The only way (so far) to put XP Pro on a dimension 9200 is to change
the Sata/raid controller settings in the bios from RAID ON to automatic detect sata/raid. After that you can install xp pro with SP2, SP1 will
not work, it will load just fine but you will not have SATA/RAID installed
in xp. If you don't mind this then it will be ok. If you decide to try &
install the sata/raid drivers after you install xp it won't let you because
you have it disabled in the bios. If you re-inable from bios you will get the
Blue screen of death.
