Using the latest RBE and MPT, as well as the Flash Tool 3.04+, if I make even the smallest change in the BIOS, the card does not work. I can flash it back to the stock BIOS without problems and then it works fine. Running everything as Administrator. If I load the BIOS into the Editor and simply rename it, it works fine. Was there a change in the BIOS chip capacity? The card responds to all other adjustments and seems to operate properly.
