I copy-pasted it from your hal file.

Appoligies for that. I looked for that line, did a search. Missed it somehow.
Took that line out. Now:
/GrizzlyNu.hal:55: parameter or pin 'hm2_7i80.0.stepgen.01.dirsetup' not found

Yes, that's because the firmware currently installed
in the 7I80DB-16 has no stepgen hardware
(it looks like a configuration  for 4x7I77s)

What daughterboard are you using with the 7I80DB?

This determines the appropriate firmware so the
7I80DB pinout matches your daughterboard.

PnCConf lists 7I80DB - internal data 
7I76x2  is the only selection
I am trying to duplicate my parallel port pin to avoid rewiring.
I have not loaded a bit file into the board. I assumed the PnCConf software did that.
Under the assumption the 7I80DB could be configured the same as the parallel port,
I am not using a daughter board, using a C10 breakout board:   FEATURES:
  • IEEE 1284 Standard compatible.
  • PULL-UP or PULL-DOWN selection for inputs.
  • Buffered inputs and outputs.
  • Bidirectional pins 2-9.
  • Output pins 1, 2, 3, 4, 5, 6, 7, 8, 9, 14, 16, 17. Or 1, 14, 16, 17.
  • Input pins 10, 11, 12, 13, 15. Or 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 15.
  • Input and output pins with the close-by ground or +5vdc connections
  • Input pins 10, 11, 12, 13, 15.
  • Input and output pins with the close-by ground or +5vdc connections
  • External Enable Pin (EN).
  • Works directly with popular CNC hardware and software.
  • All TTL 5VDC signals.
  • Screw-On connections for all terminals.
  • Status LEDs for enable.

7i80db_16_mx4660x2D.bit
7i80db_16_Benezanx2.bit

Are two existing firmware imaged for the 7I80DB-16
which have parallel port compatible pinouts and include stepgens

 These would need to be written to the 7I80DB-16 with mesaflash


pncconf should be able to make a decent config for this but I would
probably select 7I92  + G540x2 and then edit the ini file to change the
card name from 7I92 to 7I80

I loaded 7i80db_16_mx4660x2D.bit 
Had to disable the pwm lines. Error file said it could not find the pwm.
After that LinuxCNC will open. Haven't tried to connect to the breakout board.
Not sure how to connect the dots between the physical pins and the hal file.
