you can use HENC i believe to enable homebrew on a 2.71... but its a pain in the ass... i reccomend downgrading that 2.71 to a 1.5 then upgrading to 3.03 oe-c and being able to do homebrew AND the newest features.... check and see if you have a ta 802 motherboard though... you can find all of these out on these wonderful things called stickys on the site!
