Atmega328 with arduino NG

I have a Arduino NG with Atmega8. To improve its performance for better projects, i want to use it with ATMEGA328. Can I do so ?
In Arduino IDE, while selecting the board, the only options available are 'ARDUINO NG OR OLDER W/ ATMEGA8' or 'ARDUINO NG OR OLDER W/ ATMEGA168'.
Please help.

Thank you :slight_smile:

Don't use the ATmega328, use the ATmega328p (with the 'p').
And select the "Arduino Uno" board for your NG with the ATmega328p.

You should be able to drop in an Uno bootloaded part with no issue.
