Jumpers

Setting the BIOS Configuration Jumper

Always turn off the power to the computer before moving the jumper.  Moving the jumper with the power on may result in unreliable computer operation.

The diagram below shows the location of the Clear RTC RAM Random Access Memory. One of two basic types of memory. Portions of programs are stored in RAM when the program is launched so that the program will run faster. Though a PC has a fixed amount of RAM, only portions of it will be accessed by the computer at any given time. Also called memory. jumper.

Clear RTC RAM jumper (2-pin CLRTC)

This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time and setup parameters by erasing the CMOS RTC RAM data.  The onboard button cell battery powers the RAM data in CMOS, which includes system setup information such as system passwords.

1. Observe the precautions in "Before You Proceed".

2. Turn off all peripheral Any external device attached to a computer to enhance operation. Examples include external hard drive, scanner, printer, speakers, keyboard, mouse, trackball, stylus and tablet, and joystick. devices connected to the computer. Turn off the computer.  Disconnect the computer’s power cord from the AC power source (wall outlet or power adapter).

3. Remove the computer cover.

4. Short-circuit pin 1-2 with a metal object or jumper cap for about 5-10 seconds.

5. Move the jumper cap from pins 1 -2 (default) to pins 2-3 for about 5 to 10 seconds, then move the cap back to pins 1-2.

6. Replace the cover, plug in the computer, turn on the computer, and allow it to boot To start up a computer. Cold boot—restarting computer after having turned off the power. Warm boot—restarting computer without having turned off the power..  During the boot To start up a computer. Cold boot—restarting computer after having turned off the power. Warm boot—restarting computer without having turned off the power. process, hold down the <Delete> key to enter the BIOS BIOS, in computing, stands for basic input/output system. BIOS refers to the software code run by a computer when first powered on. The primary function of BIOS is to prepare the machine so other software programs stored on various media (such as hard drives, floppies, and CDs) can load, execute, and assume control of the computer. setup and to re-enter data.

Except when clearing the RTC RAM Random Access Memory. One of two basic types of memory. Portions of programs are stored in RAM when the program is launched so that the program will run faster. Though a PC has a fixed amount of RAM, only portions of it will be accessed by the computer at any given time. Also called memory., never remove the cap from the CLRTC jumper default position. Removing the cap will cause system boot To start up a computer. Cold boot—restarting computer after having turned off the power. Warm boot—restarting computer without having turned off the power. failure!

If the steps above do not help, remove the onboard battery and place a metal object or jumper cap again to clear the CMOS CMOS (pronounced "see-moss"), which stands for complementary metal-oxide-semiconductor, is a major class of integrated circuits. CMOS chips include microprocessor, microcontroller, static RAM, and other digital logic circuits. The central characteristic of the technology is that it only uses significant power when its transistors are switching between on and off states. RTC RAM Random Access Memory.

Though a PC has a fixed amount of RAM, only portions of it will be accessed by the computer at any given time. Also called memory. data.  After the CMOS CMOS (pronounced "see-moss"), which stands for complementary metal-oxide-semiconductor, is a major class of integrated circuits. CMOS chips include microprocessor, microcontroller, static RAM, and other digital logic circuits. The central characteristic of the technology is that it only uses significant power when its transistors are switching between on and off states. clearance, reinstall the battery. You do not need to clear the RTC when the system hangs due to overclocking.  For system failure due to overclocking, use the C.P.R. (CPU Parameter Recall) feature.  Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values. Due to the chipset behavior, AC power off is required to enable C.P.R. function.  You must turn off and on the power supply or unplug and plug the power cord before rebooting the system.
