I've been running XP32 on the system in my sig, but I've decided to upgrade to Vista Business 64-bit because I got a free copy through my school. I had been running my ICH9 SATA controller in IDE mode, but I decided to install Vista in AHCI mode. I downloaded the Intel Matrix Storage Manager Driver and followed the directions to extract the files and put them on a USB flash drive. During Vista installation I clicked "Load Driver" at the partitioning screen and plugged in the flash drive. The problem is in the driver list nothing shows up unless I untick the hide unnecessary drivers checkbox. I've tried selecting and installing several different things that appear to be a match for my hardware, but each time once the install completes my AHCI controller is using the default Windows drivers instead of the Intel drivers. Also, if I try to install the Intel drivers once Vista is installed I am told that my system doesn't meet the minimum requirements for the driver. I've reinstalled Vista ~8 times in the last 2 days trying to figure this out and I'm about ready to forget it and just install in IDE mode without the Intel drivers, because there appears to be something fubared in them.
