Funny I have a Amilo Pi2550 (Intel Chipery inside), and I was able to install Windows 7 just fine.
AFAIK One would only have to worry about the SATA Drivers when you wanted to install WinXP or Win2k.
As for Vista and or Seven the SATA Driver ~should already be on the Disk~.
So that's not your problem.
As for post-installation Drivers you can check my other Post HERE: http://forum.ts.fujitsu.com/forum/viewtopic.php?f=90&t=42486
