Ok, I've received a lot of answers to my message
regards the error like: newfs .... that NetBSD
1.0 install pack generate during installation.
It seems to be an error message to be ignered
so, next time, I will continue the installation
anyway.
But, I've got another question for you:
- at the end of the installation, using the 
  df Unix command it recognize that:

	root_device	/       (it seems to be the floppy)
	sd1a		/mnt
	sd1e		/mnt/usr

  is that normal ?

Regards and thank you at all.
