I have met some problems when I tried to install Windows XP professional. The installation died after message of "setup inspecting your system....', I have tried to resolving this by turning SATA off in BIOS, but it didn't solve the problem. I don't know why. Maybe become the cpu of my machine, T9300.
I had contacted with Dell. The answer is it doesn't support this work ^_^.
Here is my machine
Intel Duo T9300
200 GB SATA hard drive
