Hey ..
Coming up with a complete driver list for any of the Microsoft OSes is a very difficult task. For example, I found this list:
http://www.edbott.com/webl
but notice the date on it. You know there have been updates since then. There are new drivers included in Windows Updates and all Service Packs. It is really a moving target.
On the issue of compatibily, I've noticed most vendors include Server 2008 and Vista together. But watch out when it comes to the different bit (x86, x64) OSes.
Another thng is sometimes you need to be careful with Windows drivers. Who knows what version and chipset they are designed for. Each vendor can have their own customiized version. I've loaded Windows drivers and had things break and had to go back to the vendor for the right driver.
The bottom line is you need to look to the individual vendors for the driverrs. And also the PC manufacturer. Dell is usally the best source for Dell machine drivers.
There are probably going to be differences between each version of the OS.
Get the drivers from the manufacturer.

Hi
.
From my experience, and I forget the technical explanation for this, when you change to ACHI you need to reinstall the OS. It is something that needs to be selected when the OS is installed the first time. In the future, always select ACHI when installing the OS.
I've run into this exact problem with a Dell XPS 420 system I wanted to use esata on.
Hope this helps.
