No not fibs - it was personal experience. However, I did have my wires
crossed (so to speak).
To clear the CMOS in the original manual, the instruction was to cap the
CLR_RTC pins with the power on and battery in place. This blew the diode.
The revised instructions were to remove the battery and power and then cap
the pins. (Pity the revision came out after I'd RMA'd 2 boards though :-)
