Bootloader: OC 0.7.5

Motherboard: ASRock B560m-itx/ac

CPU: Intel i5-10600k

RAM: 2 x 16GB Corsair Vengenance

WIFI: Fenvi T919

Followed the Dortania guide for Comet Lake as well as the USBToolbox guide for creating a USB Map in Windows 10.

Was previously getting stuck at a prohibited/scrambled screen before making a USB map. Now it's hitting a black screen during a lot of text activity on-screen and then the monitor just loses input.

Hey!

 

That actually got it booting! Thanks so much!

 

I don't recognise a lot of those SSDT files from the Dortania guides. Will I need all of them going forward, or should I test removing each one?

 

I see from "diff" that the 2nd config.plist removed PlatformInfo and added "-igfxvesa" to my boot string. Does this mean that my hack can't support Intel graphics acceleration?

 

Thanks so much for your time. Sorry about all the questions :)

Okay, so basically, it seems like if I enter my correct device-id (or leave it blank) under "PciRoot(0x0)/Pci(0x2,0x0)", then I get a blank screen.

 

If I enter the wrong device-id, then it boots, but with no acceleration (9MB VRAM).

 

I'm connecting via HDMI, if it helps.

Test this patch
