Hello all, I have a desktop with three hard drives in it that I can boot from one to the other. One has XP on it, one has 98, and the other has 95. It has been working fine until I installed a new pci card in it. The card is a two port usb with a two usb pin-block on it. The problem is when the card is in, the computer will boot up in 98 and 95, but locks up after it POSTs in XP. I just get a blank screen. The card works fine in 98. I have booted up the computer with just the XP HD connected and get nothing. If I just connect the 98 HD, it works fine. If I leave everything connected and pull the card, everything works fine. I don't understand why the card works fine with 98 but not XP when I'm using all the same hardware.
