JUMPERLESS QUICK SETUP PROCEDURES
1. Insert the Pentium® II CPU correctly.
2. Plug in other configurations and restore the system.
3. Press <Del> key and switch on power to the system to enter BIOS setup.
4. Enter “CPU Speed Setting” Menu to setup CPU speed.
Note: If you don not set CPU speed; your system will run at the lowest setting
(133MHz for Pentium® II)
5. Save and exit BIOS setup, your system can now boot successfully.
JUMPERLESS CPU SETUP MENU
Select <CPU Speed Setting> item from the main menu and enter the sub-menu:

CHAPTER 3 CONNECTOR
CONFIGURATION
Once the mainboard has been fastened into system case, the next step is to connect the internal
cables. The internal cables are wire leads with plastic female connectors that attach to the
connectors. The mainboard connectors have varying numbers of pins and are the points of
contact between the mainboard and other parts of the computer.

3.1 MULTIPLE FUNCTION JUMPER
Multiple function jumper includes speaker, reset, keylock, harddisk LED, ATX
power switch,
Fig. 4a Multiple Function Jumper
•RESET – RESET SWITCH CONNECTOR
Attach the Reset switch cable to this connector. The Reset switch restarts the
system.
•POWER – POWER ON/OFF SWITCH
It is used to switch on or off the ATX power supply. The power is turned on by
short the power switch once. It needs to hold the power switch about 4 seconds
to turn it off when it has not start to display.
•SLEEP – HARDWARE GREEN CONNECTOR
Sleep is for SMI Break switch setting. When Sleep is trigger from Open to
Close and back to Open, the system would suspend immediately.
