   1 This driver is for Compaq's SMART2 Intelligent Disk Array Controllers.

   3 Supported Cards:
   4 ----------------
   5
   6 This driver is known to work with the following cards:
   7
   8         * SMART (EISA)
   9         * SMART-2/E (EISA)
  10         * SMART-2/P
  11         * SMART-2DH
  12         * SMART-2SL
  13         * SMART-221
  14         * SMART-3100ES
  15         * SMART-3200
  16         * Integrated Smart Array Controller
  17         * SA 4200
  18         * SA 4250ES
  19         * SA 431
  20         * RAID LC2 Controller
  21
  22 It should also work with some really old Disk array adapters, but I am
  23 unable to test against these cards:
  24
  25         * IDA
  26         * IDA-2
  27         * IAES

  30 EISA Controllers:
  31 -----------------
  32
  33 If you want to use an EISA controller you'll have to supply some
  34 modprobe/lilo parameters.  If the driver is compiled into the kernel, must
  35 give it the controller's IO port address at boot time (it is not
  36 necessary to specify the IRQ).  For example, if you had two SMART-2/E
  37 controllers, in EISA slots 1 and 2 you'd give it a boot argument like
  38 this:
  39
  40         smart2=0x1000,0x2000
  41
  42 If you were loading the driver as a module, you'd give load it like this:
  43
  44         modprobe cpqarray eisa=0x1000,0x2000
  45
  46 You can use EISA and PCI adapters at the same time.

  49 Device Naming:
  50 --------------
  51
  52 You need some entries in /dev for the ida device.  MAKEDEV in the /dev
  53 directory can make device nodes for you automatically.  The device setup is
  54 as follows:

  56 Major numbers:
  57         72      ida0
  58         73      ida1
  59         74      ida2
  60         75      ida3

  74 The device naming scheme is:
  75 /dev/ida/c0d0           Controller 0, disk 0, whole device
  76 /dev/ida/c0d0p1         Controller 0, disk 0, partition 1
  77 /dev/ida/c0d0p2         Controller 0, disk 0, partition 2
  78 /dev/ida/c0d0p3         Controller 0, disk 0, partition 3
  79
  80 /dev/ida/c1d1           Controller 1, disk 1, whole device
  81 /dev/ida/c1d1p1         Controller 1, disk 1, partition 1
  82 /dev/ida/c1d1p2         Controller 1, disk 1, partition 2
  83 /dev/ida/c1d1p3         Controller 1, disk 1, partition 3
