 Installing the Driver
 ---------------------
 
-If this driver was included as part of your Linux kernel source, all you
-will need to do in order to install it is:
+** Note: the latest version of the driver contains preliminary support for
+	ARCnet RIM I cards.  These are very old cards that don't use I/O
+	ports at all, but rather map the status and command ports into
+	shared memory.  To compile the driver in RIM I mode, you must (for
+	now) edit linux/drivers/net/arcnet.c, find the line that says:
+		#undef RIM_I_MODE
+	and change it to:
+		#define RIM_I_MODE
+
+All you will need to do in order to install the driver is:
 	make config
-		(be sure to choose ARCnet under "other ISA cards")
+		(be sure to choose ARCnet in the network devices)
 	make dep
 	make clean
 	make zImage

+You will know the driver is installed properly if you get some ARCnet

+
+If you use a RIM I card, you will need to give the kernel boot parameters
+specifying your card's irq, node ID, and shared memory.  For example,
+	LILO boot: linux ether=9,0x42,0xD0000,0,arc0
+if your card is node number 42h, irq 9, with shared memory at 0xD0000.
+
+NOTE that if you aren't using RIM I, the above command will still work but
+you will need to replace the node ID with an I/O port number, for example:
+	LILO boot: linux ether=9,0x300,0xD0000,0,arc0
+
+You can add the ether= parameter to /etc/lilo.conf to avoid typing this
+every time.

 You can name the device using something like "device=arc1" (for a second
 card) or "device=eth0" (for weird compatibility reasons) if you like.

+If you use RIM I, you don't need to specify io= but you must include node=
+for your ARCnet card's station ID.
