Nice trick for KCMA-D8/KGPE-D16 flashing (libreboot/osboot) and no DIP8 chips available to buy: solder SOIC8 onto SOP>DIP adapter. Put 2.54mm headers in breadboard, chip+adapter on that, and solder (breadboard keeps pins straight).
Slot into DIP8 socket. I do it all the time!
You *can* also just flash the default 2MiB chip (on D8/D16); remove it, put it in breadboard and flash, but I always upgrade the default 2MiB flash to 16MiB. I'm doing a KCMA-D8 for someone.
