There are 4 machines running UCDOS 98 normally on XP. But one machine (Dell Optiplex 740) has a UCDOS crash when running, and when running the core program knl.com alone, it has a screen flicker. It has been unsolved all the time. Downloading the official website graphics card driver can't solve it. I don't know why? The online methods have basically been used, and there's no way to solve it. Asking netizens for help, thanks!
