I'm just about to create a custom Thunderbolt DROM... Without a proper DROM, this is what we currently get:

Hi Jiffyslot, how did you work this out?
Okay, the procedure for the edit went fine, but the USB stick won't boot via F12. Every time I select it, the screen goes dark for a moment and goes back to the F12 boot-option page.[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580
@CaseySJ Ok, education time for me. So in the EFI we have a disabled SAT0>SATA and in the DSDT.aml I can search for SATA. The questions I have are: Do you pull your system DSDT via whatever method you like (Maciasl I assume) and do a find/replace? If not, did you enable the name change in the...www.tonymacx86.com

That's all !
- Just make required modifications of DROM
- Use a dummy CRC8 and CRC32
- After reboot, use hackintool (or terminal command) to see all of System log
- Search for "DROM" text
- If you find a log about DROM error ... It show false CRC8 and then indicates the right CRC8
- Reboot
- Do the same thing with CRC32
- Replay line 3 and 4 until you don't find anything about DROM
Port 7 patching data is : 02 C7 to be replaced by 02 87 (I probably made a mistake on post few days ago )Currently we have:
Does this need to be either:
- 02 C7 -- TBSwitch7
or:
- 02 B7
- 02 08
Hi @yellocab and Thanks !Hi
I'm really impressed by Casey, Elias and all of you who work hard to investigate about TBT. Thanks a lot.
Could we imagine to use fashTBT.exe to flash the Thunderbolt ROM?
I'm sending a custom DROM to you by private message. Please check if it works. Port 7 does not yet appear...Port 7 patching data is : 02 C7 to be replaced by 02 87 (I probably made a mistake on post few days ago )
and use fixed 9 bytes data from rMac as we previously found : On our case (iMac19,1) it's 01580001000D000100
