You know that we ship these  systems  with  PPCBoot  and  Linux  pre-
installed, and tested?

This is NOT ok, at least from the administrative point of view: TQ is
using 00:D0:93... ethernet addresses for their products. You can read
the correct setting from the label on the module (it might be on  the
bottom side, so you have to unplug the module from the STK).

Check the jumpers on the STK8xxL  board;  the  relevant  jumpers  are
X.12, X.13, X.14 and X.32. With X.12, X.13 and X.14 you can select if
you  are  using  SCC1  or  SCC2;  for  the  MPC860,  SCC1 is used for
ethernet, so you must set a jumper on positions 1-3 and 2-4  for  all
of  these.  X.32 connects some port pins with the USB interface; when
you want to use SCC1 for ethernet, NO jumper must be set on X.32.


I guess it's the jumpers on X.32. Remove them.
