Hi everyone, I figured that i want to make a really simple operating system based on DOS. I am thinking using the MS-DOS startup disk and then creating a program and dragging it to the disk and running it from the startup disk... Though when i try and run the program while using the MS-DOS startup disk i get THIS PROGRAM CANNOT BE RUN IN DOS MODE. Do i have to use a special compiler. Right now i am using VS2008. BTW ITS JUST A LITTLE SIMPLE HELLO WORLD PROGRAM!! WRITTENT IN ALL C++.
