Extract T430 Optimus NVidia GPU (NVS 5400M) Bios

[bryceadamprescott]

I don't need any modifications per se, but I'm having a hard time getting a usable VGA option ROM for the T430 NVidia GPU. I've used all the usual Coreboot repo tools and they don't seem to be able to find the VGA option ROM inside the firmware dump. I can get Coreboot to run fine via the Intel GPU but it somewhat obviously needs the option ROM for the NVidia GPU to make it usable. I've attached an unmodified dump of the firmware with the 8MB + 4MB chip dumps combined as a Dropbox link. I simply need someone with more experience than I to locate and extract the NVidia VGA option rom in this firmware dump.Thank you!

I was just wondering if you ever figured this out since I'm in the same boat.
