Tick Option negotiation,show progress bar,Translate unix file names ,Bind TFTP to this address “10.0.0.2”,Allow “” as virtual root. >Browse the image file as the “Base Directory” >Tick only “TFTP Server” and leave all unselected Server Interfaces = use “10.0.0.2” interface (Your LAN Wired Interface IP connected to Router LAN Port) Step 1 :Configuring a TFTP server on your Laptop.ĭownload the “tftpd32” software from the internet and install on your laptop. Method 1 : Use of My laptop as the TFTP Server ROMMON or also known as bootstrap program.
