Is there any way I can wrangle support for the 25U4035 into the app? It's a 4mbit, 1.8V serial eeprom, but I can't find a pinout for it.

Macronix brochure was the only mention of it I could find and it was light on the details. These are common eeproms on Toshiba and Samsung HDD interface PCBs and rather than risking damage with heating the board to remove the chip, I'd like to do a reprogram with a clip to transfer firmware from one board to another.
