RST installs the driver for the RAID/AHCI controller and gives you a small app to monitor the drives. I thought I linked directly to the RST drivers you needed? If not let me know and I'll steer you in the right direction.
As far as your BIOS goes, I'd update it. Like I said before there there a ton of fixes in the previous revisions.http://www.intel.com/support/motherboar ... 022312.htm
Read that, it should tell you how to flash your board.
If you want to see which BIOS you're running download HWiNFO64.http://www.hwinfo.com/files/hw64_392.exe
Start the program and you'll see a little window pop up. In there it should tell you the BIOS version. See pic.
