I think I see it. In the bottom-left there is a white fan header labeled
"SYSFAN4". Just northeast of that is the chip. Am I right?
I thought I was going to have to jerry-rig something messy to replace the
SOIC8 with a socket of some sort, but I see that someone found a source
of compact and relatively affordable sockets. The clearance with that
10-pin header just south of the firmware chip looks rather tight. I also
see some adapters that puts a socket on an SOIC footprint and then a DIP
adapter is plugged in.
