I have replaced the battery on the mainboard but the problem still exists on my P111 Win98SE system.
At startup I get the Message; "CMOS checksum error" press F1 to load settings or Del to enter CMOS. selecting F1 starts windows OK but after shutdown and startup again the problem still exists. The timing is way out too and I beleive the battery to be a good one.
after checking out seedie's suggestion you could try resetting the bios to the default setting,making sure that you enable Plug and Play.If you do change to default values,you may want to note what you have set up incase of returning to same.
Is it possible that you have made changes to the bios setup prior to your error?
Thanks Jim, I reset the battery after checking it and restarted, the message I got was; "CMOS checksum error - Defaults loaded" click F1 to proceed or Del to enter CMOS. I clicked F1 to accept the Default settings and went into windows. I restarted the computer and it loaded OK so I am guessing that it might have been that the battery wasn't properly seated.
I think I am Ok now so thanks for your input.
