(3)CMOS RAM Clear (3-pin): JBAT
A battery must be used to retain the motherboard configuration in CMOS RAM short
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 JBAT and short pins
4.Return JBAT to its normal setting by shorting pins
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

2-3 Glossary
Chipset (core logic) - two or more integrated circuits which control the interfaces between the system processor, RAM, I/O devises, and adapter cards.
Processor socket - the 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).
PCI - Peripheral Component Interconnect - a high speed interface for video cards, sound cards, network interface cards, and modems; runs at 33MHz.
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.
BIOS (Basic Input/Output System) - the program logic used to boot up a computer and establish the relationship between the various components.
Driver - software, which defines the characteristics of a device for use by another device or other software.
Processor - the "Central Processing Unit" (CPU); the principal integrated circuit used for doing the "computing" in "personal computer"
Front Side Bus Frequency - The working frequency of the motherboard, which is generated by the clock generator for CPU, DRAM and PCI BUS.
