Here's what happens when computer is turned on: Intel screen appears for a second or so. The screen with details about RAID set up (Intel Matrix or whatever - the press Cntrl - I screen! ) for a couple of seconds. Then a black screen with the letters BA in the lower right hand corner comes up for several seconds. What is this screen? Can I get the computer to skip it? Then the XP logo screen. Computer seems to be working OK. I don't understand that black screen though.
