First, u must use external or internal voltage reference on the microcontroller so that u can use the ADC.
Using external voltage reference must attached on pin AREF.
I don't know about ATMega128 internal ADC yet, but if it is atmega32, u can change the register ADCSRA, ADMUX, and SFIOR to control the ADC.
