1This driver is for Compaq's SMART2 Intelligent Disk Array Controllers.
2
3Supported Cards:
4----------------
5
6This 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
22It should also work with some really old Disk array adapters, but I am
23unable to test against these cards:
24
25    * IDA
26    * IDA-2
27    * IAES

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

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

56Major 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

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
