SvarDOS: DR-DOS is Reborn as an Open Source OS

SvarDOS, a compact open-source operating system derived from DR-DOS, has switched to using the EDRDOS kernel, marking a shift from its FreeDOS distribution roots. The change allows the operating system to fit on a single 1.4MB floppy disk while offering a network-capable package manager that can fetch from a repository of over 400 packages.

Unlike its rival FreeDOS, SvarDOS can run Microsoft Windows 3.1 natively, though the capability currently requires additional configuration. The system maintains compatibility with legacy DOS applications while providing modern features like FAT32 support and network connectivity.
