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

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)

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
