You do NOT mod your ps2. Everything can be done via soft mods these days. Google freemcboot and look at all the ways you can install it. The easiest way to install it without a hard mod is to use a PS1 game to run the independence exploit. You can run freemcboot via the exploit and install it at that point. Once it is installed your ps2 will boot in to an altered browser menu unless the memory card is removed or formatted.
