Windows XP mouse settings...

I recently upgraded from Windows 98SE to Windows XP. But the mouse
sensitivity/pointer speed is too slow for me. I have the pointer speed
set to its fastest and pointer precision turned off. Windows 98SE had
the best mouse sensitivity/speed and the screen wrap feature. Is there
anything I can tweak in the XP registery settings so as to emulate the
mouse sensitivity/speed and the screen wrap feature in Windows 98SE?
If so, how do I do it and what would be the correct settings?

Thanks.
