Programming terasic tr4 without usb cable

I need to program the device in a way that I will be able to take the kit somwhere and when i'll turn on the power my software will automatically be programmed to the fpga.

I don't understand if i'm supposed to use the max II or the flash memory.

I have a .sof file that i want to program to the device so i'll don't need to program it every time,just turn on the power and the fpga will start working,for example if there is a way to load my .sof file to the MAX II and when i turn on the power the MAX II will program the .sof file to the fpga.How can I manage to do so?

Thanks.
