Help: Creating a file...

[Alex]

Hi all,

I still cant create a file using rtems i386 686 bsp, linux :-(
Does rtems has any default file system ?
The code works well but I cant see the file :-(

I want to do the folowing:
I try the rtems program using a floppy disk, and grup booting.
I want to create a file in that floppy disk when I execute the rtems program, is this possible?
Do I need any extra tool?
Any tips? advices? Source code? 



Please see the source code i am using (from rtems samples):
The code work well, but where are the file?

Thanks a lot...
