HD4000 5MB with eDP internal display

[wushuangrong]

Hello guys,

I am trying to install Mojavu on my an old laptop LaVie Z PC-LZ550LS, i followed the guide https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093 and got errors booting clover, Problem Report files are attached.

The bios does not have option to set DVMT-prealloc, not sure if this is a problem. The config.plist i chose was config_HD4000_1600x900.plist.

please help me!
Any comment is welcome!

Thanks!

I finally installed Mojavu on my laptop, just replace AptioMemoryFix-64.efi with OsxAptioFixDrv-64.efi, and set ig-platform-id to 0x01660008. But now i have a blurred block region which moves following mouse (see attached image). I have searched the forum and found others have similar problems, it seems the problem is the "DVMT-prealloc" thing, but i don't know how to fix this.

I have RP files attached as per Laptop Frequent Questions.

Can someone help me out?

Send your computer's configuration table

Send your computer's configuration table

The computer's configuration:

Laptop model: LaVie Z PC-LZ550LS
CPU: i5-3337U/UM77
Graphics: HD 4000 (1600 x 900）

It also appears under my name.

Actually after several successful boots with ig-platform-id , it now won't boot anymore, can only boot with an invild ig-platform-id 0x12345678.

Mine is a notebook, below is my configuration
CPU I5-3210M 2.5G
Motherboard HM77
Graphics card HD4000
Audio ALC269
After creating the boot disk, unpack the install_EFI.zip into EFI to install the system.
After the system is installed, install Clover, decompress EFI.zip, copy the files to EFI, and increase or decrease the content as appropriate.

Thanks, i tried, but not good, a lot of errors printed and clover gui does not show up.
What is your internal display connector type?

I just checked the Intel driver info app in windows, and found that my display is an eDP one, and i heard it's impossible to use an eDP with HD 4000 core display. Is that's true? Is there a framebuffer patch method to enable graphics acceleration?

I attached again problem reporting files using the gen_debug tool.

Thank you guys!
