Ms Dos 622 Img Files Works With Virtual Box Top 🆒

Legal notice: MS-DOS 6.22 is copyrighted by Microsoft but considered abandonware. For educational/review purposes, here are reputable archives (ensure you own a license if required in your jurisdiction):

Verify integrity: Use WinMD5Free to check IMG file sizes (each should be exactly 1,474,560 bytes). Corrupt IMGs cause “Sector not found” errors.

| Problem | Likely Cause | Fix | |---------|--------------|-----| | Invalid system disk after boot from IMG | IMG file missing boot sector | Rebuild IMG using SYS A: from a working DOS VM | | Setup hangs at "Starting MS-DOS" | PAE/NX enabled in VM settings | Disable PAE/NX in System → Processor | | Setup cannot find Disk 2 | Floppy controller timing | Swap IMG faster. Use Host key + F to refresh floppy detection | | Not enough memory to install | Too much RAM (over 64MB) | Reduce VM RAM to 16MB. DOS 6.22 doesn't need more | | No fixed disks present | Hard disk controller wrong | Use PIIX3 IDE, not SATA. Also ensure disk is not >528MB (old BIOS limit) |

Create a blank IMG file (using WinImage), mount it as a second floppy drive. Use it to move files between your modern PC and DOS VM.

Title: Just confirmed: MS-DOS 6.22 .img files work flawlessly with VirtualBox (Quick Guide)

I see a lot of people asking how to install DOS on modern hardware without physical floppies. I can confirm that standard MS-DOS 6.22 .img files work "out of the box" with the latest version of VirtualBox.

No need for complex conversions if you are just booting from floppy.

How I did it:

Note: You will have to unmount/mount the next disk image when the setup asks for Disk 2, but it works like a charm.

Screenshot attached. Happy computing! 💾

Based on community forums (VirtualBox.org, Vogons), here are the top fixes ranked by effectiveness:

| Problem | Top Solution | |---------|---------------| | “FATAL: No bootable medium” | Use Method 1 (convert IMG to hard disk). Floppy booting is unreliable. | | Setup asks for Disk 2 but hangs | During the prompt, press Host Key + F (usually Right Ctrl+F) to bring up the VirtualBox floppy menu before pressing Enter. | | General Protection Fault after install | Reduce RAM to 16 MB. DOS 6.22 struggles above 32 MB. | | Mouse doesn’t work in DOS apps | Use PS/2 Mouse emulation. In VM settings → USB → disable USB controller. Use PS/2 mouse under System → Pointing Device. | | Sound Blaster not detected | VirtualBox lacks SB16 emulation. Use PC Speaker or install a third-party driver like VDMSound via a network share. | Legal notice: MS-DOS 6

Add an IDE CD-ROM drive in storage settings. Use MSCDEX.EXE and OAKCDROM.SYS from the DOS 6.22 supplemental disks.

After formatting, setup continues. You’ll see: "Setup will now install MS-DOS 6.22 on drive C:"

Follow prompts, install to default directory C:\DOS.
