Can't access JTAG chain: Stratix III dev board

I have attached a snapshot of the board with switches positions that follows the board setup user guide when it is powered up. According to the development board setup p4-3 (SIII Development Kit User Guide), with these switch positions, the green LEDs 0-7 should flash side-to-side pattern, but in my case, it does not. This happens since downloading the sample "my_first_fpga.sof" which was the one and only successful download I did.

But even with "my_first_fpga.sof" design, the LEDs should flash but it does not, which is strange. It could have been I have downloaded the wrong "sof", and so was thinking of configuring the board to factory default by pressing the FACTORY_CONFIG and RESET_CONFIG buttons before turning on the power switch, but that still does not allow me to download anything.

So far, I've been using the embedded USB Blaster with the USB cable download method. Without an external USB Blaster cable at the moment (since I can't find any yet), is there a way to download without using JTAG mode? Passive serial (PS) seems to work, but it needs the external Blaster cable. Correct me if I am wrong.

Any suggestions on the snapshot that does not look right?

Thank you.
