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

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.
