Little brother has a difficult problem: How to install the DOS 6.22 system? And how to install UCDOS? My system is WIN98, I heard that it contains DOS 7.0, I wonder if UCDOS can run under MS-DOS? If it can, then how to install UCDOS?

——————Little brother is very anxious, looking forward to the guidance of the great experts, I will be very grateful!

UCDOS7 can run under DOS7. You can directly double-click INSTALL in WINDOWS to install UCDOS7. After installation, create a shortcut on the desktop. The command line is: command /k c:\ucdos\ucdos.bat. Finally, modify the properties of this shortcut, click Program - Advanced - Disable program detection of WINDOWS. Then you can start UCDOS with this shortcut and use EXIT to return to WINDOWS.

Installing DOS622 requires that your C drive is no larger than 2G and in FAT16 format. Most of the time, you need to clear the system and repartition, so it's better to use DOS7.

It can be said that basically all programs that can run under MS-DOS 6.x can run under MS-DOS 7.x (except for a very small number of programs that depend on disk formats), but programs that can run under MS-DOS 7.x may not necessarily execute correctly under MS-DOS 6.x. After all, in most cases, the higher the version, the better. The DOS built-in in Win98 is MS-DOS 7.1, and installing UCDOS 7 directly under pure DOS will not have problems.
