China DOS Union

I installed the XP system. After installing UCDOS and CCDOS on the C drive, after starting the UCDOS and CCDOS executable files, the screen was first black. I initially thought I had entered the DOS system, but after a few seconds, the interface jumped back to the WinXP interface. What's the matter with this? How can I correctly enter CCDOS or UCDOS? Thank you

Under XP, it is impossible to start Chinese platforms such as UCDOS, CCDOS, or Tianhui, because these Chinese platforms all need to directly write to the screen (that is, directly access hardware), and the kernel of XP does not allow programs to do so. Therefore, you can only refer to the top - sticky post "Summary of Various Methods for Playing DOS under Windows XP" for the method of reinstalling a pure DOS environment on the machine, install a pure DOS environment on the machine, and then start UCDOS, CCDOS, etc. in these environments.

Thanks

Then how to start UCDOS under Windows 2000...
