I tried the 190 OC flashed to the SPI and it seems to be working on 2 of my FPGAs. 2 COM ports are detected (22,23 for me). The weird thing is see the LEDS light up on 4 of the FPGAs as work is found, but MPBM is only reporting work from 2 of the FPGAs. 
The only thing that I had to do differently is leave SW6 #1 ON in order for it to hash.
Guess it's the same issue I have regardless of which bitstream I'm using. I'm only getting work from 2/4 of the FPGAs. Any help would be greatly appreciated. Thanks!

When the leds flash, do they flash on the pair of FPGAs at the same time? If so, you have the DIP switches set wrong on P1 and P2. sw2 on p1 and p2 need to be OFF to run the array in paired Icarus mode.
They are flashing independently.
Per EB:
I used the following:
SW2 all on
SW5 all on
SW3 #2 off
SW4 #2 off
