CMOS error - bad checksum...defaults loaded

[RhysK]

Hi...Can anyone help me here. I'm getting the above message on boot up.
Also machine doesn't boot up at all sometimes. I tried removing the battery and replacing it after a few minutes, also rechecked the BIOS settings.

Any ideas ?

Pls help !!

Sounds like it doesn't like a setting in CMOS. If there is a modem in there, remove it and see if the error keeps coming up. Are you taking the defaults with your CMOS settings?

I've had that problem in past and new battery always solved it. Then I attempted to install an additional LPT and some more memory. Rebooted and got dreaded "cmos checksum error - defaults loaded" message. I tried multiple new batteries, rechecked cmos/bios settings, pulled LPT install, pulled memory, everything. But nothing helped. I even reflashed bios. After a point I said "screw this" and bought a new motherboard, which was an upgrade so no huge loss. Maybe you have a bad ROM chip... I don't know -- wish I did -- but I empathize with you.. http://www.sysopt.com/forum/frown.gif

Good luck!

Hi guys,

I suspected as much. I've pretty much tried everything. I think I'll just have to take the hit. It looks like I'll have to invest in a new motherboard.
Thks for all yr suggestions anyway.

thats a common problem even with new motherboards. it usually fixes the problem is you do a bios update so before youre ready to deep 6 your mobo i would go to their site and try that first. worked for me on 2 seperate boards.
