(3)  CMOS RAM Clear (3-pin) : JP5 
A battery must be used to retain the motherboard configuration in CMOS RAM short  
1-2 pins of JP5 to store the CMOS data. 
To clear the CMOS, follow the procedure below: 
1.  Turn off the system and unplug the AC power 
2.  Remove ATX power cable from ATX power connector 
3.  Locate JP5 and short pins 2-3 for a few seconds 
4.  Return JP5 to its normal setting by shorting pins 1-2 
5.  Connect ATX power cable back to ATX power connector 
Note: When should clear CMOS 
1.  Troubleshooting 
2.  Forget password 
3.  After over clocking system boot fail

Chipset (or core logic) - two or more integrated circuits which control the interfaces 
between the system processor, RAM, I/O devises, and adapter cards.  
Processor slot/socket - the slot or socket used to mount the system processor on the 
motherboard. 
Slot (AGP, PCI, ISA, RAM) - the slots used to mount adapter cards and system RAM.  
AGP - Accelerated  Graphics  Port - a high speed interface for video cards; runs at 1X 
(66MHz), 2X (133MHz), or 4X (266MHz), or 8X (533MHz).  
PCI - Peripheral Component Interconnect - a high speed interface for video cards, sound 
cards, network interface cards, and modems; runs at 33MHz.  
ISA - Industry Standard Architecture - a relatively low speed interface primarily used for 
sound cards and modems; runs at approx. 8MHz.  
Serial Port - a low speed interface typically used for mouse and external modems. 
Parallel Port - a low speed interface typically used for printers. 
PS/2 - a low speed interface used for mouse and keyboards. 
USB - Universal Serial Bus - a medium speed interface typically used for mouse, keyboards, 
scanners, and some digital cameras. 
Sound (interface) - the interface between the sound card or integrated sound connectors and 
speakers, MIC, game controllers, and MIDI sound devices. 
LAN (interface) - Local Area Network - the interface to your local area network. 
BIOS  (Basic  Input/Output  System) - the program logic used to boot up a computer and 
establish the relationship between the various components.
