Question about Biostar P4M80-M4 Motherboard
I am having problem with my CMOS Setting, it doesn't retain any setting and I have to reset the date and time everytime I boot my system. I've changed the CMOS battery but the problem still persit. I recently flashed my BIOS to see if it will help, with no result, however I was able to bypass the BIOSTAR page and now I have a warning on the start-up page and i don't know what to do. The message read thus:
CMOS checksum error- Defaults loaded
Warning! CPU has been changed or CPU Ratio changed fail.
Please re-enter CPU settings in the CMOS setup and remember to save before quit!
Its due to your default CMOS setup does not match with your CPU configuration especially with CPU speed.

Make sure the battery has plenty charge or remove the battery for a while, about 5 minutes to see if that restores it some motherboards cmos batteries are soldered in
You could check the site for the machine vendor to see if there is a reset jumper.
If that doesn't work then you will need to refresh the BIOS
You should make sure that all of the BIOS settings in the system are correct, by rebooting the system, going into BIOS setup and double-checking all the values hopefully against a recent
If you have reset the CMOS memory you need to go into the BIOS setup screen and reconfigure the BIOS.
To do that you need to press a key while the computer is booting Usually the Delete or F2 but can be other keys
It should tell you on the bottom of the first screen which key to press to enter BIOS setup.
If you don't know the settings the should be one for optimal defaults - use that one.
You will also need to reset the time and date.
In the main or system setup screen you should be able to see the date and time Using your arrow keys navigate to the date and change the date. Once highlighted on the month, day, or year, press your arrow keys or your page up / page down keys to change the date.
Press F10 Save, Exit and re-boot and everything should then work
hope this helps
