DXDIAG Settings

Good morning everyone. Is there a way when I adjust my acceleration settings for audio from full to basic, to have the system keep this setting saved, so on the next reboot, I don't have to keep going back into DXDIAG to change it. I ask this because it increases my memory usage alot when I access DXDIAG. EX: after boot up = 74,828 used / After accessing DXDIAG = 85,652 used. I hope I am not confusing matters. I like my system load as low as possible before running FS9. I use Win2000pro (tweeked to 14 processes running)Thanks in advance for your help.
