Step 9. Connect the Keylock (keyboard lock) Switch
Most computer chassis will provide a keylock switch. Normally, connect the marked
keylock connector to this motherboard’s keylock connector. This will cause the
keyboard out of function once you switch the keylock to “Lock.” This will prevent any
un-authorized keyin. The onboard keylock connector is a 5 pin pin-header. (See
reference information in the Chapter 3—Hardware Installation for detail pin assignment)
If the chassis does not provide the switch, you can skip this step.
Step 10. Connect the Speaker
Connect the speaker to the motherboard’s speaker connector. (Normally the red cable is
+5V power) (See reference information in the Chapter 3—Hardware Installation for
detail pin assignment)
Step 11. Connect the Power LED
Most computer chassis provides a power LED to identify if the system is on or off.
Connect the power LED to the 2 pin pin-header motherboard’s LED connector.
(normally the red cable is +5V power)
Or connect to the left side of onboard keylock.
Step 12. Connect the Devices LED
Some computer chassis provides device LED (Like HDD LED) to identify if the device
is under working or not. Connect the device LED to the motherboard’s IDE device LED
connector. (normally the red cable is +5V power)
Step 13. Connect the Power Input
This motherboard provides two standard AT power input. Carefully plug the P8 and P9
connectors from your AT power supply to the motherboard.
Step 14. Connect the Keyboard
Follow the keyboard cable’s key direction and connect to this motherboard.
Step 15. Plug the Display Card
Finally, insert the display card you have in horizontal direction into the PCI/ISA
expansion slot.
Step 16. Power on the system & Load the BIOS Default
Once the system is power on, on the lower left corner of the screen will show ”Press
DEL to enter SETUP, ESC to skip memory test.” Then press “DEL” to enter BIOS
setup for the first time power on and choose the “LOAD SETUP DEFAULTS” then
BIOS will responds “Load SETUP default(Y/N)?”, press “Y” and “Enter.” Finally,
choose “SAVE to CMOS and EXIT (Y/N)?” by pressing “Y” and “Enter.”
