the i2cBus http://www.mcc-us.com/techsrc.htm
14 PIN VERSION 24rf08 http://www.rebios.net/pad/bios9.htm

step3 a. download the r24rf08  from  ALLservice, and make the interface  (look the destnation folder C:\ALLservice\24RF08 the simple-i2cprog.pdf  is the interface, with reader software)

 

 

step4 use only the GNL , SCL ,SDA pins from the atmel 24rf08 and do the same reading way like jaa axx say,when your laptop boot and ask for the password plug the GNL, SCL, SDA pins with interface  and run from second pc the reader software r24rf08.exe .

(Don't unsolder the 24rf08 from the motherboard)
