OK, let's reboot to get rid of all the installed modules, etc. and do this
by hand rather that by script. As user root from a terminal window in X do:

cd /usr/local/nist/emc

insmod -v /usr/src/rtl/modules/rtl_sched

insmod -v /usr/local/nist/emc/plat/rtlinux_09J/lib/steppermod.o
SHMEM_BASE_ADDRESS=0x3F00000 PARPORT_IO_ADDRESS=0x378

plat/linux_2_0_36/bin/mmio -ini 64stepper.ini &

plat/linux_2_0_36/bin/mmtask -ini 64stepper.ini &

plat/linux_2_0_36/bin/xemc -ini 64stepper.ini

The long commands may wrap to the next line in the terminal window, that's
OK, just hit ENTER at the end. This should get the EMC started without all
the fancy error checking stuff in that script file. Let me know if you get
any errors from this procedure. You are not the only guy to have trouble
with these script files, although I can't figure out what the problems are
caused by.

Thanks,

Matt

P.S. If you want to call today (Memorial Day), I'm around and not that
busy, so if you need to do that it's OK.
