You want STEPPING_TYPE=3.  See src/emcmot/emcmot.c

http://cvs.sf.net/viewcvs.py/emc/emc/src/emcmot/emcmot.c?rev=1.97

If you do not have home switches, you will also want to define
NO_SWITCHES in that file and recompile to make the HOME button
work properly.

I think virtually nobody is using the fourphase drive (at least
nobody seemed to be when I was trying to use it) so please report
back with your results!
