Why is Dioscuri equipped with FreeDOS instead of MS-DOS?
As most operating systems and applications are proprietary, Dioscuri is not allowed to be distributed with such software. Instead, Dioscuri is distributed with the open source operating system FreeDOS, which is quite similar to MS-DOS. However, during tests Dioscuri was able to successfully run MS-DOS versions 4.2.0 and 5.0.0.
