Atmega 328 vs 328P Problem

I tried Optiloader earlier today and now again. Cannot get it to work. I cannot tell if it is programming the board or not as nothing is on the serial monitor. But when I use the programmed board and try to load a sketch, I get an Avrdude error. These problems led me to buy the avrisp this morning and I am able to burn the bootloader with it. Do you know what the fuse bits should be set to?
