I just change the FB value from 3 to 4. You can read more about it here.

Here, this will get your SDCard reader working too. Enjoy! AppleSDXC.kext.zip

What OS are you running, I'll send you my patch to test.

Use the bootpack but replace the DSDT in /Extra. No need to run my fix when replacing DSDT

Try replacing with this dsdt DSDT.aml.zip

Follow this guide. There's a patched dsdt for nvs4200m. HDMI video and audio works with nvs4200m.

Use Clover Configurator or EFI Mounter to mount the EFI partition. For sound, you need to install it to SLE.

Looks like you're trying to install Yosemite. Add nullcpupowermanagement.kext to EFI/Clover/Kexts/10.10/

This is for Yosemite Final. Install to SLE to work. To get HDMI Audio to work, you'll need to patch the DSDT. Get latest version from my guide. Also need to patch FB. This is for Yosemite. Mavericks version is also in my guide. See signature below.

No, you need a patched AppleHDA for sound. Get the latest one here. Speaker and headphone works!

You'll find it in my guide for E7440 with Yosemite when i create one.

Try this perl -pi -e 's|pci14e4,16bc|pci1217,8221|g' /System/Library/Extensions/AppleSDXC.kext/Contents/MacOS/AppleSDXC

Here you go. 10.10 Final

See here.

See my guide for E7440 below for new update

Yes, use patched kext from my guide. Look under updates for version of OSX. Layout-id is 12. sample below: Method (_DSM, 4, NotSerialized) { Store (Package (0x0c) { "built-in", Buffer (One) { 0x00 }, "layout-id", Buffer (0x04) { 0x0C, 0x00, 0x00, 0x00 }, "PinConfigurations", Buffer (0x00) { 0x00 } }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) }

See guide by pokenguyen starting at step 14. He's included a bunch of patches for this model.

You'll need a new GenericUSBXHCI for Yosemite. Should fix the webcam too.

Follow this guide and boot pack for Mavericks. You just need to replace the SSDT.

Which version of OS X are you trying to install?

Can't take any credit here. I just use your patches and Mirone's HDAPatcher to update it.

Replace the FB with the version for 1366x768

Thank you for confirming v2.8.7 works. Did you have to modify the info.plist?

This is a good starting point.
