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.
