 #
+# The LM87 is unique in having integrated scaling resistors, rather
+# than external resistors common to most sensor devices.
+# These apply to the first 6 voltage inputs in0-in5
+# (+2.5, Vccp1, +3.3, +5, 12, +Vccp2). As the scaling is fixed inside
+# the chip for these inputs, it is fairly certain that the
+# motherboard connections match these labels, and that the
+# driver computations are correct. Therefore they do not need to
+# be overridden here.
+#
+# Note: AIN1 (-12?), AIN2 (-5?) and CPU2_temp require changing
+# #defines in the driver and recompiling!!!
+#
 # This chip has non-standard entries in lib/chips.c so
 # the feature names are quite different from other chips.
