glebanych Posted July 27, 2016 Share Posted July 27, 2016 The boot issue was totally my fault. The thing is that i had Sierra beta installed before, with EFI volume (configs, kexts, etc). Every time i tried to boot newly installed 10.11.6, Clover used that config and those kexts. That's because I forgot to erase the EFI (or at least I could use F12 key to boot Clover from USB with 10.11.6). As for audio- yes, I have installed both kexts using KextUtility (i guess it fixes permission and do the things with cache) UPDATE: Used a different kext. Sound is working now!

shakeyhome Posted July 31, 2016 Share Posted July 31, 2016 Hi, I've got a very similar laptop, also a Dell 5558, but I'm having issues getting started. Perhaps the wrong version of the bios? I'm trying to set the video startup memory After some trying I was not able to find the setup key in the bios that was described. I finally managed to get booted to EFI and setup_var isn't recognised as a command. I'm on bios version A10. Has anyone else had similar issues? Got the efi shell:) now looking for the variable name to set video memory Got it! I found reference to 0x15b and 0x15c, tried both, 0x15c left the system unbootable, I think that must be just for dedicated graphics, I only have the Intel. got it up running and 0x15b set at 0x3. Windows reports 192mb but I confirmed 0x3. ) Wish me luck, haha Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted August 12, 2016 Moderators Share Posted August 12, 2016 are you using this ? ig-platform-id 0x16160002 try switching to ig-platform-id 0x16260006 Link to comment Share on other sites More sharing options...
elnino1981 Posted August 13, 2016 Share Posted August 13, 2016 Hmm, I tried switch that number to 6 and system has booted fine, but still without sound thru HDMI. I am using now this patched kext stored on my S/L/E folder https://www.dropbox.com/s/5y0cl2k3w8sicya/AppleHDA.kext.zip?dl=0 Or sound over HDMI not depends on this kext?

Administrators Hervé Posted August 13, 2016 Administrators Share Posted August 13, 2016 HDMI audio is handled through AppleHDA (patched for your own codec) + Intel framebuffer (patched BDW FB in your case). Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted August 13, 2016 Moderators Share Posted August 13, 2016 Not just the 6, the 2 as well = 0x16260006. If that still doesn't work, then you'll need to patch the FB as Hervé advised. Link to comment Share on other sites More sharing options...
elnino1981 Posted August 13, 2016 Share Posted August 13, 2016 Thank you guys, switched to 0x16260006, system booted fine, but does not helped in my case, so I will have to look how to patch Intel frame buffer. Please If you have a link where I can find some guide for my Hardware, it will be helpfull for me. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted August 13, 2016 Administrators Share Posted August 13, 2016 For the HDMI audio patch, all that's required is to modify the HDMI output connector-type from its default value of 00 04 00 00 to 00 08 00 00. This patch is applicable to all systems whatever the frameBuffer (SNB, Capri, Azul, BDW, etc.) and for all versions of OS X. So, you need to identify the HDMI port line in your particular layout-id of the Broadwell framebuffer (kext BDW FB) and then apply the binary patch; this can be done "on-the-fly" through Clover or through direct binmod of the FB binary file itself.
