What is working:

Video tried with couple of games and the games run smoothly.
Sound - you need to install AppleALC.kext into /System/Library/Extensions for sound to work.
Sleep
Shutdown,
ALL usb ports

Problem to resolve:

Error allocating 0x11c01 pages – tried OsxAptioFixDrv-64.efi, OsxAptioFix2Drv-64.efi, OsxAptioFix3Drv-64.efi, OsxAptioFixDrv-free2000, AptioMemoryFix but still no luck. It just sometimes won’t boot. Happens 1-2 times from 10 reboots.

Please try the attached EFI from a USB flash drive.

I don't know what SSDT-SB-OC.aml is for. It looked like it's trying address power management which can be done in config.plist so I deleted it.

I don't know what shikigva=40 does. Not sure if it's needed. I left it in place.

It boots, without slide=0 argument. Will test more, thanks.

Btw, NVRAM should be working for you now.

 

[hitmanbg]

It worked before too. Thanks will post results here in couple of days of testing

If you had EmuVariableUefi, NVRAM was not working. It's also why you had problems booting with those Aptio fixes and kept getting the "Error allocating..." messages.

 

[hitmanbg]

Yes, you are right pastrychef
I think it works now (20+ reboots).

Thank you very much for your help.

/Cheers

Just unplugged and booted into Catalina without any problems with built-in GFX card.
