+========================================
+The COPS LocalTalk Linux driver (cops.c)
+========================================
+
+By Jay Schulist <jschlst@samba.org>
+
+This driver has two modes and they are: Dayna mode and Tangent mode.
+Each mode corresponds with the type of card. It has been found
+that there are 2 main types of cards and all other cards are
+the same and just have different names or only have minor differences
+such as more IO ports. As this driver is tested it will
+become more clear exactly what cards are supported.
+
+Right now these cards are known to work with the COPS driver. The
+LT-200 cards work in a somewhat more limited capacity than the
+DL200 cards, which work very well and are in use by many people.
+
+TANGENT driver mode:
+	- Tangent ATB-II, Novell NL-1000, Daystar Digital LT-200
+
+DAYNA driver mode:
+	- Dayna DL2000/DaynaTalk PC (Half Length), COPS LT-95,
+	- Farallon PhoneNET PC III, Farallon PhoneNET PC II
+
+Other cards possibly supported mode unknown though:
+	- Dayna DL2000 (Full length)
+
+The COPS driver defaults to using Dayna mode. To change the driver's
+mode if you built a driver with dual support use board_type=1 or
+board_type=2 for Dayna or Tangent with insmod.
+
+Operation/loading of the driver
+===============================
+
+Use modprobe like this:	/sbin/modprobe cops.o (IO #) (IRQ #)
+If you do not specify any options the driver will try and use the IO = 0x240,
+IRQ = 5. As of right now I would only use IRQ 5 for the card, if autoprobing.
+
+To load multiple COPS driver Localtalk cards you can do one of the following::
+
+	insmod cops io=0x240 irq=5
+	insmod -o cops2 cops io=0x260 irq=3
+
+Or in lilo.conf put something like this::
+
+	append="ether=5,0x240,lt0 ether=3,0x260,lt1"
+
+Then bring up the interface with ifconfig. It will look something like this::
+
+  lt0       Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-F7-00-00-00-00-00-00-00-00
+	    inet addr:192.168.1.2  Bcast:192.168.1.255  Mask:255.255.255.0
+	    UP BROADCAST RUNNING NOARP MULTICAST  MTU:600  Metric:1
+	    RX packets:0 errors:0 dropped:0 overruns:0 frame:0
+	    TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 coll:0
+
+Netatalk Configuration
+======================
+
+You will need to configure atalkd with something like the following to make
+it work with the cops.c driver.
+
+* For single LTalk card use::
+
+    dummy -seed -phase 2 -net 2000 -addr 2000.10 -zone "1033"
+    lt0 -seed -phase 1 -net 1000 -addr 1000.50 -zone "1033"
+
+* For multiple cards, Ethernet and LocalTalk::
+
+    eth0 -seed -phase 2 -net 3000 -addr 3000.20 -zone "1033"
+    lt0 -seed -phase 1 -net 1000 -addr 1000.50 -zone "1033"
+
+* For multiple LocalTalk cards, and an Ethernet card.
+
+* Order seems to matter here, Ethernet last::
+
+    lt0 -seed -phase 1 -net 1000 -addr 1000.10 -zone "LocalTalk1"
+    lt1 -seed -phase 1 -net 2000 -addr 2000.20 -zone "LocalTalk2"
+    eth0 -seed -phase 2 -net 3000 -addr 3000.30 -zone "EtherTalk"
