Howto install MSDOS & drivers and Autodesk 3DStudio 4 on a VM using VirtualBox

In this short video I'll show you how to install MSDOS 6.22 with CDROM support and mouse drivers, and then 3DStudio 4 on a virtual machine in VirtualBox. The end result will be a virtual machine that can not only be used to work in 3DS but it will also allow you to play classic DOS games.
To easily access the files that you want to use in DOS I'll start with creating an ISO file using ImgBurn. Place any games you want to play on the ISO as well for easy access.
I left out the narration because the audio was really bad in the recording and I couldn't be bother to do a new recording.
