Re: P4C800E Deluxe Motherboard Problem
A bad checksum can be caused by a flat or near flat BIOS battery. Replace the battery and set the date and time.
Also set the BIOS to the default setup, ie go to reload default settings, or remove the BIOS battery for 1/2 hour the insert the battery and set the Date and Time.

It is possible that your CMOS battery is low or your BIOS is having problems already. You flash your BIOS and see if it works. It is very risky though it something goes wrong it will make your motherboard unusable.
This errror coming from motherboard because your BIOS version is different as compare with new version, so download new BIOS for ASUS Intel 815E Chipset CUSL2-C from web site of ASUS there is detailed step of How to upgrade BIOS, you can upgrade BIOS by creating Bootble Disc otherwise you can Upgrade from OS.
I hope that this has been very helpful for you
If you are also experiencing a problem saving the date and time in the BIOS, then you probably need to replace the CMOS battery. Also, chech to see if the CLEAR CMOS jumper on the mobo is set in the correct position.
It's not you. Asus's program from the CD doesn't function as you might except. You'll need to download, ASUS Update V7.06.02 Install Program for Windows 2000/XP/2003 & 64bit Windows XP/2003 within Bios Utilities. And flash your Bios from a floppy. Than download the Bios version you want. Having trouble getting the file to unzip? Download again but this time choose a different site. Like (Global) instead.
