enabling write back cache in vista ?

[newls1]

I just got all my new hardware this morning, and to make a long story short, I setup my raid 0 inside the ICH9R bios, 64k stripe, etc.... installed VISTA which took all of about 10 minutes to do, I then installed the INTEL INF file package, then installed the Matrix storage manager utility, rebooted, went into "system" and for some reason I cant "enable Write back cache" why? I did install the needed .sys file while loading Vista, what did I do wrong? The HDD's that im using for this Raid-0 array are Seagate 320GB'ers SataII (both of which have the jumper removed for SATAII operation. Any advice would be great. I'm including a snap pic of my freshly installed Vista64 SP1 OS.

The intel drivers take over control of these options.

Launch the Intel raid manager and under that right click the raid array and enable write back cache there.
