If VirtualBox frustrates you, 86Box or PCem offer cycle-accurate emulation (including Sound Blaster 16), but they are heavier. For most users, VirtualBox with converted IMG files remains the “top” balance of convenience and compatibility.

Installing on VirtualBox using .img (floppy disk image) files is a highly reliable and the most authentic method for emulating this classic OS. Users typically use a set of three images (Disk 1, 2, and 3) to complete a standard installation. Compatibility & Requirements

If Disk 2 doesn't work, ensure you are swapping it only when the DOS setup specifically asks for it.

Before using your .IMG files, you must prepare a specific virtual machine (VM) container within the Oracle VM VirtualBox application. Name it something clear like "MS-DOS 6.22".
