HP Elitebook 8440p (Intel HD Graphics) the forgotten one Help creating DSDT

2 posts in this topic

Recommended Posts

Hey every body ...

i know the title is weird but really thats true !!

this model is forgotten among all this laptops here specially the hp

i know it is not the most power-full laptop but at least u can buy it for a great price and its compatible with OS X ... actually EliteBooks & ProBooks are very compatible with OS X..

any how i am seeking help for creating a DSDT for this model ( and later to patch audio for it) 

i hear you you will tell me there is already a DSDT for this model...!!!

but no the real thing is there isn't...

the one available DSDT is for (NVS100) graphics where i have (Intel HD Graphics).

am here talking about this :

 

Intel Core i5 520M

Intel HD graphics..

IDT Audio or HDA  Device id= 111d7603

 

I wanted to make a DSDT for this model and i started but i was forced to quit because DSDT creating needs PATCH as i found in the guides ... and there is no Patch available for this model at all ...

and i am looking forward setting mavericks on it but when i solve all problems  on 10.8.3

so please every body help me to create that DSDT as  i experienced CMOS reset and read that some functions might brick the laptop 

i am all listening and i have the tools 

 

Appreciated 

thank you :)

      Catalina update 10.15.4 without issues, make sure you update your kexts before hand and clover 5107
      Catalina update 10.15.3 without issues, make sure you update your kexts before hand.

      Catalina update 10.15.1 without issue although you may have to make sure clover boots from the right partition.
      HP 840 G2/G3, working with OS X 10.15 Catalina, for this to work you will need the SSDT-ECUSBX.aml and place that  EFI/CLOVER/ACPI/Patched. 
      Make sure you remove Remove all patches about renaming acpi of EC or H_EC, revert all ACPI renaming in ACPI DSDT.
       
      My method to install OS X on the SSD from a working real Mac via SSD to USB converter. I then install Clover and add my kexts and set the config.plist

      Keyboard backlight - controlled though BIOS anyways
      touchpad - using VoodooPS2Controller
      USB3 - this laptop has two on board only and I haven't test them using the docking station
      USB3.1 C
      Ethernet - using IntelMausiEthernet
      Sleep - kind of, closing the lid doesn't go to sleep but goes to sleep over time.

      After Testing:
       
      Graphics card: NVIDIA K1000M / K2000M / K2100M / K3000M / K3100M / K4000M / M1000M (ordinary TN1600x900 or 1920x1080), AMD W5170M / W7170M (DC2 or 4K), Intel HD4000 (ordinary TN1600x900 or 1920x1080) can be driven normally, but NVIDIA graphics card Brightness adjustment is disabled. AMD W5170m and w7170m are the best choices on 8570W and 8770W. The brightness can be adjusted normally and the graphics performance is very good. For WX7100m and WX4170m, the graphics card fans cannot be controlled, and other methods are required to control the fans. CPU: 3rd generation Intel Core i3, i5 and i7 (Ivy Bridge architecture, including all dual-core and quad-core. Celeron and Pentium are not supported), frequency conversion is normal. In general: If you have 8570W, 8770W, and hope you can get the best Hackintosh experience, it is recommended to replace the CPU with i7-3840QM / i7-3940XM, 8570W is recommended to choose W5170M, 8770W, and it is recommended to choose W7170M. In addition: If you want to have a 4K experience or perfect HIDPI, W5170m / W7170M supports 4K output, you can choose a suitable 4K screen to replace, but because 4K screens are mostly edp interface, and 8570W / 8770W motherboard is lvds interface, This requires a custom screen cable, which seems to be a difficult choice, but you can choose to do it yourself or buy it separately. In China, taobao.com is almighty and may be more suitable for you than eBay.
       
      EFI features:
      out of the box, the relevant hardware can be driven after the OS is installed, and it is easy to use without code operation.
      Supported models: HP EliteBook 8470p, 8570p, 8570w, 8770w (click the model for official specifications)
      Wireless network card: Recommended: BCM94360cd (requires ipex4 to ipex1,3 antenna 1300mbps), BCM94352HMB / DW1550 (2 antennas, 867mbps)
      Wireless characteristics: no white list, wireless network card with Bluetooth does not support the Bluetooth function of the wireless network card (also does not need to shield the pins), but the wireless normal use, you need the Bluetooth function to use this machine comes with Bluetooth:
      Clover version: 5103, keyboard mapping has been added Command key = Alt key, Option key = Win key
      Supported systems: macOS Mojave 10.14.6 (18G103)-macOS Catalina 10.15.x,
       
      Notes on known issues:
      1. The touchpad and the left and right keys under the touchpad are normal, the pointing stick and the left and right keys above the touchpad are temporarily unavailable (recommended to use the second generation of Apple Magic Trackpad)
      2. Indicator display problem (can be ignored, function is normal): Caps light is sometimes not switched in time, mute / wireless key may be yellow
      3.AMD graphics card / Intel nuclear display has supported sleep and 15 levels of brightness adjustment, NVIDIA has no
      4. If the AMD graphics card enters Huaping, refer to editing the Clover startup parameters, and add the Boot parameter radpg = 15 (the EFI file that has been configured with this parameter has been uploaded, refer to the following EFI-guided download link)
      5. Using the above NVIDIA graphics card with a normal TN screen 1600x900 or 1920x1080 can not enter the installation interface, please check whether the VBiOS of the graphics card is exclusively for HP, thank you for your test face K1000M
      6. Due to product design defects, the MSata positions of 8570w and 8770w cannot be used as boot disks, so EFI boot can only be placed on the main hard disk (turn the machine over and open the hard disk in the lower left corner of the cover, which is the main hard disk). Put on msata plate
      +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
      Hardware requirements:
      Model: 8470p, 8570p, 8570W, 8770W 1 or more, it is recommended to use another notebook for emergency Hard disk: It is recommended to choose an SSD hard disk of 240g or more. Samsung or Intel SATA hard disk is a good choice. Wireless card: BCM94352HMB, DW1550, BCM94360CD, miniPCIe slot U disk: 1 for 16g and above, another winPE emergency USB disk is recommended If you use a rescue USB flash drive, it means that you read this post carefully
       
      Make and install a USB flash drive:
      Get the mirror: please do it your way Making and installing a USB flash drive: macOS command line production is recommended, whether it is a real macOS model or a virtual machine (although this is not allowed to be discussed in many forums)Or you can choose to use TransMac or ether under Windows. This is not recommended, but it is simple enough for those new to Hackintosh. Make boot U disk: If you know how to put the boot into the installation U disk, unzip the EFI file and put it in the EFI partition, or you can choose a fat32 format U disk to store the EFI file separately Note: EFI is an unzipped folder, not a zip or ISO suffix file.
       
      BIOS settings From RehabMan
      To start, set BIOS to defaults.
      Then insure:
      UEFI boot is enabled (hybrid/with CSM for best result) secure boot is disabled disable fast boot IGPU graphics memory set to 64mb, if available disable the serial port via BIOS option, if available disable "LAN/WLAN switching", if available disable "Extended Idle Power States" if you find it under "Power Management Options" disable "Wake on LAN" and "Wake on USB" disable Firewire/IEEE 1394, if your laptop has it for Skylake and KabyLake laptop, enable "Launch Hotkeys without Fn keypress" Note: If you have a laptop with switchable graphics, leave it enabled. You can still use it on Windows, although the discrete card will be disabled when running OS X by the ACPI patches provided here. If you want to also disable it in Windows (via BIOS option), make sure you read about the DGPU option in your model specific SSDT (source is in SSDT-HACK.dsl), as in the scenario where the DGPU is disabled by BIOS, DGPU should be set to zero.
       
      Install:
      Please modify according to the above BIOS settings: Press F9 after booting, select the boot efi to file option, which is generally the last item. Enter your boot USB disk to find the location of cloverx64.efi, select cloverx64.efi, press Enter, and enter the clover boot interface. Select the location of the install entry and press Enter. Enter the macOS interface, use the disk tool to format the partition you need to install to hfs + or apfs format, do not choose the encryption option, this will make your efforts in vain. Note: The disk must be in gpt format, and the remaining EFI space is greater than 200M, 300mb + is recommended. If it is not, please try to modify it in WindowsPE environment. This may cause you to lose the Windows system boot and disk data. Please prepare for backup.
      After formatting the partition successfully, close the disk tool and select install, you will find the partition you installed, and follow the interface prompts. When the installation reaches a certain progress, it will restart. When restarting, select F9, enter from the boot U disk, select the disk partition where you installed macOS (no longer the U disk installation), the installation will continue, and it may restart 2 ~ 3 times Every time, you need F9 to select the boot. After entering the installation interface, except for the first installation, select the U disk, and then select the disk installation partition. Eventually you will enter the settings interface. After following the interface prompts, you will enter the macOS system interface. Remember the system password and turn off the Find my mac option.  
      Post install:
       
      After the installation is complete, you need to hang the EFI partition of the disk, copy the EFI file of the U disk to the EFI partition of the disk, so that you can directly use the disk to boot, otherwise you need to select the U disk to boot each time. The mount tool can choose cloverconfigurator. If after copying the EFI file to the disk, the computer cannot recognize your clover boot, you can use the custom boot option of bios: set the custom boot path to \efi\clover\cloverx64.efi, and set it as the first boot, Use bootice or easyUEFI to increase the clover boot option under Windows and set it as the first boot. If you do not have a wireless network card available temporarily, you can use the USB binding function of your Android phone to share the network. This may require the HoRndis driver. It is not recommended to use a US wireless network card. If you need Windows or Linux, you can install it normally. Be careful not to let Windows overwrite your boot files.  
      For other uses of macOS and brew, please pay attention to forums and other communities. Hackintosh is just the beginning.
       
      Finally, I would like to thank rehabman, vit9696 and others who contributed to Hackintosh. I also thank Cwen for his efforts to modify files and hardware tests. I hope that Hackintosh will be eternal.
       
      Please comply with the laws and regulations of your country or region. My description may not be clear or professional, but I think it is necessary. I think the existence of Hackintosh is everyone's technical hobby and experience macOS, not as a substitute for macOS cheap hardware.

      Can Someone make a guide to install macOS Mojave on the Surface Pro 1?
    • By grisno
      Hi people,
       
      This is a preliminary installer to activate the sound card IDT 92HD87B2/4 (111D:76D9) in MacOS. This new version of the installer does not contain AppleHDA patched Kext. To work properly, it must be installed over vanilla AppleHDA Kext.
       
      I want to thank the whole community for their efforts and content provided, because without these it would not be possible to create this installer.
       
      I would appreciate comments and suggestions!!
