CHAPTER 2: HARDWARE INSTALLATION
2.1 I
NSTALLING CENTRAL PROCESSING UNIT (CPU)
Special Notice:
Remove Pin Cap before installation, and make good preservation
for future use. When the CPU is removed, cover the Pin Cap on the
empty socket to ensure pin legs won’t be damaged.
Pin Cap
Step 1: Pull the socket locking lever out from the socket and then raise
the lever up to a 90-degree angle.

Motherboard Manual
Step 2: Look for the triangular cut edge on socket, and the golden dot on
CPU should point forwards this triangular cut edge. The CPU will
fit only in the correct orientation.
Step 2-1:
Step 2-2:
Step 3: Hold the CPU down firmly, and then lower the lever to locked
position to complete the installation.
Step 4: Put the CPU Fan and heatsink assembly on the CPU and buckle it
on the retention frame. Connect the CPU FAN power cable into
the JCFAN1. This completes the installation.

2.2 FANHEADERS
These fan headers support cooling-fans built in the computer. The fan
cable and connector may be different according to the fan manufacturer.
Connect the fan cable to the connector while matching the black wire to
pin#1.

IDE1: Hard Disk Connectors
The motherboard has a 32-bit Enhanced PCI IDE Controller that provides PIO
Mode 0~4, Bus Master, and Ultra DMA 33/66/100 functionality.
The IDE connectors can connect a master and a slave drive, so you can
connect up to four hard disk drives. The first hard drive should always be
connected to IDE1.
