Have you seen who wrote it? That guide i wrote initially for threadripper CPU, AM5 is a bit different to do an example , in my new x870e now i disable the variable quirk without doing any skip 1 and it works perfectly as before In Am5 usually it is enough to skip only the second MMIO Area...

Where do you read this?

More important for both and for 9900x comunity is to give @Shaneee debug log using his modded opencore efi driver and therelease unmodded one to undestand well how to proceed in a better way

@unclesam If we modify some bios settings mmio value could be different and you have to calculTe their value again For this reason i use in initial installation steps for unskilled users to disable mmio using only devirtualize mmio and disable write variable booter quirks When system works as it...

-1

check Resize bar in your quirk if you have enabled in Bios set to 0 in your config.plist now is set to ARBAR -1 (it means disabled) Problem you have it is difficult to solve from distance, you should do some tries by yourself and investigate well USB Map could be a part to do better I cant say...

@unclesam you are seein your goal ;) i dont know which efi are you using by now and if you did a revovery installer or a full installer A recovery installer needs of a working etherne /wifi to download OS You have to add Lucy kext for your realtek ethernet and to hope it is compatible with your...

No with hackingtool I use it only to check if i did well I use a tool done by corpnewt you can find it on his github

@Katanoko1221 something similar

these acpi patches was created from CorpNewt (aka corpghost) on AMD OSX Discord you have to add in your config.plist in ACPI /Patch section and try again

check if you see ACPI errors in your verbose output

you have different controllers xh00 as my asus so i cant say from this picture I see an hub (internal) mapped as USB2 and maybe also others usb are mapped wrong i will search in bios option for reboot shutdown problem obviusly i would also try to map well your USB

this is a common problem for other and old platform, you could solve searching about it (fix shutdown) one problem is due on some bios setting , the other could be somethig to improve in your config.plist search on bios wake on lan or similar you should also do an USB mapping and check if it is...

@unclesam i cant see mmio area in your debug try this config and post only opencore log (you can also check inside with MMIO string search if you see something) 850 chipset is new for me and i think you are the first one to use it (in public) with hackintosh

also a video where the system hangs is useful in this initial steps ;)

i would disable from bios wifi and IGPU of your CPU also this EFI misses ethernet kext for your realtek..we will see if we do some steps forward

if you like try this one and see

you initial config is bad i suggest to read because your platforn needs to create a MMIO whitelist or to bypass it as i did to config.plist you find in that thread additional problem for your x870e Gigabyte could be the need to patch your dsdt THis would be more clear when your system will...

no need for now, you have to follow that thread nvram is latest of your problem before you have a booting EFI
