Well, I suggest you take you USB connector plug, and hook it up to you SB54200. Now, all that will do is allow easier communication between you hoveram CPU and you F200. I am assuming you're using an F200, right?
Now, the RAM data port 2 should be open. Plug your modem into that via speghetti. That should help a bit, too.
Now, if you're wondering where the applesauce goes, my answer would have to be nowhere. it's a common misconception that you should quickly pour the applesauce onto the motherboard to make it taste better, but I think some salsa might do the trick. I'm not positive though.
I should also mention that the Rimdazzle 412 video card is now out by GeVidia, and should enhance your "dodgy" 233 into about a 412. This wont enhance the processing speed at all, but it should set you back $350-400. That's about.....carry the elevendy.....$1000-2000 dollars Australian.
Other than that, I can't help you one bit. Sorry. :\
