A new 2024 DOS demo called Pits has achieved native multicore processing and Full HD graphics in pure DOS without relying on external drivers. Since the legacy operating system lacks built-in multithreading, developers accomplished this by running standard DOS on one CPU core while executing custom code on additional cores. This workaround coordinates the cores via shared memory and requires programmers to manually implement synchronization, effectively writing a micro-kernel to manage the complex cross-core execution.
