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 2) UEFITool.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 Trackstick Scrolling Download and Install Karabiner Launch Karabiner/Preferences/Change key/Point Devices/CursorMove to ScrollWheel Enable MiddleClick+CursorMove to Scrollwheel Brightness Control Launch Karabiner/Preferences/Misc & Uninstall Under Custom Setting, click Open private.xml Replace file with the attached -> private.xml.zip Go back to Change Key Tab and select 'Reload XML' The new custom file will show on the very top call 'Remap Brightness Key' & 'Remap Volumes Key' Place the check marks there. Now Hit F11 & F12 for Brightness, hit F1, F2, & F3 for Volumes Control (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 Credits: FireWolf, Joe82, EmlyDinEsh, Bronxteck, Hervé, Rehabman, Piker-Alpha, Sontrg, toleda, Dr. Hurt, Clover Team, ...anyone involved with getting Broadwell supported
