Hello Jake Lo,
I have created the text file PE32 IFR.TXT according to your instructions.
(I assume that this only serves to check whether the parameters for patching are correct. So if the value for DVMT is 0x432  is already 0x4).
Then I created the boot stick with grub and executed the command setup_var 0x432 0x4.
In the config.plist I then have the two patches:
framebuffer-fbmem
framebuffer-stolenmem
removed.

The directory /Library/Displays removed to.

nvram-reset and started it.
Unfortunately without success
Is there still a change to get the int. monitor running?

 

Desktop.zip

OK, i'll do so.

But how?

dxdiag shows 128Mb.

 

i copied the directory /System/Library/Displays to the directory /Library/Displays.
In /Library/Displays/Contents/Resources/Overrides/DisplayVendorID-4d10 I copied the attached file.
Now two monitors are displayed, but the int. one remains dark. The backlight on the int. can even be controlled. Also with the keys.
 

DisplayVendorID-4d10.zip

I also tried to create an appropriate configuration with the Hackintool. Unfortunately without success

is there another way to see how much RAM has been reserved for DVMT?

Thanks for the support.
I had already tried inserting the hex string.
Unfortunately without success.
I made the entry and of course nvreset (several times).
When I start without ext. monitor, now the int. screen stays on and shows the text outputs. After some time it darkens, but does not switch to graphics mode.
If I plug in the ext. monitor, the int. screen switches off and the login screen appears on the ext. display.
So it has already changed a bit. 

Desktop.zip

Thanks for the tips, but I have zero idea how to do this.
I installed Windows 10 and used Monifo to create the information for the internal display.
How can I now with the won infos the config.plist happy?
I would be grateful for any further help.

Moninfo.zip

how?

per kext in EFI?

or

per Vendordirectory in Library/Displays...?

or

per Vendordirectory in System/Library/Displays...?

 

i found only a script for external Monitors.

 

Hello Jake Lo,
I have now purchased a Precision 5510.
This has a UHD display.
With a monitor connected to HDMI, I was able to use your EFI at:

https://osxlatitude.com/forums/topic/15235-precision-5510-opencore-mojave-catalina-big-sur/?tab=comments#comment-107493

 

Install Big Sur.
I am thrilled how well everything works. I'm going to add a DW1830.
Unfortunately, I can not get the int. 4k display to run.
Can you give me a tip?

 

Hello Baio77,
do you think it is possible to enable the Thunderbolt port?
I have already enabled it in the BIOS.
I currently have a WD15 connected to the USB-C port.
If the TB mode works, I would get a TB dock.
The touchpad buttons don't work for me either.
I am running the Dell 7490 BigSur 11.5.1.zip from Jazzoo. (with changed serial and uuid's).

DW1830 ist integrated and work.

Hello Jake Lo,
here are the files you asked for.

Hello Jazzoo,
thanks for the tip with the 11.5. will wait.

 

MacBook Pro mit WD16T.ioreg VoodooPS2Controller.kext.zip

Hello people,
Jazzoo motivated me with the statement that the same chips are installed in the touchpad of the 7480 and 7490 to do the following:

I copied the VoodooPS2Controller.kext from the EFI for the 7480 to the EFI 7490, did a nvram-reset and rebooted.
Result:
Nothing changed with the touchpad. Pointer very slow and all buttons without function.
But now the USB ports and the NIC in the WD15 work.

Now only TB is missing and maybe soon there will be a solution for the touchpad and their keys.

Thanks again to all who supported me.

 

Hello people,
thanks again for your great support.
Especially quynkk5 I have to thank. Without the hint about the image at Olarila, I would not have even started the attempt.

With things running so nicely, I hooked up a Dell WD15 USB Type-c docking station.
Except for the USB ports and the NIC, everything works.
Is there a possibility to get this to run as well?

 

Hervé has worked out a great tutorial for this constellation and of course Jake Lo, who has helped me out several times.

 

If so I will get a touchpad from the 7480 as a spare part and install it in the 7490. A DW1830 is also already on the way.

 

Stay healthy

 

Hi,
have connected the HDMI monitor.
changed the value and restarted.
HDMI monitor remained dark.
Unplugged HDMI connector and plugged it back in.
Shortly after that the picture was there.
Funzt (is german for works)

many many thanks

now only Thunderbolt and the trackpad is missing, then I am happy
 

Here is the ioreg with HDMI

MacBook Pro von Birne HDMI.ioreg

fix work, thanks

Hello Jake Lo,
I have tested your EFI.
Result:
- Sound and microphone work.
- Camera works
- Trackpad works, but pointer is very slow despite max pointer speed.
- The touchpad buttons do not respond (all 4).
- Sleep mode works.
- Volume control works with F2, F3 and F4.
- Brightness cannot be controlled with (Fn) F11 and (Fn) F12
- Thunderbolt is not present

 

Thanks for your efforts

Hello Baio77,
have generated the data with your Debug-EFI.
Thanks for your time.

SysReport.zip

I have tested a little further.
a monitor connected to HDMI is not recognized.

Hello Baio77,
Thank you very much for your support.

Have now tried the following:

1. BIOS settings like: https://osxlatitude.com/forums/topic/11477-7490-bios-settings/?tab=comments#comment-90318
2. copied your EFI folder to internal SSD.
3. started
4. nvreset
5. started

Result: no sound, no touchpad, no sleep, no Thunderbolt

started another time with nvram-reset no success.

Does it make sense to do a complete reinstall with your EFI?

here still the ioreg with your EFI

MacBook Pro von Birne-Bajo77.ioreg

Hello Jake Lo,
thank you very much for the support.
I have tried all your values with a following nvram-reset. No sound, no microphone.
The trackpad doesn't work either, so I tried again the EFI folder without
(AirportItlwmBS.kext and IntelBluetoothFirmware.kext) uploaded.

Stay healthy

EFI Kopie.zip MacBook Pro von Birne.ioreg

Hello quynkk5,
I downloaded the Olarila image from again with another PC and installed it on the stick. Then copied your EFI folder from

- Dell E7490: https://1drv.ms/u/s!AmHnQsJK7vXsiVxAsbUX-ZV0l3BJ?e=O0K3XP

booted, did an nvram-reset, booted and waited.
And (big joy) installed Big Sur. with a USB mouse.
Thank you very much.

WLAN and BT have started working after one or two more restarts with nvram-reset.

Unfortunately, some things still don't work.
- sound
- microphone

- sleep

can you give me another tip?

hello to all contributors,
i have the same hardware as VRdP:
Dell Latitude 7490
CPU Intel i7 8650U Kaby Lake R 8. gen
GPU Intel UHD Graphics 620
Intel Dual Band Wireless-AC 8265

As described, I used the image from Olarila to populate the installation stick. Then I copied the EFI folder from quynkk5 to the EFI partition, did an nvram-reset and booted.
I lift the same error as described in the video of VRdP.
Disabling the voodoo components in config.plist does not bring success.
I have tried this with several different USB sticks.

Then I deleted the sticks, created with the terminal Big Sur installation sticks and copied again the EFI of quynkk5. Unfortunately with the same result.

Is there any other way to install Big Sur or Monteray on a 7490 (not E7490)?

 

Your update OC 0.6.7 works great. Many thanks.

This message is created from Bir Sur.
It was the config-HD520 that made this possible.
The config-HD520-Intel started but did not enable Bluetooth.
The startup process is faster than ever!
Now have an i7 
 

Many thank's again.

Bootloop. Nothing else.

Switched to the debug version of OC and set the debuglevel to 83.
After the start comes for a short time an error message "NVRAM..." then the installation of Big Sur starts and it is for a long time only the apple to see.
I have attached the logs from the EFI partition.

Hello,
have dabbled a bit in carabiner and rearranged the theme with the buttons for my needs.

After the conversion to OC, everything now runs as it should.
Thanks again for your help
Have now tried to update to Big Sur.
The result is the black screen with the white apple. (Even after hours no other picture)
I created a USB-Sitck with Catalina and copied the OC-EFI from here. Then i installed a new SSD and installed Catalina from this stick. Runs.

But no update to Big Sur is possible from here either.

Now I created a USB stick with Big Sur, copied the same OC-EFI folder into it. Also with this the installation is not possible.

What am I doing wrong?
