2.1 CENTRAL PROCESSING UNIT (CPU)
Step 1: Pull the lever sideways away from the socket and then raise the
lever up to a 90-degree angl e.
Step 2: Look for the bl ack cut edge on socket, and the white dot on CPU
should point forwards this bl ack cut edge. T he CPU wi ll fit onl y in
the correct orientati on.

NF325-A7
Step 3: Hold the CPU down firml y, and then close the lever to complete
the i nstalla ti on.
Step 4: Put the CPU Fan on the CPU and buckle it. Connect the CPU FAN
power cable to the JCFAN1. This completes the i nstallation.

Floppy D isk Connector: FDD1
The m otherboard provides a standard floppy di sk connector that
s uppor t s 360 K, 720K, 1.2 M, 1.44M and 2.88M flo ppy d isk types. This
connector supports the provided floppy drive ri bbon cables.
Hard Disk Connectors: IDE1~2
The m otherboard has a 32-bit Enhanced PCI IDE Control ler that
provides PIO Mode 0~5, Bus Master, and Ultra DM A 33/66/100/133
functionalit y. It ha s two HDD connec tors IDE 1 (prima ry ) an d IDE2
(secondary). The IDE connectors can connect a master and a slave
dri ve, so you can connect up to four hard disk drives. The first hard drive
should always be connected to IDE1.
AGP1: Accelerated Graphics Port Slot
You r mon ito r will atta c h directly to that vide o card. Thi s m otherbo ard
supports video cards for PCI sl ots, but it i s al so equi pped with an
Accelerated Graphi cs Port (AGP). An AGP card will take advantage of
AGP technol ogy for improved vi deo effi ci ency and performance,
especially with 3D graphi cs.
Peripheral Component Interconnect Slots: PCI1~5
This motherboard is equi pped with 1 standard PCI sl ot. PCI stands for
Peripheral Component Interconnect, and it is a bus standard for
expansi on cards. This PCI slot i s designated as 32 bits.
CNR1: Communication Network Riser Slot
(For Version 1.1 only)
The CNR specificati on is an open I nd ustry Standar d Ar c hi tecture, an d it
defines a hardware scalabl e riser card i nterface, whi ch supports modem
only.
Note: This CNR slot supports Smartlink CNR Card only.
Serial ATA Connect or: JSATA4~5
