i guess the thread should be named PPC!
anyway , "2" is the key to press to disable the whole card, i dont recall the buttons for "memory" and "ppc" ..
sadly i dont have the manual anymore but i am pretty sure that "f" is MEMORY and i belive "s" was something also but hell if i wanna try it

i am having to much pain atm with broken cia's so i am just glad my damn machine works at all.
cheers
