2.2 Installation Steps
Please follow the steps below to assemble your computer：
1．Adjust all jumpers onboard BPC-7934 according to the user manual.
2．Install memory;
3．Install other expansion cards.
4．Connect all signal line, cables, panel control circuit and power adapter.
5．Start the computer and finish BIOS settings.
Key components of this motherboard are Integrated circuit and these components
could be easily damaged by electrostatic influence. So, before installing this unit, please
always keep the following precautions in mind：
1．Please hold the board by edges and don’t touch any components or plug and socket pins.
2．Wear anti-static gloves/wrist strap while touching the integrated circuit components, such as
CPU, RAM, etc.
3．Put those unused or uninstalled components in static shielding bags or trays.
4．Please first check the power switch is off before connecting the power plug.
2.3 Memory Installation
Board with 1x DDRⅢslot. Note the following two points when installing the memory chip：
1．During installation, align the notch of the memory chip with the notch of the socket, and then
insert it firmly.
2．When selecting a memory chip, you must select a memory chip that supports this
motherboard specification.
2.4 Jumper Settings
Please refer to following instructions to do jumper settings before installing the
motherboard.
Remark: How to identify the PIN1 of all jumpers and interfaces: Please observe the word
mark on the side of the plug socket, which will be a “1” or bold line or triangular symbol; And
please look at the back of PCB, each with a square shape will be the PIN 1; and all the jumpers’
PIN1 have a white arrow on the side.
2.4.1 CMOS Clear/Hold Jumper Setting（JCC）
CMOS is powered by the onboard button cells. Clear CMOS may lead to permanent

elimination of previous system settings and make the system back to the original settings
(factory default).
Steps：（1）Shut down the computer and disconnect power supply；
（2）Make the jumper JCC Pin1 and Pin 2 short for 5~10 seconds（Pin1-2）and then
make it back to default setting with Pin 2-3 connected；
（3）Start the computer and press <Del> to enter BIOS setup, then reload optimal
defaults；
（4）Save and Exit
