Multicore suppport for DOS is real – partly
Summary
A Vogons forum discussion about multicore support for DOS, exploring two main approaches: a native SMP DOS OS built from DOS 4.0 sources and a modern SMP host with DOS running inside VM guests via a DOS personality layer. The thread enumerates extensive architectural requirements, challenges (ACPI, APIC, memory management, SMP synchronization), and discusses the feasibility and trade-offs of each path, including references to related projects and prior work.
