A: Windows 10’s 2020 update blocked legacy drivers with weak signing. You must disable driver signature enforcement or use DDU + NimeZ.

There are no new, official AMD drivers for the Radeon HD 4890 on Windows 10 64-bit.
AMD stopped driver support for the entire Terascale 2 (and earlier) architecture (HD 2000–HD 6000 series) years ago. The last drivers that work with the HD 4890 are Catalyst 15.7.1 (July 2015) — but even those are not fully compatible with modern Windows 10 builds.
A: Yes, but only with NimeZ custom drivers. Official Catalyst 15.7.1 may fail to install or cause system instability.
Fix: The HD 4890 does not support UEFI GOP. Force your motherboard to use Legacy/CSM boot mode instead of UEFI. If your PC is UEFI-only (modern laptops), the HD 4890 will never work.
