+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
+
+Minor numbers:
+ b7 b6 b5 b4 b3 b2 b1 b0
+ |----+----| |----+----|
+ | |
+ | +-------- Partition ID (0=wholedev, 1-15 partition)
+ |
+ +-------------------- Logical Volume number
+
+The device naming scheme is:
+/dev/ida/c0d0 Controller 0, disk 0, whole device
+/dev/ida/c0d0p1 Controller 0, disk 0, partition 1
+/dev/ida/c0d0p2 Controller 0, disk 0, partition 2
+/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
