EDIT2: I learned a lot in a short period of time and realize now that my questions below are naive (leaving them here so others don't feel so dumb about their questions). I ended up getting lucky in that I accidentally injected a bogus AAPL,ig-platform-id which prevented acceleration from loading and allowed the Catalina installer to boot to the install screen. After installing Catalina, I enabled sharing and was able to "remote" into my Catalina desktop until I found the correct combination of ig-platform-id and port types to produce a fully working system. My config.plist is attached and my system specs are below. The following were required for me to establish a working HackMini8,1:
EDIT: If not possible to capture the "-gfxdump" when booting with a USB stick, can I capture the equivalent of "-gfxdump" in Windows 10?
Is it possible to capture a -igfxdump by booting with a USB stick? I tried but didn't find the dump file on the USB stick. Details below...
I am trying to install Catalina 10.15.4 on an HP EliteDesk 800 G4 (I7-8700T, UHD630, 3 x DP Ports, SMBIOS MacModel MacMini 8,1). All attempts boot to a black screen (screen goes black after progress bar and before login prompt). I suspect that I need to inject display device properties. If I understand Hackintool / Framebuffer Patching correctly, I need to capture a framebuffer dump with Lilu/WhateverGreen/-igfxdump and use Hackintool to create the Framebuffer patch from the imported dump.
If I can't boot to a viewable display, how do I use Hackintool to create my Clover config.plist Framebuffer patch? I created a bootable USB Catalina installer (Clover UEFI r5115) with bootarg -igfxdump but didn't find the framebuffer dump on the USB.
Thank you for any help.

- AppleGraphicsDisplayPolicy patch: needed to permit multi-monitor on a MacMini8,1
