hi to all, this is my first post and urgently hoping for some advice/help please

recently won an item on ebay sony vaio pcg-gr200 series with a bios password (new about this as it was cheap) but after looking through various pages of info i have discovered this password is retained in the eeprom, i have done basic electronic work in the past with the 12c pic in the past with the first ever model of playstation and my elvis programmer
(SHOWS HOW LONG AGO THAT WAS) anyway i am quite willing to give this ago if my elvis is capable of handling this kind of work however i,m fairly lost as to which software and hex or bin files i should use and the procedure.

any help in this would be gratelly apprecieted
