There is definitely USB code that accesses some of the other RAM pages, but I haven't traced to see if/when it's called. I would guess it's for receiving bulk data or something along those lines. And it's also completely possible that it's never actually used by the OS, but it's something to look in to. --[[User:Dan Englender|Dan Englender]] 21:52, 24 March 2006 (PST) | There is definitely USB code that accesses some of the other RAM pages, but I haven't traced to see if/when it's called.

Really I figure this is where we should decide what pages should be temporary and what could be long term. Also, if any current programs use ram pages we should claim them and possible leave some kinda of marker on the page it self. Last is to find out when tios uses these pages. --Jim e 20:14, 24 March 2006 (PST)
