China DOS Union

I downloaded the full installation version of DOS 7.1 from the forum. I achieved the function of installing DOS after installing XP. To use Chinese, I installed the Tianhui Compatible Chinese Character System TechWay SCS V3.2 improved version. The Chinese characters are displayed normally, but when loading PY.COM and WBX.COM, it shows:

cpu error: incorrect opcode.
killing process.

Then it freezes.
However, I can normally load and use these two input methods with the Winme DOS disk.
I don't know why. I hope experts can help!!!

Re callmessw:

This is because a small anti-freeze program under DOS is at work. You can modify the Autoexec.bat file under DOS, delete the lines containing escape or killer, or add :: at the beginning of the line to comment them out. Then restart and try. If other problems occur, such as freezing, it may be a compatibility issue with the memory manager. Then modify the config.sys file, delete or add rem at the beginning of the line to comment out the line where emm386 is located, and then restart and try.

If it still cannot be enabled, I am sorry that I can do nothing!

As soon as you see:
cpu error: incorrect opcode.
killing process.
it must be the work of KILLER.EXE. And the system crash is usually caused by non-standard code in application design or "improvement". KILLER.EXE can generally enhance the system robustness, and this function has been integrated in the format accelerator I designed.

EMM386.EXE does have compatibility problems with Chinese character systems. Try to use alternatives if possible!

What the moderator willsort said is correct!

If it still doesn't work, it is recommended that you change to another Chinese character system.

Thanks, I'll try it right away!

Users on floors 2 and 3 are indeed experienced. It turns out it was an issue with EMM386. After removing it from config.sys, the problem was solved. But it also brought the problem of excessive conventional memory usage. I don't know what the "replacement" mentioned by the brother on floor 3 is. Could you please explain?

Another thing: I also tried CCDOS97, and there was no such problem.

Once again, express great gratitude!!!

Re call-me-ssw:
The "substitutes" I mentioned refer to QEMM386.SYS, UMBPCI.SYS, etc. I often use UMBPCI.SYS.

Moderator willsort is experienced and knowledgeable, and I also highly admire him.

"Brother Ben Shi is too polite. I checked around on the site and finally decided to use UMBPCI.SYS. Just downloaded the latest version 3.65, and it果然 solved the problems with py.com and wb.com.

Another thing: I used Chengran CCDOS 97 Mingtai Oriental Express Special Edition, which only has Chengran Pinyin. I want to add a Wubi, but I don't know the format and requirements of the code table (TXT file). The files decompiled from the Wubi input method of Win98 don't work. Please continue to ask experts for advice!"
