The Intel SRCZCR is a RADIOS controller designed to function with the on-board RAID on Intel's SE7501WV2 (and possibly other) motherboards. It adds additional RAID functionality to the on-board RAID through their ROMB (Raid On MotherBoard) functionality.
This controller is supported in FreeBSD by the "iir" driver. This driver exists at least since FreeBSD 4.6. For versions without the iir driver, you'll need the full package Intel distributes at the URL below. The rest of this how-to assumes you're on a recent enough version to already have the iir driver.
Intel distributes a FreeBSD driver at http://www.intel.com/support/motherboards/server/srczcr/software.htm. You'll get FreeBSD_212.zip (as of writing) which will contain iir-1.1.tgz. This is a FreeBSD package, but you don't want to pkg_add it, or you'll end up with an iir.ko for FreeBSD 4.1, and you'll overwrite the system iir drivers in your source tree. So just untar it instead.
You'll wind up with a bunch of source files, as well as some binaries. The usr/sbin/storcon binary is the Intel Storage Console. Copy this somewhere (I recommend /usr/local/sbin/storcon). Then run "cd /dev; mknod iir c 164 0" as root. This will make an appropriate entry in /dev for storcon to talk to.
Update 8/29/04: Intel has now released version 2.14 of the FreeBSD driver. This version is split up into multiple packages, so if you're running a version of FreeBSD 4.x or 5.x that already has the iir driver, you don't need to manually unwrap the package. The new driver is available at the same page as above, and should download as "ir1_freebsd_2.14.zip" (gotta love that consistent file naming...). This file, when unzipped, will give you another bunch of files. If you already have the iir driver (FreeBSD 4.x over 4.6 and any 5.x version), cd into the appropriate directory ("fbsd4/utils" for 4.x, or "fbsd5/utils" for 5.x) and pkg_add each of the srcd-*.tar.gz and storcon-*.tar.gz packages. These packages will install srcd and storcon for you, without messing up your existing iir driver. These packages will take care of the device creation, etc, and you'll be all set to continue on with the instructions from here.
That's it! Run /usr/local/sbin/storcon as root, and you'll get the Storage Console, just like you could get from the RAID BIOS. This package also contains a daemon, srcd, which is used to allow remote access to the RAID controller, send SNMP traps, and the like. Read through some of the docs and sources you extracted for more information about how to set it up - just copy the files where they need to go and configure appropriately.
