STFM TOS upgrade to 2.06

[Naparovitse]

Hi,
I recently bought a ram update for my 520STFM (MP210A Kit) and along with the ram kit the seller also sent a kit to update the ROM, but I don't know if I can connect it to my atari. Can anyone help me to do this?
My board version is a C070789-001 REV.D and the picture of the rom is this...

the ic plug goes into a rom socket and all the cables are soldered onto the cpu. I think it's a Hard&Soft Germany (H&S) TOS card, I don't know exactly...

A photo of the bottom of the card might help identify it, sometimes they have manufacturers marks.

Thanks for your answers.
Yes it really does look like Hard&Soft Germany (H&S) TOS card. However here is a picture of the back.

However after consulting the manual I have a doubt. The review board of my 520 STfm is the one in the following photo

And in the manual it says to connect at the Rom Socket U4, but in my revision is not U4, Where i can connect?

manual pic is a 260/520ST Mainboard and not a 1040 Board. When your have a 520STFM than it is a 1040 layout Board you have.

Like Frank says your motherboard photo matches page 9, 1040ST (Model B)
