Perhaps, I will try tommorow.

No, this is pure MS-DOS 6.22.
But I've already found reason. When I copy DJGPP to CD ( on Windows  
platform) and then from CD-ROM to DOS platform, all "-" signs are replaced  
by "_". So, insted of go32-v2 I had go32_v2 :)
When I started  go32_v2, I received "Descriptor exhausted" message. After  
corection, go32-v2 starts ok.

Thanks for your answer.
