_______NNNNOOOOOOOOOOOO!!!!!!!!!!!!!! _DONT_ DO THIS!!!!!

RESETTING THE BATTERY BACKED UP CLOCK NOT FOUND ERROR:

1) Make sure you have WB1.3.2
2) Open a cli
3) type:
          setclock reset
4) hit return
5) start preferences and reset clock

There. Isn't that nicer than shorting out your mother board?

Hope I got there in time :-)
