Renaming of B0D3 makes the system unbootable. I patched everything from vanilla to what I had before and up to the renaming it works well.

The patch itself has to be applied to SSDT.dsl and SSDT-10.dsl. It creates errors and after I rename the residual 4 B0D3 entries manually it compiles but the system won't boot up. It hangs until the forbidden sign appears.

Renames must be applied equally across all DSDT + SSDTs.
Also, keep in mind DropOem=true required with patched SSDTs in ACPI/patched.

Boot verbose, attach photo. Attach EFI/Clover folder as ZIP (not EFI folder, press F4 in Clover prior to collecting). Please strip Clover/themes before compressing as ZIP.

You mean I should break it again?

You must provide the files that demonstrate the problem. Otherwise, I have no idea what you're doing wrong.
 
I managed to get more or less everything working except the WiFi that will be replaced this week. One USB port was dead after installing the files but RehabMan's USBInjectAll kext made them all working again.

Good news also the WWAN module is detected as "Dell Wireless 5809e Gobi‚ 4G LTE Mobile Broadband Card".

So to sum up, working:
  • GPU and Screen w/ Brightness / Resolution / Acceleration, all there, patching the DVMT is a must
  • Sound fully supported
  • Onboard Ethernet
  • USB
  • 4G LTE Module, need to learn how to use it
  • Webcam
  • SD Card Reader
  • Battery, status, sleep, display dim
  • Keyboard with FN
  • Trackpad and Trackpoint whereas trackpad does not support click&drag
Not working:
  • Fingerprint reader
  • Smart card reader (never tried)
One general problem are the early reboots that obviously occur due to memory problems. So quality modules and always used Slot 1 help. Even then 3-4 reboots are "normal" before the boot process starts properly. But sleep/wake works as designed.

Thanks again to RehabMan for the great support!

If your memory tests ok with memtest86, then your problem is elsewhere...

Real early reboots are typical for Haswell but not Broadwell, right?

No problem with correct Clover/BIOS setup.


Your profile has no laptop in it. Please fix.

Please provide complete details in your profile/signature
(Profile/Settings link in upper right corner of this site)

Mobo: manufacturer/model + bootloader(Clover/Chameleon/Chimera)
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
Mobo: HP ProBook 4540s (Clover)
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx), and graphics capabilities. For a laptop, these details are important and affect critical installation procedures.

Note: When specifying your bootloader, if using Clover legacy, please be sure to specify "Clover legacy"). Specifying "Clover" will be assumed as "Clover UEFI"
