+This directory provides some ancillary programs necessary for
+operation of the Interlan Np100 ethernet interface.
+
+This interface is unusual in that it requires loading firmware
+into the controller before it may be used as a network interface.
+This is accomplished by opening a character special device,
+and writing data to it.
+
+The sequence of commands would be:
+
+       # npload np.image
+       # sleep 10
+       # ifconfig ix0 ...
+
+It is also possible to do post-mortem debugging of firmware failures
+by reading the local memory of the device.
+
+Typical use would be:
+
+       # npdump np.core
+
+If the device needs to be reset, you would issue:
+
+       # ifconfig ix0 down
+       # npload np.image
+       # sleep 10
+       # ifconfig ix0 up
