You can set up TFTP server very quickly using TFTP32 sofware. It is free.

If you wish, you can use linux machine to do the same task.
sudo apt-get install xinetd tftpd tftp
sudo touch /etc/xinetd.d/tftp
sudo nano /etc/xinetd.d/tftp
Paste this code:
service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = nobody server = /usr/sbin/in.tftpd server_args = /home/tftpboot disable = no }
sudo mkdir /home/tftpboot
sudo chmod -R 777 /home/tftpboot
sudo chown -R nobody /home/tftpboot
sudo service xinetd restart
