Click Compile to check for errors, if no error, you can save the file with File Format: ACPI Machine Language Library, name DSDT.aml to /EFI/Clover/ACPI/patched/ (of HDD EFI partition)

11. Open Clover Configurator and import config.plist (in EFI partiton) and edit those values:

Following this guide to make my USB for my E6420. Will report on how it works since I have the NVS 4200M on my model. Been having issues booting up my USB. Will update this post once I try to reboot again

 

Edit: So far the install seems to be going alright and it boots fine. I'll upload the required stuff for those who run the nvidia model of the e6420 once I get everything working or at least a majority of it. This booted with injected nvidia for running the NVS 4200M

Just followed this guide to a T.. Ran into a small hiccup but was able to overcome with the dual link video....
I still appear to have a few problems maybe someone can help with.

 

- Cannot get the laptop to boot from itself without the USB drive.
  Get dell bios message that its attempted to boot into EFI ( its on LEGACY in bios )

 

In the post install directions it states the EFI partition will mount and to copy files but the partition never appears so I run "diskutil list " verify there is an EFI partition then I run the following commands :

 

[ mkdir /Volumes/efi ]

[ sudo mount -t msdos /dev/disk0s1 /Volumes/efi ]

 

Copy the EFI folder from the USB to the partition and finish the directions, Upon reboot it still only boots from USB and there is no sound or OSD.

 

The remaining issues are :

 

- NO Sound

- NO OSD 

Everything else appears to be working on my machine ( E6220 )

 

Any help would be greatly appreciated you guys rock!, I know its early but hopefully soon there will be a bootpack for EDP :)

in the zip there is a kexts and tools folder. open the tools and use kext wizard to install dummyHDA to S/L/E. dummyhda is in kext folder. then reboot and you'll have sound. use youtube to check if its working. i guess apple mustve taken out the ploop sound for volume control.
