ATmega328 Bootloader?

I have been looking at the Atmel bootloader for the USB chips. From what I have found it is only used with USB chips.

Where does the bootloader in the 328 come from? Is there a hex file for it?

look at your boards.txt in the arduino install, it will tell you what file it uses for the bootloader

Thanks,

Is there a hex file for the USB/UART bridge chip? Is there source for the USB/UART bridge chip?
