what is checksum errors - defaults loaded.

When I boot I often get this in the boot screen:

CMOS checksum error - defaults loaded.

Whenever I get this I go to BIOS and load BIOS default.
and I can reboot with no error, but I get this again and again later.
Anybody knows:
What is this?
How to fix this?

Do I need to get new BIOS?
Anybody knows where I can get Award BIOS for ASUS Mobo P2B-F?

I have this currently:
Award Modular BIOS v 4.51PG copyright 1984-98
ASUS P2B-F ACPI BIOS Revision 1008

Thank you very much.

More about what checksum errors defaults loaded
  1. Sounds like the power in your CMOS battery is low
    Replace it

    Blame the newbies not the technology
  2. How do I replace it?
    Is it it as easy as plugging in RAM or CPU?

    Where do I get the battery on CMOS?

    I have Pentium III 450 mhz slot1, Asus P2B-F without documents.

    Thank you very much.
  3. I see silver coin like thing on mobo, that says <DL 2032 + DURACELL>: This must be the battery for CMOS?

    Where can I buy this battery?

    Thank you very much.
  4. yes, you can get a battery in spares, you will get it at almost any computer shop.
