+# Notes on the Comtrol Rocketport driver:
+#
+# The exact values used for rp0 depend on how many boards you have
+# in the system.  The manufacturer's sample configs are listed as:
+#
+#               device	rp	# core driver support
+#
+#   Comtrol Rocketport ISA single card
+#		hints.rp.0.at="isa"
+#		hints.rp.0.port="0x280"
+#
+#   If instead you have two ISA cards, one installed at 0x100 and the
+#   second installed at 0x180, then you should add the following to
+#   your kernel probe hints:
+#		hints.rp.0.at="isa"
+#		hints.rp.0.port="0x100"
+#		hints.rp.1.at="isa"
+#		hints.rp.1.port="0x180"
+#
+#   For 4 ISA cards, it might be something like this:
+#		hints.rp.0.at="isa"
+#		hints.rp.0.port="0x180"
+#		hints.rp.1.at="isa"
+#		hints.rp.1.port="0x100"
+#		hints.rp.2.at="isa"
+#		hints.rp.2.port="0x340"
+#		hints.rp.3.at="isa"
+#		hints.rp.3.port="0x240"
+#
+#   And for PCI cards, you need no hints.
+
+# Notes on the Digiboard driver:
+#
+# The following flag values have special meanings in dgb:
+#	0x01 - alternate layout of pins
+#	0x02 - use the windowed PC/Xe in 64K mode
+
 # Notes on the Specialix SI/XIO driver:
 #  The host card is memory, not IO mapped.
 #  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
