Where does one find the bit.bin files for the FPGA?

Obviously a newb to Parallella.
I have both the kickstarter 7020 and the newer 7010 version cards.
I have looked at and followed the microSD build process and have been looking for the bit.bin file for the BOOT partition.
I am assuming (danger) the 7010 and the 7020 files are different and one should not be run on the wrong chip. Is this a valid assumption?
My other questions are -
which images are correct for the desktop boards with video?
Where is the bit.bin file?
Thanks!
