Hi
@mgregrs! Today I have updated again to the 2002 BIOS version. After pressing the "Memory OK" button a couple of times (it always happens when I modify the BIOS), I have configured the BIOS. My BIOS configuration is exactly what KGP offers in the Mojave thread. Well, just start from Cover. Catalina finder appears. I no longer have a mouse. In Catalina, Mojave and High Sierra, the same thing happens in all three systems. I made some catches of Catalina with BIOS 2002 and with Bios 1503. I also captured an IOReg in 1503 and another one in 2002. I attached the EFI. It is the same EFI for all systems. When reinstalling the BIOS 1503, everything works again. I have a friend who has the same equipment as he did but with a 7900x. Otherwise, it is accurate and the same thing happens. In any BIOS higher than 1503, the audio and USB (except 3.1) stop working. I am sure it must be something of the EFI. But, although I have been with Hackintosh for a while, I do not have the knowledge of many of you. If someone could review these files and tell me the way I should go, it would be of great value. It is true that bios 1503 is slower than 2002, but I have no choice but to work with 1503, which is where everything works for me. Regards.
Hello
@WoodCabin 
First of all - Please go to BIOS -> Boot - and check if you have
"Above 4G Decoding" -> On 
I regret to don't mention about that for people who reflash BIOS on our ASUS Prime Deluxe (I)
and I have 2nd pack of new better RAM and always after BIOS flash I have to
turn On PC -> wait few seconds -> turn off and press, or directly press MemOK button,
then after few seconds everything boot correctly and works great
What I do now - every time I save my BIOS config on USB drive, so after reflash I don't waste time to reconfigure
everything again and again with the same details..
If you want... tomorrow I can share more details about my BIOS configuration, so you will be able to compare everything,
*** if something still don't work (after you check if your Above 4G Decoding is ON
)
*** Of course I will check your all shared files and try to find some different things/details ...
BTW: Every time I forger enable 4G Decoding in BIOS I lost my mouse or I have other/different problems,
so it can be main details which cause your problems with USB etc..
If 4G decoding doesn't make a good enough job - leave it "On",
let us know and then we will find the rest of things/details what you need to fix your problems
PS: I just finished installation of Catalina with your EFI (1st time tested today) (easy-peasy)
I mean, it boot easy, all ACPI present - OK - etc etc...
Tomorrow I will check more little details, but at this moment I'm surprised
how easy it was, and how great it works at this moment...
---------------------------------
Hi bro, would you share your final working efi with me please. I have the same mobo and would like to save the time configuring it myself and also im still beginner at this.
If you are welling to share, please tell me which wifi/blutooth you are using and at which slot you installed it.
I saw rj510 efi, is this an opencore or clover? and the patched ssdt, should i also include them in the ACPI section under ssdt table?
Would really appreciate some guidance here, yeah and which bios version you are currently using? is it the same recommended 1902 that rj510 using?
Hi
@BavarianDNA
I just installed Catalina with new EFI which I try to configure it for my config, at this moment it's not finished...
if you need something immediately WoodCabin config is almost the same and very good on the same time
for our boards and very similar hardware as OSX Wifi 4360CD, Vega64 etc..
I can understand if you are beginner...,we all were there...
... so definitely you should read few forum guides and especially KGP guide few times
and few pages from this thread to avoid some basic questions and believe me it will be useful in future.
- rj510 folder with ACPI patches and config.plist from (post 244 - OpenCore thread)
was for Clover (as he mentioned in his post, in 5th line, so definitely you should read more carefully
)
- You have to use only these ssdt files/patches which you need for your hardware,
basics .aml files for ours Asus MB and others like Vega64.aml for GPU, ARPT for WiFi/BT card etc etc
(as mentioned in KGP guide - it's detailed - even with photos etc etc... so it's easier to understand
)
- About "guidance" - a lot of people will be able to help you, but you have to do a basic job,
it means read and learn basics, so if you don't spend some time on learning basics, people which
spent hours/days and months on research and tests will not spend their time for you...
That's why it's worth to read KGP and others guides etc, then if you have few questions - [first] use search tool,
and if you don't find something - write a question "in related to" ... thread
- About BIOS - I use 2002 BIOS with my custom image - which I shared in post
#1300
Personally I recommend 2002, based on my tests and good better results than before .. in last few days, but as I said it's my personal opinion. PS: Remember to enable Above 4G decoding after BIOS flash
// edit...----------------
@WoodCabin after few minutes I have everything what I needed in ACPI,
- audio -> tested (100% OK)
- GPU -> few more points in Geekbench, and same result in Luxmark,
- CPU -> Slightly 1-2% better score in Geekbench for multi and 4-5% for single core score ...
Now, it's time to sleep and I will make few more tests tomorrow...
PS: For my ASUS Hyper M.2 X16 card I used only my SSDT,
no more replacement in Clover, tomorrow I will update more info in "related to" thread
Have a good day!
Today I have returned to the version of Bios 1503 and everything has returned to work as if by magic
