Help with 5 axis EMC?

Help from the group please,

I'm trying to setup EMC from the BDI disk to control a 5 axis mill
(GEM 500, with 2 stacked rotary axis). The EMC is running on a AMD
K6-2/450 with 128MB, and 16MB video (not integrated). I have looked
at the 4 axis files available from the Dropbox, and patterned my
changes after them, plus applying a little knowledge - yet all I can
get to show on screen is X, Y, Z axis. The EMC will not give an
error if I enter under Manual Mode G01 X1 Y1 Z1 A2 B3, so it is the 6
axis kernel. I have modified the the following files;
usr/local/emc/mini5.ini - added A, B axis sections, 5 axis total,
calls tkemc5. Copied from mini.ini.
usr/local/emc/mini5.run - calls mini5.ini file, added "|tkemc5"
to "display in foreground" section
usr/local/emc/plat/linux_2_2_18/bin/tkemc5 - copied from tkemc,
modified all that I can see that applies, following the pattern.
usr/emc_kde/emcmini5 - copied from emcmini,
calls /usr/local/emc./mini5.run
Added desktop icon executing /usr/emc_kde/emcmini5

What else is needed to get this working? Help!!! I've been trying
this since NAMES '01, and frustration abounds! I have no Linux
experience, but have found it is similar to Windows, which I use
every day. Please help - any thoughts/suggestions are appreciated!
