The mesaflash command should work (but without the parenthesis around the file name)

Looks like flash went through no problem. 
on the pcnconf I chose 7i92-internal Data with ?firmware?

And on the I/O connector pages I match the pin outs to the BOB ?

Just noticed avidcnc has all the xml files for there machines could I import this into pncconf or not what I am looking for , just hopping for the easiest way

You should run pncconf with a similar firmware type
(g540 is probable as close as you can get)
This should setup the step/dir and spindle PWM

The I/O mapping will likely require hand editing of the hal file.

I don't think the Avid CNC XML files will be of much help.

Maybe confused myself used the adopt board in pncconf thinking this is the correct way of doing this because bitfile was sent to me to write to the board. The I/O connector pins don't add up to how many I need to work with the BOB that came with the cnc . I guess there's a way to add more pins in the Hal file but don't understand how to do that.

Note that with the pncconf G540 configuration you need to disable any
stepgens,pwmgens, encoders, etc that you are not using to make the associated
pins available as GPIO. For your configuration, that means you set the number of
stepgens to 5 maximum, the number of pwmgens to 1 and the number of encoders to 0

One way to learn how to change the hal file is to assign one
available pncconf available GPIO pin to a LinuxCNC input function
and another available GPIO pin to a LinuxCNC output function, create a
working hal file (with scaling etc setup properly) and then
use the GPIO commands in the hal file as examples to copy-paste
to create additional GPIO connections. You also need to look
at the GPIO number to Header or DB25 pin number translation
to match your machine connections.

Have you tried creating a hal file with some GPIO bits assigned for limit switches etc?

At the moment was trying to figure out how to mach I/O pins to the BOB numbering starts off with 0 , 0 , 003  on second I/ O  and first I/O starts off with 17 . The numbering doesn't match at all.
