 This is the easiest way to achieve a live boot of your RB493G, but it requires that you already have an OpenWrt router with net-access available. You will need to obtain an elf-image for the RB493G, and make it available to the other router. If you have enough memory available on the other router, you can put the image on the /tmp folder there, e.g., like this: This is the easiest way to achieve a live boot of your RB493G, but it requires that you already have an OpenWrt router with net-access available.
