I don't think you can write to a pxe server - PXE can read files from server but not write AFAIK.
Otherwise that would be dangerous and anyone would have access to server files (no authentication)?
You could write to a local disk using grub4dos...

Hi There,
In theory a pxe server is a dhcp server + tftpd server.
TFTPD supports get's and put's.
The limitation I believe is more on the "client" part aka G4D or the tftp client in use.
Does the virtual (PD) G4D virtual device (not sure if this is the right wording there) supports writing?

Hi,
Sorry, that I was not writing, but I've been away for a few days.
So, recently I was checking what can I do with the files on server from local grub4dos console.
I've checked that it it possible to write content of a file to console by using cat command - I've chosen a small file which is in the same directory as grldr file, to try that out:
cat (pd)/boot/somefile
And it worked out - I was able to see the file content.
Then I've tried to write an integer (zero) to that file using the write command:
write (pd)/boot/somefile 0
but there was an error:
Error 29: Disk write error
So it looks like writing to a server is forbidden. What do you think?
Maybe it could be made possible after some changes in ftpd server configuration.
Or maybe you have some other advice for me.

I dont this this is the tftp server the issue but i could be wrong.
Unless you have explicitly forbidden write access on your tftpd server, this one will support read and write by default.
A tftpd server is pretty secureless.
Simple test : from your windows machine, try the following :
tftp 127.0.0.1 put c:\boot.ini
I would rather think that G4D does not support write onto the virtual (PD) device.
To be checked with G4D guys.
