Installing the Hardware, Part 2: Graphics and Sound Cards

		Now take a look at the different I/O (In/Out) slots on the other side of the motherboard. This board has three types of slots: AGP, PCI, and ISA.
The brown slot closest to the CPU is the AGP slot, and it is for your graphics card.  Most current graphics cards are AGP, but there are some that fit into the white PCI slots.
		When the card is installed, screw the card’s bracket to the case to prevent it from becoming dislodged.
The white slots further down from the CPU are called PCI. Your motherboard may also have one or two black ISA slots at the very end that are for older devices. Insert your sound or other cards (i.e. modem) into the appropriate slots and screw them in place.
		Near the other corner of the motherboard’s far end, you will find two rows of pins, called PN1 and PN2, that are used to attach the motherboard to the case's warning lights, speaker, and on/off switch.
The motherboard’s manual or indicators on the motherboard itself will provide information on correct attachment of these wries. In this picture, we have connected the wires of the case’s on/off switch.
		With all the wires connected, it will look something like this.
