The flash programmer (java binary) is also capable of examining EPCS to determine where to start the software, following the FPGA configuration -- this is how it programs software into the right spot.

The bootloader firmware source (components/altera_nios2/sdk/boot_loader_sources) is, in my opinion, commented very well for assembly language, and describes the boot-process in detail.

Note that the boot-loader is (currently) only compatible with Cyclone and Cyclone II. Stratix II support will come in a future release.
