CMOS checksum error

[warfish]

I have an old P-150 that I overclocked to 166 by moving my jumpers on the mobo. Multiplier was 3 and the freq. was 50mhz
I changed those to 2.5 and 66mhz respectively. the machine starts to boot then hangs and tells me I have a CMOS Checksum error and that it has loaded the defaults. it makes me press F1 to continue booting windows. The machine seems to work OK thereafter. do I have to clear my CMOS or something else to iron out that kink? I have went through the bios setup but it still goes to the default settings after I save?

I would flash the BIOS with the latest version and then clear it and load the factory defaults.

Thank you for your reply, I already have the latest bios circa 1996 if you can call that a late model release. It's an old PC Chips 519 board and the **** thing won't die. I gave it to my 6 year old so she can surf what I let her see. I'm going to build her a new one later this year and thought I'd build a home network using the old machine as a basic file server.
