Are you running on qemu?

This is very likely newer than what the Intel driver in the code base
supports. You will have to use Till's libbsd kit (libbsd-port RTEMS CVS
module). This driver is much newer and supports newer chips.

This works with the telnetd network-demo. fileio is not setup as a
networked
application so this is not particularly surprising.
