Virtex-6 Multiboot configuration without physicaly connected Revision Select pins

Hello!

We have board which has not connect RS pins to the BPI-flash (JS28F256P30 if it's matter, address pins [22:0] are connected). 

It is possible to create multiboot without that pins?

Bitstream (Golden and Multiboot) are fit with a margin.

I tried to edit WBSTAR embedded in bitstream and then IPROG to load it with desired address, but without any result's it just not loaded properly. May be it has some trick to do that?

I read a post  when

Is the flash having 25 address pins? How did you connect the two most significant pins of flash on board? If you don't have to select revision during initialization, and the golden is placed at zero, you should be able to find the image as long as the two pins are with a value of 2'b00.
