China DOS Union

I installed DOS 6.22 from the diska disk on the client machine.
I downloaded it from this site and extracted it. There were dosdisk1.exe dosdisk2.exe dosdisk3.exe
These three files are there. When I click them, it says insert floppy to write
After I click OK, it then says the current image format is not supported by zhe disk drive
My English is poor, so I don't know what it means. I'm asking everyone to help explain it to me.

I suggest going to www.freedos.org and downloading FreeDOS to install, or install MS-DOS 7.10 instead... MS-DOS 6.22 has long been outdated.

If your English is poor, use Kingsoft Powerword.
I use it often too.
Plenty of content, and cheap.
If that really doesn't work, then look it up in an English dictionary.
This really isn't a technical problem. faint~~

I downloaded ms-dos6.22 from this site.
