HP EliteBook 840 G1 & OpenCore Catalina/Big Sur

Hello anderson lima you need to make usb using the guide in the forum and then Copy the EFI to the USB Stick.

For BigSur use Beta 4.

And if it not work i give you my own EFI Folder!!!

Läuft bei auch Windows durch opencore?

vivandi I use the macos mojave on the 840 g1, it works well. however when I try to install big sur it does not start. I've tried all the ways. It only starts when I delete the SSDT IGPU.

I used all the EFI folders on the forum and none worked

Big Sur works on mine. Can you upload a picture of the error?

Raptortosh the error does not appear, the system starts to turn on and simply turns off.

but when I delete the SSDT IGPU patch it turns on normal, but without graphics, only 3M

Ok, I dont have that. Opencore is the newest? NVRAM reset?

Graphics Set in Bios? Only iGPU Notebook (Like mine)?

Raptortosh I need an EFI for hp elitebook 840 g1. i5-4300u, gpu HD4400, 8gb ram ssd 240gb, already tested all of the forum, but to no avail

Tbh. I have exactly the same One

Don't know if 256 or 240, but Not important.

This also doesn't work? https://www.hackintosh-forum.d…5-bs-hpeb840g1-oc060-zip/

Do nvram reset...

Please don't Post in Code Box...

I can upload the efi, Which i am using right now tomorrow...

Does Catalina work?

Raptortosh in catalina the same error occurs. but I can test with your EFI

Ok. Bios settings?

I will upload it tomorrow...

when i deactivate the multi-core cpu the system starts, when i activate it does not start.

If your BIOS Settings are correctly, this EFI should work for you! BUT you will have to add a Serial, after it works. For booting this is enough...

If you want to use Intel WiFi, you need Heliport... HeliPort.dmg.zip

With the Intel Wlan card he didn't boot for me either ... only with the DW1520 ... DW1550 for example.

I have Intel card, and it works. It detects my WLAN, but Not tested now...

my settings bios are correctly. I Will test this EFI!
i use Wi-Fi Atheros AR9565, works?
thanks!

my settings bios

Spam the F10 key

Go to Advanced

• Device configuration
  • Don't check Fn key switch (it has to be unchecked in order to the volume and brightness hotkeys work)
  • Change Video memory to 128MB
  • Disable wake on USB
  • Disable Virtualization Technology (VT-x)
  • Set SATA to AHCI
• Built in device option
  • Disable Wake on LAN

Save and reboot in UEFI.

CSM should be off too...
