Yeah, best leave the heatsink attached. If you do remove it then you should clean off all thermal paste and apply fresh paste before reattaching it. But as I understand the intent of the R566 pads, they should be within fairly easy reach on the board, somewhere nearby the J27 PCIe Mini Card connector. > Unfortunately, I don't have a heat gun at hand to desolder the chip either, > so I'm considering just doing a dirty ISP and seeing where I can get. If the flash chip is SO-8 or SO-16, if you have another flash chip and if you only need to reprogram once (ie. you have a known-good coreboot image) then you could remove the flash chip by cutting its pins flush with the black chip package using a sharp nose side cutter, remove the black package with the chip, then desolder the pins one at a time, use solder wick to clean up the pads, and finally solder the second flash chip in - *after* programming it with a beaglebone, rpi or some other programmer.
