Create Bootable MS-DOS 6.22 CD in Windows 10

When you have to update the BIOS of an older system, sometimes you have to boot into the old MS-DOS or FreeDOS and then execute the update program. This problem no longer exists in the newer UEFI based motherboards. We have already posted about how you can create a bootable FreeDOS CD for this purpose. But you can also create a bootable MS-DOS CD if you want a quicker solution. You won’t have to go through various steps as we posted about the FreeDOS CD. Here is how:

  1. Download and install ISO Workshop in your PC from http://www.glorylogic.com/iso-workshop.html.
  2. Click on the Make ISO button to create a new ISO image.MS-DOS 6.22 Bootable CD
  3. In the window that opens, choose Bootable and then select the Dos622.img file that comes with ISO Workshop. Click OK to proceed.MS-DOS 6.22 Bootable CD
  4. Now you can add any DOS programs like the BIOS update program to the ISO image by dragging and dropping these files in the Make ISO window. Change the disk type to CD 650 MB. Click Save to proceed and save the ISO image somewhere on your hard drive.MS-DOS 6.22 Bootable CD
  5. You can use ISO Maker to burn this ISO image to a blank CD with your CD/DVD writer.

When you boot using this CD, it will go straight into DOS. But since Microsoft DOS version 6.22 is a very old operating system, some of the newer DOS based programs (that were developed on a FreeDOS system) might not work or fail to run properly using this bootable CD.

In any case, if you are not able to use your programs through this bootable CD, then you can use the bootable FreeDOS CD that can be created using the steps we have mentioned in our previous post – how to create FreeDOS CD to update the BIOS on older systems.
