It used to not be possible to mod this bios because there's no slic. Now with with the v1.26 phoenix tool I can directly choose D5150A07.exe downloaded from dell and use DELL.BIN as SLIC. It then asked me there's no complete slic and if I want use dynamic method. I answered 'yes' and it generated D5150A07_SLIC.exe successfully. Has anyone tested it and am I safe to flash the bios now? thanks.
