EFORE YOU START
Thank you for choosing our product. Before you start installing the
motherboard, please make sure you follow the instructions below:
Prepare a dry and stable working environment with
sufficient lighting.
Always disconnect the computer from power outlet
before operation.
Before you take the motherboard out from anti-static
bag, ground yourself properly by touching any safely
grounded appliance, or use grounded wrist strap to
remove the static charge.
Avoid touching the components on motherboard or the
rear side of the board unless necessary. Hold the board
on the edge, do not try to bend or flex the board.
Do not leave any unfastened small parts inside the

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.
6
G41D3+/G41D3G+
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 CPU_FAN1. This completes the installation.

2.4 CONNECTORS AND SLOTS
FDD1: Floppy Disk Connector (Only for G41D3+ V6.0/6.1)
The motherboard provides a standard floppy disk connector that supports 360K,
720K, 1.2M, 1.44M and 2.88M floppy disk types. This connector supports the
provided floppy drive ribbon cables.
234
G41D3+/G41D3G+
IDE1: Hard Disk Connector
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 connector can connect a master and a slave drive, so you can connect
up to two hard disk drives.

PEX16_1: PCI-Express x16 Slot
- PCI-Express 1.0a compliant.
- Maximum theoretical realized bandwidth of 4GB/s simultaneously per
direction, for an aggregate of 8GB/s totally.
- PCI-Express supports a raw bit-rate of 2.5Gb/s on the data pins.
- 2X bandwidth over the traditional PCI architecture.
This motherboard is equipped with 2 standard PCI slots. PCI stands for
Peripheral Component Interconnect, and it is a bus standard for expansion
cards. This PCI slot is designated as 32 bits.
