How to program FPGA hardware

Don't know this board, but looking at the specs it has a M25P16 serial flash which is probably configuration memory. Normally you would use dip switches on the board to setup where the FPGA sources it's config: USB, JTAG, flash etc. So in this case you would configure your board to pull the configuration from the M25P16 on startup. Then you need to convert your SOF file into a JIC file (JTAG indirect configuration). Next you would setup the Quartus Programmer to configure from .jic and ensure your flash device shows up in the JTAG chain. You can start by reading the documentation that came with your board or this one: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an370.pdf
