+This driver is for Compaq's SMART2 Intelligent Disk Array Controllers.
+
+Supported Cards:
+----------------
+
+This driver is known to work with the following cards:
+
+        * SMART (EISA)
+        * SMART-2/E (EISA)
+        * SMART-2/P
+        * SMART-2DH
+        * SMART-2SL
+        * SMART-221
+        * SMART-3100ES
+        * SMART-3200
+        * Integrated Smart Array Controller
+        * SA 4200
+        * SA 4250ES
+        * SA 431
+        * RAID LC2 Controller
+
+It should also work with some really old Disk array adapters, but I am
+unable to test against these cards:
+
+        * IDA
+        * IDA-2
+        * IAES
+
+
+EISA Controllers:
+-----------------
+
+If you want to use an EISA controller you'll have to supply some
+modprobe/lilo parameters.  If the driver is compiled into the kernel, must
+give it the controller's IO port address at boot time (it is not
+necessary to specify the IRQ).  For example, if you had two SMART-2/E
+controllers, in EISA slots 1 and 2 you'd give it a boot argument like
+this:
+
+        smart2=0x1000,0x2000
+
+If you were loading the driver as a module, you'd give load it like this:
+
+        modprobe cpqarray eisa=0x1000,0x2000
+
+You can use EISA and PCI adapters at the same time.
+
+
+Device Naming:
+--------------
+
+You need some entries in /dev for the ida device.  MAKEDEV in the /dev
+directory can make device nodes for you automatically.  The device setup is
+as follows:
+
+Major numbers:
+        72      ida0
+        73      ida1
+        74      ida2
+        75      ida3
+        76      ida4
+        77      ida5
+        78      ida6
+        79      ida7

+/dev/ida/c0d0p3         Controller 0, disk 0, partition 3
+
+/dev/ida/c1d1           Controller 1, disk 1, whole device
+/dev/ida/c1d1p1         Controller 1, disk 1, partition 1
+/dev/ida/c1d1p2         Controller 1, disk 1, partition 2
+/dev/ida/c1d1p3         Controller 1, disk 1, partition 3
