+You need to build a new kernel to use this device, even if you want to
+use a loadable module.  
+
+Apply the patch to a 2.2.x kernel:
+
+# cd linux
+# patch -p1 <smart2.patch
+
+Then build a new kernel and turn on Compaq SMART2 Disk Array support.
+Create device nodes for the diskarray device:
+
+# mkdev.ida [ctlrs]
+
+Where ctlrs is the number of controllers you have (defaults to 1 if not
+specified).
 
 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
+insmod/lilo parameters.  If the driver is compiled into the kernel, must
+give it the controller's IO port address at boot time (it is no longer
 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

 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.
 
+Booting:

+You'll need to use a modified lilo if you want to boot from a disk array.
