And the second problem is solved! But, it creates another issue. I use a serial LCD and when I used the HSPLL, I couldn't get the LCD to work correctly. Perhaps someone reading this thread has encountered this before.

I'm using a 20mhz crystal. I use $4054 for the LCD speed. I defined my OSC as 20. If I use the HSPLL setting, what speed do I have to set the LCD at?
