Upload using programmer question(s)

Using Arduino Microcontrollers
6

thanks everyone..

I understand now..

a bootloader, or some sort of 'step', DOES need to be done to a blank chip before just using "Upload using programmer" to set the fuses on the chip..

Last Question:

Since 1 of my projects using the 'breadboard bootloader' (+3.3v @ 8MHz INTERNAL clock)...
and I believe they come set to run on internal clock from factory...

does (for example) writing the Breadboard bootloader to the chip first (in this case) have any special use?
(ie: is it setting any fuses differently than how the chip comes configured from the factory?)

thanks~!
