Where is the chip that contains the EFI firmware on the MacBook Pro A1150

I recently purchased a MacBook Pro 2006 A1150. Once I received it I discovered the EFI Firmware is messed up! I can boot from disks but not the actual hard drive. However I burned a disk that allows me to boot from the hard drive through the disk (but only in safe mode) I purchased a piece of equiptment (Bus Pirate by Sandbox Electronics) to flash the original firmware back onto the chip. I received the Bus Pirate today and removed my logic board but I can't find the chip containing the efi firmware anywhere! I heard apple uses Atmel chips for efi but I'm not sure if that's on all macs. Anyway if anyone can help please do! Thanks, Matt

MacBook Pro, Mac OS X (10.6.8)
