Internal Graphics - Arous Pro 390 'Couldn't Allocate Runtime Area'

Hi there,

Im trying to enable internal graphics on my Gigabyte Aorus Pro 390 for hardware acceleration. But every time I enable internal graphics I'm faced with a

'Couldn't Allocate Runtime Area error allocating 0x1195a pages at 0x0000000000005beb000' error'. Im using SMBios 18,3.

I have tried adding slide=0 to boot flags and using OsxAptioFix2Drv-free2000.efi but still no luck.

Anyone have any ideas?

Many thanks in advance.
