-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
