    1 This driver is for Compaq's SMART2 Intelligent Disk Array Controllers.
    2 
    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
   28 
   29 
   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:
   55 
   56 Major numbers:
   57         72      ida0
   58         73      ida1
   59         74      ida2
   60         75      ida3
   61         76      ida4
   62         77      ida5
   63         78      ida6
   64         79      ida7
   65 
   66 Minor numbers:
   67         b7 b6 b5 b4 b3 b2 b1 b0
   68         |----+----| |----+----|
   69              |           |
   70              |           +-------- Partition ID (0=wholedev, 1-15 partition)
   71              |
   72              +-------------------- Logical Volume number
   73 
   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
