Because I recently need to use the extremely ancient DOS 6.22 for learning assembly language and operating system principles. When I simulate MS-DOS 6.22 with Virtual PC 2004, the CPU usage rate is as high as 60%-80% (my system is P4-2.8G, memory 1G). May I ask if there are any ways to reduce the CPU usage rate? Please, seniors must help, thank you in advance : )

To learn assembly language and operating system principles, you don't necessarily have to use such old DOS versions. Using the new DOS 7.10 is completely okay. If you want to reduce the CPU usage, you can try the IDLE program, or install a pure DOS in a real machine and give it a try.

DOS 7 is too complicated for me. And the source code I have is for DOS 6. For the convenience of learning, I chose DOS 6. I have set up a disk array on my machine, and I'm afraid that directly installing DOS will cause errors that I can't control... I searched "IDLE" on GOOGLE, and the result is a software called RAM IDLE Pro. Brother站长, are you talking about this thing?

Load the additional component ISO of VPC, then enter the \dos folder in DOS, and you will see IDLE.

When I CD to the virtual drive, I can see idle.com, but I can't run it or copy it to the virtual hard disk. Both copy and xcopy don't work, and it prompts that the file idle.com is not found. What should I do?

There is no power management under DOS; it keeps waiting for you to enter commands. I also encountered such a problem in the past. Just add a power program for management. What an old post! I don't know if anyone will see the answer now. Hehe

Can you explain the operation steps in detail? Thank you in advance!
