It's really difficult to find this tools because it's reserved to oem integrater.
You can find some information here: http://www.station-drivers.com/telechargement/intel/sata/OEM_Technical_Guide_10_5_rev1_01.pdf
You could try to contact you OEM for the file.
I made a nagios plugin like I already explain here http://communities.intel.com/thread/15669 but need all the version of the raidcfg32 tools.
You need the same version of drivers and version of the tools to use the ST command.
I'm looking for the last version of ICH models.
v188.8.131.520 last version
v184.108.40.2062 v220.127.116.111 v18.104.22.1682 version here: http://driverscollection.com/?aid=24606005865EvJIbfCFtSmwZchn
If I'll found the 8.2 version I will let you know.
