Hi, guys.

As the update of 10.11.4, the HD 530 seems be fully working. For me, I try many settings like (Inject/intel, ig-platform-id) and patch in hd530 full works, but all fails for my HD 530.

I should miss a step of modifying the DVMT memory before installing the OS X. As mentioned in the forum, I need to extract the BIOS information first. I follow this post, HD 5500 on Yosemite.


I download the DELL's BIOS update. I'm not lucky. The extraction fails with the cmd "***.exe /writeromfile", "***.exe /writebinfile" and tool like 7z(Extract here), since there is no such kind of external argument provide by DELL.

Guys, how do you extract the DELL's BIOS information?
If you succeed of extracting the BIOS information, could you provide some guidance for me? It really appreciates.
