Modern hypervisors like VirtualBox technically support NT 3.1, but you will struggle. VirtualBox requires you to disable ACPI and set the chipset to PIIX3. Many users report a "critical boot failure" with modern VMs. The best advice:
Modern hardware often struggles with NT 3.1's legacy drivers. For the best experience, virtualization or emulation is recommended. 1. Virtual Machine (VM) Configuration
If you are ready to start your retro-computing journey, head over to a trusted archive, configure your hardware profile with conservative memory limits, and enjoy a flawless trip down tech memory lane.
