When you set up (Configure) the bios, when you click save settings and exit, it basically counts all the zeros, all the ones, all the bytes, all the words etc and creates a number called a checksum.
Now each time it boots up, one thing it does is to count up and compare. If there is a difference, you get a bad checksum error.
This is normally caused by the motherboard cmos retention battery (the shiney coinlike thing) getting weak or going dead.
You unplug and open the computer, look for the battery and copy down the number (usually 2032 or 2074) and go buy a new one.
You quickly swap them out and then boot to the bios setup (usualy press del to enter setup or press F2 , etc it will say on the first splash screen.
How to configure your bios
You will need to probably "load optimal defaults" make sure the hard drive (primary master) is set to auto defined, and cdrom (secondary master) set to cdrom and then auto detect drives . Confirm any other settings are correct and save settings and exit.
