Today, when using Shenshan Hongye DOS Toolkit and MS-DOS 71, I found that under the Shenshan Hongye DOS Toolkit, I can use reset/restart to restart the computer and the OFF command to shut down the computer, but it doesn't work under MS-DOS. So I thought about extracting the reset, restart, and off commands and putting them into the MS-DOS 71 installation disc file, so that the next installed DOS system can use these commands.

But in this process, I encountered a big problem that I couldn't unzip the original DOS system's.PAK file. I tried many ways but couldn't, because it was encrypted!!!郁闷!!!

But the system can extract files during the installation process. Why is that?

I found the pkunzip command in the setup.bat file, but I don't know why I just can't extract it. I don't know if it's a wrong method or if a password is needed...

I hope those who have modified the DOS system installation files can help take a look...

Hehe, is the content mentioned by the楼主 DOS71_1S.PAK and other files? It seems that there is no problem with extracting or adding files here for me.

Yes, exactly this!
I don't know how you did it?
Can you send me your PAK file? Thank you!!!

Hehe, rename DOS71_1S.PAK to DOS71_1S.zip, then you can handle it with winrar. I tried, and after processing, the file can be put back into the img and the DOS installation operation can be carried out normally.

I'm relatively slow-witted. I followed what you said to convert it to ZIP format, but whether I try to extract or directly add files to it, it doesn't work...
Can you be more detailed, thank you...
Really can't figure it out...
