Can you leave a better description of the problem?, are you getting 'cmos checksum error' msg when you startup? If so, this is normal after removing the CMOS battery and replacing, it should only display error msg after 1st start then no more...

P4M900T-M2 Intel Pentium R dual CPU E2160 1.8 Ghz default BIOS Setting


The CMOS Checksum Bad Error during the pre-booting process only indicates that the CMOS battery is exhausted and it can not no longer save the current BIOS settings, Time settings and many more things.

The first and and the only way, according to me, to solve this problem is to replace the CMOS battery.

Please let us know, if this solution have helped you.

Hope this helps, Mrityunjay.

Cmos Checksum Error


Check CMOS and Memory Modules:::If the error message is "UNEXPECTED_KERNEL_MODE_TRAP," then it indicates you have problem with the memory of your computer. You need to check whether the SIMMs (Single Inline Memory Modules) are compatible and have the same speed. Secondly, also check whether you have set the CMOS (Complementary Metal Oxide Semiconductor) to the right amount of RAM. If these solutions do not work, you might have to replace memory in your computer....try to use system utility tool like Reginout.. Hope the problem is resolved.

Solutions to CMOS Checksum Bad Error

The CMOS Checksum Bad Error can be fixed easily by following the listed steps carefully.

CMOS Battery may not be functioning properly

If you suspect that your CMOS battery is not functioning properly, you can easily change it. Before changing your battery, reboot your computer to make sure that the error still exists. If it does, go into your CMOS and write down all of the settings. If all the settings are lost, you can usually retrieve them from your computer manufacturer. Now locate the battery and remove it, you might need to consult your computer's manual or technical support to remove your battery (the battery a flat, shiny silver colored and coin-shaped). Take down the CMOS battery's information such as volt, size, etc. Once you have your new battery, you can replace it and reenter your CMOS settings. If your battery was the cause of the CMOS Checksum Bad Error, you should have solved the problem.

Your BIOS may have been updated

If your BIOS have been updated recently, your CMOS settings may have reset. Make sure that the values entered in the BIOS are correct or simply reset them to the default settings. If you believe that a virus has updated your BIOS settings, run a virus scan and make sure that the BIOS settings are back to the default.

The Computer may not have been shut down properly

Sometimes when running MS Windows, if you shut down your computer without first properly shutting down your operating system, it will corrupt the CMOS settings causing the CMOS Checksum Bad Error. You can easily avoid this error by making sure that you completely shut down your computer properly before turning off the main power. Usually this entails going into the Start Menu, clicking on Turn Off Computer/ Shut Down. If improper shutdown was the cause of the error, you may have solved the issue.

Booting problem


There are usually three main reasons that a CMOS Checksum Bad Error has occurred. They include:
  • CMOS Battery may not be functioning properly. The battery life may have expired.
  • Your BIOS may have been updated (either by user or possibly a virus)
  • The computer may not have been shut down properly e.g. shutting off the computer's main power without first shutting down the computer (MS Windows requires you to shut down your computer before shutting off the power).
