Please don't forget to CC the coreboot mailing list. You could
determine the chip's layout by looking on it: it has a dot near CS
pin. As for cable/clip and programmer, check "Flashing BIOS chip with
Bus Pirate" article at dangerous prototypes forums: it has a good
review of SOIC8 test clips and also compatible with CH341A programmer.

I'm not 100% sure for the T530. Where do I find the layout of the two chips of the

which pins to connect, but I mean what cable/clip etc. do I need? What hardware do I need
