Building bitfiles for 7i92

I have a 7i92 that would like to try to build a custom bitfile for.
I selected the 7i92 for the possibility of an easy connection over a distance between computer and my electrical enclosure.

The board I am trying to drive is this one: www.shop.cncdrive.com/index.php?productID=914

But I am not certain of what will connect where so I want to try different things (and will therefore need different bit-files) on the bench before final install.

The issue I am having is that I can't seem to find sourcecode for any 7i92 bitfiles I find.

Can a bitfile for the 7i92 be built from github.com/LinuxCNC/hostmot2-firmware/tree/master/src ?
Perhaps from mesanet.com/software/parallel/7i92.zip ?

Is the relevant code somewhere else?

Or am I simply not understanding how the sausage is made?
I feel I have a decent understanding for how a 5i25 bitfile gets built, but I can't really tell with the 7i92.

Any information and/or answers would be appreciated.

7I92 bitfile building is basically identical to 5I25 bitfile building
(and all Hostmot2 firmware building)

I would start with 7i92.zip (though any FPGA card zip file will do, the all have the
same firmware source files ) and use the seveni92.xise project file.

this board has a standard parport output
one or 2
so you can find all the bitfiles alredy in the ZIP file

There are also extras if you do not need the 10Stepgens

i did go with 6Stepgens on the 5Axis with ATC
its a 7i92 and 2 parport outs
