This explains how to:
* Easily lower the voltage of an arduino
* Use that arduino to flash a coreboot image on a GM45 Thinkpad with a SOIC16 chip
 
It requires:
* An AVR Arduino at 5v
* An USB<->Serial adapter capable of providing enough current to power up:
** The arduino
** The flash chip
** The circuits around the flash chip
 
It was tested with:
* An arduino.org "nano version 3.3"
* A Ssparkfun "FTDI Basic 3v3" (Uses an FTDI FT232R)
