Hey guys, I'm trying to flash an IBM M5016 (LSI SAS2208 based) to IT mode, I tried multiple instructions and multiple firmware on it but I get other errors every time, this is one of them, I know that is basically says the firmware isn't Compatible. But I can't find an IT Firmware for the M5016 (I guess there is none), I know there is a way to let the firmware think it's an 2308 based controller but I don't know how I take any advice I can get, maybe I'm missing something (or I'm just to stupid to do this)
