Bootloader question

thanks for the answers. I want to execute the code I write in Assembly language on the Arduino platform without buying a more expensive AVR development board. I know all the high-level languages (except Cobol) and Assembly still has it's place. Whatever floats your boat!! Assembler is used in the QuadCopter applications with the ATmega's which is my particular reason to learn it.
thanks for replying!!
