Troubleshooting CMOS checksum

During POST process, BIOS is capable to trace error on the system, usually when a error occurred, system will be issue a beep sound and comes with a message:


This article will only explain the error code for the system that using a BIOS type Award only. Please make sure first that the type of BIOS that you are use because each BIOS have different error code.

Error Code for BIOS Award
During this article was wrote, there is only one type of beep sound code and more than 40 types of error for the Award BIOS. One sounds a long beep followed by the two short beeps indicates that there is error in the video that the BIOS is not able to receive video signaling.

The Error message is a message that display on computer screen that is indicates error on the main system board. Among error message that is frequently encountered by users is the type of results to Add-Check (CMOS checksum error). CMOS checksum error problem is usually caused by the failure of the CMOS to get the decision right for the add-check in the BIOS.

Here are 4 types of CMOS checksum error code for the Award BIOS and descriptions:
Error Message BIOS Award


BIOS ROM checksum error - System halted

The add-check results on BIOS in the BIOS chip is not accurate, this indicates that your BIOS code has corrupt. To solve this problem, replace the BIOS with the other BIOS.

CMOS battery failed

CMOS battery does not work. Replace with new battery.

CMOS checksum error - Defaults loaded

Add-check Results CMOS does not exactly because the system had to fit the configuration of origin. Results may indicate add-check CMOS have been corrupt. This error may be caused by a weak battery. Check the battery and replace it with another if necessary.


Add-check Results CMOS does not accurate and a sign indicates CMOS have been corrupt. This error may be caused by a weak battery. Check and replace battery with other battery if necessary.

When examined the information on the schedule error message, the problem is checksum error is usually caused by weakness in the CMOS battery. To overcome this, you can replace battery with the new battery. Battery can be found at any computer accessories shop at the equitable price.

Blue Screen of Death [ BSoD ]

BSOD [ Blue Screen of Death ] or identified as a Windows stop error or BugCheck Code.. It’s a message error on the computer screen for some operation system specially Microsoft Windows.. Its display a blue screen which is when error system occur its can causes the system shutdown to prevent from excessive damage on the system.

You certainly have the feel the situation about this BSoD, maybe once in your life. This error usually occur when windows detects a problem or software error, hardware or software driver where windows can not continue the operating system correctly. This error is not caused by the 3 error above but the virus also can cause this BSOD.

Recognize BSOD

This BSOD is divided to 4 parts.

1. BugCheck information
Hexadecimal number together with “STOP” is called bug check code or stop code.. This is the important thing in BSOD.

For some bug checker, it’s brings to explanation what is happen or suggestion how you to finalize this matter.

Bug Check Symbolic Names

Every code for bug checker has a symbolic name individual.

Example above DRIVER_IRQL_NOT_LESS_OR_EQUAL is represent 0×000000D1 code

2. Recommended user action

Provides a list of proposal for treat or repair the error.

3. Drive Information
A part that have a contain details information about driver. If the hardware driver file or software is listed in this blue screen liability it’s a cause to BSoD.

4. Debug port and status information
Operation system will try to save system memory even to file that be found on hard drive or one of COM ports in this Stop error case. This part is give explanation about procedure.

Laptop Protection Tips

Laptops are more vulnerable damaged rather than the computer. Because of that we need to protect or “treat” properly so as its can be used any longer.

Do not let the new laptops we purchased a few months become damaged just because we are wrong to “treat” or protect.

We would need to refer to the following tips for a laptop to work on the maximum performance. Together with Computer Blog – Computer Tips, Guide, And Tricks
Do not bring a beverage or liquid with a laptop.
Do not put a laptop with a magnetic field source. Such as TV, Speaker Active, Radio Tape, or phone. Magnetic field will affect mainly the laptop hard drive components.
Keep Laptops into Beg provided
Do not move the laptop while still on
Use stavolt or stabilizer.
Do not lend laptops to anyone that you don’t know.
Install anti-virus and update periodically.
Shutdown properly.
Keep in a place with temperatures not too extreme
Do not disassemble the laptop itself (Ask for technician).
Clean the keyboard with a vacuum cleaner or air sprayed on the sidelines of the keyboard.
Be caution when opening and closing the laptop screen.
Hope you are beneficial from the tips above.

How to Break or recover the router password

Then Press the Break key or key sequence to put the router into ROM Monitor mode. The break key varies by computer or terminal software. The sequence might be CTRL-D, CTRL-Break or another combination.

At the > prompt, type 0 to record the current value of the configuration register normally 0x2102, or 0x102.


Configuration register = 0x2102 at last boot

Bit# Configuration register option settings:

15 Diagnostic mode disabled.

Type o/r 0x2142 to tell the router to boot from flash without loading the configuration in NVRAM at the next reload.

Type i to have the router reboot. The router ignores the configuration in NVRAM.

The router runs the setup dialog, Type no or press Ctrl-C to skip the initial setup Dialog.

Type enable ate the Router> prompt to go to privileged exec mode.

Copy the startup configuration to the running configuration by using the

configure memory or copy startup-config running-config commands. Do not type configure terminal. If you use the configure terminal command, you overwrite the configuration stored in NVRAM.

View the configuration by typing write terminal or show running-config. View the configured line, vty and enable passwords. Any encrypted passwords need to be changed.

Enter the configuration mode by typing configure terminal. Change the line of enable passwords as necessary.

All interfaces are in a shutdown state. Issue the no shutdown command on every interface that is to be used.

Type config-register 0x2102 to return the router to normal operation at the next reloads.

Exit configuration mode by pressing Ctrl-Z

Save your changes by typing write memory or copy running-config startup-config.

Reload the router and verify the passwords.

Improve System Speed

Follow Some Important Steps to speed the System
1.Let your PC boot up completely before opening any applications.

2.Refresh the desktop after closing any application. This will remove any unused files from the RAM.

3.Do not set very large file size images as your wallpaper. Do not keep a wallpaper at all if your PC is low on RAM (less than 64 MB).

4.Do not clutter your Desktop with a lot of shortcuts. Each shortcut on the desktop uses up to 500 bytes of RAM

5.Empty the recycle bin regularly. The files are not really deleted from your hard drive until you empty the recycle bin.

6.Delete the temporary internet files regularly.

7.Defragment your hard drive once every two months. This will free up a lot of space on your hard drive and rearrange the files so that your applications run faster.

8.Always make two partitions in your hard drive. Install all large Softwares (like PSP, Photoshop, 3DS Max etc) in the second partition. Windows uses all the available empty space in C drive as virtual memory when your Computer RAM is full. Keep the C Drive as empty as possible.

9.When installing new Softwares disable the option of having a tray icon. The tray icons use up available RAM, and also slow down the booting of your PC. Also disable the option of starting the application automatically when the PC boots. You can disable these options later on also from the Tools or preferences menu in your application.

10. Protect your PC from dust. Dust causes the CPU cooling fan to jam and slow down thereby gradually heating your CPU and affecting the processing speed. Use compressed air to blow out any dust from the CPU. Never use vacuum.
