I have some issues with installing Windows XP on the Onboard-Raid-Controller (Intel).
It is getting Blue Screen while installing. I've tried Win 7, it worked without problems. I saw the same problem with XP, I got a Blue Screen, too, even when I use the driver from your website. I used X9SCL-F M/B.
Depending on which USB FDD used. Since Windows XP didn't support NEC USB FDD, if you use NEC USB Floppy please change to another link TEAC or others.
