Running MS-DOS 6.22 on VirtualBox using .img files allows you to resurrect retro software, play classic DOS games, or simply experience the OS that powered the early PC revolution. This guide walks you through the entire process, ensuring your MS-DOS 6.22 setup works perfectly in a modern VirtualBox environment. Prerequisites
: Create a new Virtual Hard Disk (VDI). Choose a fixed size of 2.00 GB or less. MS-DOS 6.22 uses the FAT16 file system, which cannot address partitions larger than 2 GB. 2. Add a Virtual Floppy Controller ms dos 622 img files works with virtual box top

With the VM configured correctly, follow this exact sequence. This is the “works with virtual box top” method that avoids boot failures. SET BLASTER=A220 I7 D1 H5 T4 Running MS-DOS 6
Insert the first floppy image into the virtual drive. In the Storage settings, click the empty Floppy Device slot, click the disk icon to "Choose a disk file," and navigate to your 144UPG1.IMG file. Start the virtual machine.
Now, type FDISK and press Enter. FDISK is the DOS utility for managing partitions. Since this is a new virtual disk, it will ask if you want to enable large disk support. Select "Yes" to use the FAT16 file system. Create a primary DOS partition, accept the default size (which uses the whole disk), and then make it active. After creating the partition, you must restart the virtual machine for the changes to take effect. You can do this by pressing (Host Key + R) to reset. Choose a fixed size of 2
