 If you're using a loadable module, you need to use insmod to load it, and

+you can specify various characteristics of your card on the command

+and works as a module, so most of this is now unnecessary.)

+For example:
 	cd /usr/src/linux/modules
-	insmod arcnet.o io=0x300 irqnum=2 shmem=0xd0000
-You can also add a num=1, num=2 etc for additional arcnet cards that will

-** NEWS FLASH!  Starting with 2.30 ALPHA, the ARCnet driver can autoprobe
-   even as a module.  So "insmod arcnet.o" by itself should work.
+You can name the device using something like "device=arc1" (for a second
+card) or "device=eth0" (for weird compatibility reasons) if you like.
 	
 
 Using the Driver

 By the way, be sure to change all references from "eth0" to "arc0" in the
 HOWTOs.  Remember that ARCnet isn't a "true" ethernet, and the device name
 is DIFFERENT.

+Multiple Cards in One Computer
+------------------------------
+
+Linux has pretty good support for this now, but since I've been busy, the
+ARCnet driver has somewhat suffered in this respect.  For now, the easiest
+way to use multiple ARCnet cards is to build it as a loadable module and
+then do something like this:
+	insmod -o arc0 arcnet
+	insmod -o arc1 arcnet device=arc1
+(Note that in the first line, the default is device=arc0, but it doesn't
+hurt if you want to add it for consistency.)
 
 
 How do I get it to work with...?
