Hi, i am a newbie to Arduino... just got a Uno Smiley.
I wanted to make an extra 328 chip with Arduino boot-loader, just in case i mess up the one i have.
I was looking into Arduino Boot Cloner
arduino.cc/playground/BootCloner/BootCloner
Very informative, but could some please guide me to do the same with Atmega 328 chip (Boot Cloner for Atmega 328)?
Thank you.
this should answer your problem

Hi Arnonh,
After going through » Preparing ATmega’s with ISP » JeeLabs, I could understand that each time you are programming your arduino you are burning the IDE as well.
Please correct me if I am wrong.
Isn't it possible to just load the Atmega 328 chip with the IDE first and load the code through the already existing Arduino?
Please clarify. Thank you.
if by IDE you mean bootloader
then after the first time you prepare the atmega
you will be able to use it as any normal arduino
just one note however:
when you follow his guide you will get the bootloader for the old boards
so you will need to change your board in the menu every time you use the new atmega
or edit the prepare sketch
'when you follow his guide you will get the bootloader for the old boards
so you will need to change your board in the menu every time you use the new atmega or edit the prepare sketch'
I didn't understand that part 
Could you please explain it in detail?
I will try to make and post a sketch usable for the Uno
tomorrow(but no promises)
Thanks Arnonh, you are a life saver.. 
I'm eagerly waiting for the Uno sketch. Would be of great help if you can post it.
use this instead of data_blink.h in isp_prepare sketch
i believe it should work but i haven't tested it fully
