Under DOS, using the duse program lets me use USB devices, but then the problem comes up? 1. My system is DOS 8.0. If duse.exe is not loaded in config.sys, Tianhui Chinese 3.2 can start normally. But if duse.exe is loaded in config.sys, Tianhui will not start, and it says: program too big to fit in memory. Why? 2. Also, after loading duse.exe in config.sys, as soon as the mouse driver starts, the machine hangs. What exactly is going on? If I don't load the duse program, Tianhui can start, and the mouse driver can also load. I don't know why??? Note: duse is version 4.9 Please help!!!!!

You need to optimize memory. The reason is that conventional memory is too small.

To put it plainly, after loading duse, your conventional memory becomes too small, so many programs can no longer stay resident in memory, especially programs like ucdos and Tianhui that need to stay resident and take up a lot of memory. Possible solutions to try: Load himem.sys and emm386.exe in config.sys, then use devicehigh when loading duse, and see whether duse can be loaded into upper memory (that way it won't take up conventional memory). Also, when starting Tianhui, you can try loading it with lh. In short, DOS is a very backward system. Most programs can only use 640KB of conventional memory, while memory beyond 1M is not very easy for many programs to use. In short, it's troublesome.
