AGP Slot
The AGP Pro slot is backward compatible with AGP Pro and 4xAGP
graphics cards, which have fewer pins than AGP Pro cards. Because of
this, care must be taken when installing a graphics card into this slot, as
doing so incorrectly can damage your motherboard. For AGP Pro cards,
you should remove the orange sticker covering one end of the slot. For
other cards, leave this sticker in place and make sure your card does not
plug into the section it covers. A general rule of thumb is to make sure
your card fills the section of pins nearer the center of the motherboard first,
then the end toward the edge of the motherboard if there are more pins not
seated. If the I/O shield of your card is flush with the edge of the mother-
board, the card should be inserted correctly.
