  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
