boards.txt has the speeds used for the different boards, these speeds are set up to match the speeds of the bootloader.
If you install the Uno bootloader, then you would use the Uno board type for downloading for example, altho physically the board layout might be a promini.

Thanks a lot,it's so confusing to a starter.I used to think I can buy an arduino chip and learn avr on it without difficulty,it's wrong:(
