    I have a 486 mother board. When I boot up into DOS I get a message saying, CMOS BATTERY LOW. How do I replace it.

    Crack the case open and look for it. THe older ones on 386 and 486 motherboards were some times integrated into the BIOS so you might be out of luck. Others had a small black pack that looked like 4 AAA batteries connected together and a red/black set of wires running to the motherboard....you can still get those.

    Do you mean 486 as in a 486 intel processor? If so, theres an easy way to get a new battery: Dump that ancient beast! You can get a 500Mhz AMD k6-2 for a cool $400 dollars, max.

    Some people don't have $400 buck to spend and if you are trying to resurrect it for a fax server or something why not?
