Nbssss successfully unbricked his ASUS G74SX laptop using the Bus Pirate. He used a Pomona 5250 SOIC clip to attach the Bus Pirate to the offending BIOS chip while it was still soldered to the board.
For those attempting this in the future, what worked was to connect the four signal pins to their counterparts (CS, MISO, MOSI, CLK), Ground to Ground, and also Vcc to 3V3, and disconnect the AC power and remove the laptop battery.
