She walked over to the old machine and popped the side panel. "Kai, do you have the image?"
For true authenticity, nothing beats running MS‑DOS 6.22 on real iron. Here is what you need to know.

To make your CD-ROM drive work continuously, copy a generic IDE CD-ROM driver (such as OAKCDROM.SYS or VIDE-CDD.SYS ) to C:\DOS and update your boot files. Edit C:\CONFIG.SYS
Making an MS-DOS 6.22 ISO work requires a small shift in mindset back to the days of manual memory management, strict partition limits, and command-line precision. By keeping your virtual hard disks under 2 GB, allocating minimal RAM, and configuring your high-memory drivers correctly, you can create a blazing-fast, perfectly authentic environment to explore the golden age of PC computing.

Keep the virtual hard drive small (under 2 GB) to match the limitations of the FAT16 file system used by DOS 6.22.
After rebooting, the system still cannot read the C: drive until it is formatted with the FAT16 structure: HIMEM is testing extended memory
Create a virtual hard disk (VHD or VDI) fixed at 2 GB or less . MS-DOS 6.22 uses the FAT16 file system, which has a hard structural limit of 2.0 GB per partition.
The "ISO" files available today are community-created images. These images typically take the floppy disk contents and compile them into a bootable CD structure (ISO 9660). This allows modern users to install DOS much faster than swapping virtual floppy disks and enables the inclusion of bonus utilities, drivers, and tools that would not fit on a single floppy.
Kai slumped into his chair. "I don't believe it. MS-DOS 6.22 saved the grid."
