PCIe adapter for Dell DGFF laptop GPUs
A DGFF to PCIe adapter, based on my work on MXM Immobilizer (DGFF is just funny MXM)
Still extremely experimental and not anywhere near ready for use or testing DGFF pinouts taken from Dell Precision 7740 LA-H281P and Area51M LA-G881P boards The DGFF footprint's dimensions are unlikely to be accurate, it has been recreated from pixel measurements of a high-resolution image of a DGFF card. In any case they do not match the likely more accurate Framework Laptop 16"'s FXBeam footprint available elsewhere. This adapter is designed so far to work with Dell Precision and Alienware cards, their…
