Hello all!

 

This is the guide I am following:

https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-precision-clover-guide/&do=findComment&comment=54632

 

I've been toying with this E5450 for a while now and have finally gotten some progress, turns out I was an idiot and didn't configure the Bios properly:

 

(I missed this)

2. Press F2 to configure the BIOS

  • Sata Operaton -> AHCI
  • Secure Boot -> Disabled
  • Boot List Option -> UEFI. 
  • Enable Legacy Option Rom
  • Apply and Exit

So now I am getting I'm getting past the initial loading but it bombs out with this kernel panic:

Some notes: 

Boot pack - 

I used this one:

Broadwell - (See Note2 below)

   zip.gif  E5450_HD5500.zip   418.94KB   442 downloads

Updates:

I followed note to check for updates and replaced this kext:

E7x70, E7x50, E5450, Precision 7510

zip.gif  AppleHDA_ALC293.kext.zip   13.26KB   385 downloads

 

Anyone have a red hot clue what I did wrong? :) 

 

Thanks for reading. Eternally grateful :)

Yup, you must've missed the note from the bottom of the guide. Follow my E7450 guide Prerequisite section.

 

:excl:   :excl: Note2:

Systems with Broadwell / Skylake / Kabylake CPU such as Latitude E7450 and Inspiron 5548, you'll need to set the DVMT prealloc to 96MB in order to bypass KP and to enable full graphics with full QE/CI. For more info, see here.

Okay so!

 

This is my PE32 image's DVMT entries:

And this is what my sys showed for allocated video mem:

So Based on firewolf's article, my understanding is that I want to do the following with the GNU GRUB bootable editor:

setup_var 0x15b 0x4

setup_var 0x15c 0x4

(as my dedicated is 128mb)

 

Problem:

The setup hangs as soon as the load bar appears. It stays there even after a 1/2 hour. 

 

I also for fun tried 0x3, 0x2, 0x5 but no luck. If I put it back to 0x1 then the bar loads again and panics at the same place as before.

 

Any ideas where I messed up? 

 

Thanks again!
