RTX 3070 Ti VBIOS Reverse Engineering: mapping and analyzing GA104 firmware

RTX 3070 Ti VBIOS Reverse Engineering documents analysis of an MSI GA104 VBIOS, covering its ROM layout, NPDE and BIT structures, x86 BIOS, compressed UEFI GOP and Falcon fuc5 microcode. Its workflow combines ROM parsers, REA with Ghidra, EfiCompress decompression, envydis and a Falcon MMIO probe; the repository includes scripts, format notes and an envydis ISA patch.

Requirements & limits

Prerequisites: Requires a dump of the user’s own RTX 3070 Ti VBIOS; the repository includes no NVIDIA ROM or firmware blobs.
Prerequisites: The documented workflow uses REA, Ghidra, EDK2 EfiDecompress and envydis; its REA scripts target WSL.
Limits: The author reports that the encrypted Falcon HS block cannot be decrypted by static analysis; the MMIO debug test writes to Falcon registers and is documented for a bare card without a driver.
