AGP Pro Slot
The AGP Pro slot is backward compatible with AGP 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 center section of pins first, then the end toward the edge of
the motherboard if there are more. If the I/O shield of your card is flush
with the edge of the motherboard, the card should be inserted correctly.
