You can try clearing the CMOS.  Every motherboard I have used provides 
either jumper pins or solder dots that can be shorted for that purpose. 
  You may go blind finding it, but if it's there it's labelled something 
like "Clear CMOS".  You will naturally want to *unplug* the computer 
before doing any poking around.

Another poster (George MacDonald) has pointed out that a labelled short 
point may not exist and in that case, the only thing you can do is to 
take out the battery, short things randomly, and hope for the best.  I 
actually don't know why removing the battery and shorting "it's" 
connector wouldn't be guaranteed to work.  If George MacDonald is 
reading this, maybe he can answer that.
