Okay, someone answer this one. Got the board up and running. It now recognizes both my IDE and SATA devices. When I go to install XP it makes it seems to go fine but then two things happen: One, it skips the check for a previous version of windows. Second, after formating the drive, it goes ahead to the file setup, and while in the middle of it, it will instantly turn the power off to the machine. No warning, no anything- it is like the power cord is pulled. Sometimes it does it at the start of the file setup screen, and sometimes it makes it to about 30% complete! I can't tell if this is motherboard, drive, memory, or processor related.... Arrrggh!
