[Help] Kernel Panic during boot of the installation USB (Catalina)

[alba2015]

Hello , i'm new in the forum and i need help for a kernel panic that appears when i boot from the installation USB, and i can't reach the installation UI. It appears after about 30 seconds, but i don't know how to understand it (the error should be a cpu error, it seems). The version of Mac OS is 10.15.4. I followed a guide in the forum to set my device-id and the section Devices>Properties in Clover Configurator. I've also patched Intel Framebuffer using WhateverGreen.
KEXTS: FakeSMC (with all the sensors by RehabMan), NullEthernet, Lilu, WhateverGreen. -->ALL UPDATED TO THE LATEST VERSION
DRIVERS UEFI: apfs.efi, ApfsDriverLoader.efi, AptioMemoryFix.efi, AudioDxe.efi, DataHubDxe.efi, FSInject.efi, HFSPlus.efi, NvmExpressDxe.efi, OsxFatBinaryDrv.efi, PartitionDxe.efi, SMCHelper.efi.

My computer is a Dell Workstation with i7 8700k and in the bios "Legacy Option ROMs" is enabled, even if i boot in UEFI mode. Serial Port is disabled and VT-d is enabled.

Thank you for your help.

you may need to set DVMT pre to at least 64MB in your BIOS

Thank you very much for your responce. I can't change DVMT pre because i can't find it in the Dell bios.

you need to update your hardware profile properly as well

Dell is a bit vague, and also your graphics section as well

 

[alba2015]

Ok. Can i write the exact name of the model?

yes, ie:
Motherboard: Dell OPTIPLEX 3010
Graphics: Intel HD620

just for an example

Perfectly. I have done.

then you will need to enable the min stolen patch as indicated here:

[Guide] Alternative to the minStolenSize patch with 32mb DVMT-prealloc

Overview A common problem with Broadwell/Skylake/KabyLake is relatively small DVMT-prealloc setting by PC OEMs. The Apple framebuffer kexts generally assume 64mb or larger, and most PC OEMs use only 32mb. And often, there is no way to change it easily due to limited BIOS, locked down BIOS...

Ok, thank you. I will follow the guide, and update you. Only a question: does the min stolen patch conflict with my settings in the config.plist? Because there are some patches in Device section related to the framebuffer.

did you use clover configurator to generate a config.plist for you? if so, it looks a bit messy, too much rubbish in there

you will need to trial and error adding that patch in there
