Slow to boot/Restart/Shutdown Better when dual booting with Win10/not sure why
Prerequisite:
Set DVMT to 96MB (0x3)
Source = FireWolf™s guide
Steps to change the DVMT value (Done on Windows or WinPE)
-
Universal BIOS Backup ToolKit 2.0.exe - to backup the BIOS (DellInc.-1.5.3.rom)
At time of writing - BIOS version 1.5.3
-
UEFITool.exe to find the module labeled Setup 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
-
Universal IFR Extractor.exe to extract setup.bin to a readable text file
-
Use notepad to search for “DVMT†in the text file, 2 were found at 0x432 and 0x433
Both with value of 0x1 but only 0x432 needs to be set to 0x3
-
Format a USB drive to fat32 and create a folder name EFI (SD Card works too)
-
Download the EFI Shell and extract the Boot folder into the newly created EFI folder
i.e.. /EFI/Boot/bootx64.efi
-
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 0x432 0x3
To verify, just enter setup_var 0x432 and hit enter, the value will be listed
Note: Settings will retain after BIOS update but will reset if you select "Restore Settings" in BIOS!!!
BIOS Settings:
Set to "Load Default", Apply, then set the following:
TPM = Disabled
Secure Boot = Disabled
UEFI = Enabled
SATA Operation = AHCI
Wake on Lan /WLan = Disabled
Enable Legacy Option ROMs = Enabled
(If Ethernet doesn't load, try disabling it instead)
