Yes that 's just I want to explore more with DMAC :

Maybe we have to change the Length ?

Yes, pretty easy. Took me less than 20 seconds to check.

Hello Folks! Been running BS Beta GP for a week now and been blessed. First installation was thin and had problems like spotlight could not find anything. Second installation removed GBTTR rev1.0 and installation was thicker this time and after everything has been smooth. I run Parallels with multiple VMs and haven't had any issues at all. With Catalina had some issues especially after long time without reboots. At the moment the TB3 hot plug is not working. If I will connect any hardware it will freeze the OS. If HW connected during boot they work well and can handle sleep/wake cycles okay.My (TTR/Slot4) blue chip is patched and port 7 is shown in IORegistry. Thank you Loloflasix and everyone who has contributed their assets.

I can no longer boot 10.14.6. The progress bar fills all the way and does not load the OS. Any suggestions?

Same here. Catalina not booting and bios is instable with the same settings used on 2002 version. Now flashback 3203 to 2002: best version for my hardware at this moment.

Totally agree with you (same problem with newer bios on Deluxe)

Make sure your config.plist has:
Misc/Security/SecureBootModel set to "Disabled"

Thanks, there's a new note (2 days ago!!!) about it in the Troubleshooting Page
