I am a computer science and engg student. I am trying to do a project named "Multitasking under MS-DOS". It is not true multitasking( neither co-operative nor pre-emptive) just task switching.
If any one wants to change the task, he/she will press an hot key, then they can get the shell to change the task. For that i need to know what are all the things that is to be saved about DOS's current system state. I am planning to store the current system state in hard disk (as a file).
Please kindly help me quickly, because I have only 2 more months to finish the project.
Help me please.....
