Thanks Idwer for your response. I downloaded most public datasheets available for the CPU and the PCH (it was called 7 Series).
At this point I'm mostly interested in just identifying the flash chip without disassembling the laptop, although I'm ready for that if necessary. However, I do need to find a USB-based chip programmer that can do parallel, FWH and SPI. I still have to get a spare SPI flash chip and port coreboot to my Asus AMD board. For some reason I killed by home-built Willem PCB3B trying to convert it to PCB4-something to use newer version of its software.
