Prerequisite:

Set DVMT to 96MB (0x3)

Source => FireWolf's guide

Steps to change the DVMT value (Done on Windows or WinPE)

 

1) to backup the BIOS (DellInc.-A10.rom):

Universal BIOS Backup ToolKit 2.0.exe.zip

    At time of writing - BIOS version E7450 A10

2UEFITool.exe to find the module labeled SetupPrep and extract the PE32 image section (setup.bin)

    Update

   For Dell Only: Search with this GUID then extracting the PE32 body under it would be faster /easier than finding the module per guide

          899407d7-99fe-43d8-9a21-79ec328cac21

3) Universal IFR Extractor.exe to extract setup.bin to a readable text file

4) Use notepad to search for "DVMT" in the text file, 2 were found at 0x15b and 0x15c

    Both with value of 0x1 and need to be set to 0x3

5) Format a USB drive to fat32 and create a folder name EFI (SD Card works too)

6) Download the EFI Shell and extract the Boot folder to EFI folder 

   i.e.. /EFI/Boot/bootx64.efi

7) Boot system with the USB and select UEFI Boot

😎 At the grub prompt, enter these commands, hit enter after each command, then exit and reboot

    setup_var 0x15b 0x3

    setup_var 0x15c 0x3

To verify, just enter setup_var 0x15b and hit enter, the value will be listed

Note: Settings retained even after BIOS update and no need to rerun again

         But will reset if you select Restore Settings in BIOS!!!

/!\ New Development: If you don't want to mod the BIOS as it might be difficult for some models, you could skip this step by adding 2 new kexts to /EFI/Clover/kexts/Other

Lilu.kext & Whatevergreen

 

Installation:

See here with Bootpack

 

 

Post Install:

 

Enable Brightness Control and Trackstick Scrolling

Brightness Control

  2. Under Custom Setting, click Open private.xml
  3. Replace file with the attached -> private.xml.zip
  4. Go back to Change Key Tab and select  'Reload XML'
  5. The new custom file will show on the very top call 'Remap Brightness Key' & 'Remap Volumes Key'

(Keyboards with same/similar layout will work with custom xml above too)

Note1: Personally use SmartScroll for Trackstick scrolling with Inertia. Don't really use Touchpad, 2 fingers scrolling and tap and drag does work.

Note2: Please use this beta version of ssdPRGen.sh for Broadwell system
