1.4.2 How to install a DIMM Module
1. The DIMM socket has a “ Plastic Safety
Tab” ,and the DIMM memory module has
an Asymmetrical notch”, so the DIMM
memory module can only fit into the slot
in one direction.
2. Push the tabs out. Insert the DIMM
memory modules into the socket at a
90-degree angle, then push down vertically
so that it will fit into the place.
3. The Mounting Holes and plastic tabs
should fit over the edge and hold the
DIMM memory modules in place.

1.5 Slots
The slots in this motherboard are designed to hold expansion cards and connect them to
the system bus. Expansion slots are a means of adding or enhancing the motherboard's
features and capabilities. With these efficient facilities, you can increase the
motherboard's capabilities by adding hardware that performs tasks that are not part of
the basic system.

1.5.1 ACR (Advanced Communication Riser) Slot
The ACR specification is an open Industry Standard Architecture and that defines a
hardware scalable riser card interface, which supports audio, network and modem
only.
1.5.2 AGP (Accelerated Graphics Port) Slot
Unlike the mouse ports, keyboard ports and printer ports, this motherboard does not
have built in video facilities and therefore requires a video card for one of the
expansion slots. Your monitor will attach directly to that video card. This
motherboard supports video cards for PCI and ISA slots, but it is also equipped
with an Accelerated Graphics Port (AGP). An AGP card will take advantage of
AGP technology for improved video efficiency and performance, especially with
3D graphics.
1.5.3 CNR (Communication Network Riser) Slot
The CNR specification is an open Industry Standard Architecture and it defines a
hardware scalable riser card interface, which supports audio, network and modem
only.
1.5.4 PCI (Peripheral Component Interconnect) Slots
This motherboard is equipped with 5 standard PCI slots. PCI stands for Peripheral
Component Interconnect, it is a bus standard for expansion cards, which has
supplanted the older ISA bus standard in most parts. This PCI slot is designated as
32 bit.

1.6 Connectors, Headers & Jumpers
The connectors, headers and jumpers introduced below provide you lots of
capabilities such as power supply, front panel signal revelation, IDE hard disk
connection, floppy disk connection, Wake On LAN function and USB connection.
Noticeably, a jumper has two or more pins that can be covered by a plastic jumper
cap, allowing you to select different system options.
