcement. 2️⃣ Legacy MCS hardware still runs critical infrastructure.

Before hunting for a driver disk, check if your MCS device has a PnP ID (starts with PCI\VEN_ ). Use that to find modern compatible drivers via Windows Update Catalog.
