hshamsaldin 2 Posted December 18, 2020 Share Posted December 18, 2020 (edited) Here is my OpenCore 0.6.4 EFI with modified ACPI-files and config.plist to work properly with HP EliteBook 840 G1. ## Changes: With Rehabman's SSDT-patches and kexts. You should boot OpenCore normally, but i have made very important changes to the ACPI-files and config.plist to make it as close to "Apple Like" as possible to fit the OpenCore mood. * Removed ~~SSDT-HDEF and SSDT-HDAU audio patches from SSDT-8x0G1h.aml~~, and Applies AppleALC audio injection, you'll need to do your own research on which codec your motherboard has and match it with AppleALC's layout. [AppleALC Supported Codecs](https://github.com/acidanthera/AppleALC/wiki/Supported-codecs). * Replaced ~~IGPU.aml~~ With PNLF.aml for backlight controls to work properly with OpenCore. * Removed ~~unnecessary config.plist patches that are made for other motherboards, like HP-840-G3~~. * Removed ~~SSDT-USB-8x0-G1 and USBInjectAll.kext~~. Reason for this is USBInjectAll.kext is no longer being maintained and the USBMap.kext version is how real macs USB map. [USBMap](https://dortania.github.io/OpenCore-Post-Install/usb/intel-mapping/intel.html). ## What Works: - **UEFI booting via OpenCore** - **Dual Boot with Windows/Linux** - **Built-in keyboard (with special function keys)** - **Built-in trackpad (Multi-Gestures)** - **Native WiFi & Bluetooth via Broadcom DW1560 BCM4352** - **HDMI Audio/Video with hot-plug** - **Native USB3 with AppleUSBXHCI using USBMap (USB2 works also)** - **Native audio, including headphone** - **Built-in mic** - **Built-in camera** - **Native power management** - **Battery status** - **Backlight controls with smooth transitions** - **Accelerated graphics Intel HD Graphics 4400** - **Wired Ethernet** - **App Store** - **iMessage & Facetime** Feel free to visit my GitHub repository for more detailed informations: https://github.com/hshamsaldin/OpenCore-HP-840-G1-Haswel EFI.zip Edited December 18, 2020 by hshamsaldin 1 1 Quote Link to post Share on other sites

Col_W 0 Posted January 25 Share Posted January 25 Hi, I have been trying to get this working on my HP 840 G1 with i7 and Intel/AMD graphics. I have a working Clover 5119/Mojave install and wanted to switch to Opencore to fix the update issues I get with OS patches. With your config I get to the boot menu but when I select my OS X partition it goes black for a second and then back to the menu. I can get the UEFI shell to open fine and I can also choose my Windows 10 partition which boots fine. I also get an issue if I try and update to a later version of Clover. I have tried reading through the Opencore guide but I haven't had enough time to learn it all yet. Can you think of anything obvious I should check? Quote Link to post Share on other sites
Leon03 0 Posted January 31 Share Posted January 31 I will try the efi file in my 820g2 Quote Link to post Share on other sites
Leon03 0 Posted February 8 Share Posted February 8 (edited) I modified my config.plist according to yours, and it can work in my 820G2. and I migrate to OC 0.6.6. It seems work well. I don't know how to test, such as multi-Gestures,backlight control... Change: 1. remove XOSI in SSDT-HACK.asl, and add SSDT-XOSI.aml & SSDT-EC.aml. Otherwise It can't boot into windows 10. (BlueScreen with ACPI_BIOS_ERROR) Problem: 1. I can't use USB keyboard & mouse in OC GUI. (But if I boot OC from USB disk, the usb keyboard can work) 2.when I boot into windows 10, the usb keyboard and mouse can't work. how to solve this?

Leon03 0 Posted February 10 Share Posted February 10 update to big sur 11.2，seems OK Quote Link to post Share on other sites
Leon03 0 Posted February 14 Share Posted February 14 It seems that I make a mistake in my config. I didn't enable XOSI in config.plist. once I enable it, I still can't boot into Windows. Still try to slove this. Quote Link to post Share on other sites

According to How to Identify the Windows Version in ACPI by Using _OSI, add Windows 10 version info in XOSI function. Quote Link to post Share on other sites
