Once you load the MCS file multiboot settings, the configuration engine will jump to the required address if IPROG is enabled in the design and load the multiboot image.
If this fails and fallback is enabled then it will fallback to the image kept at address 0. Refer to XAPP1247 or UG470. https://www.xilinx.com/support/documentation/application_notes/xapp1247-multiboot-spi.pdf
