Hello,

i followed OC guide to install Vanilla install BigSur. Managed to install and boot into OS but my video card and sound not working.

WIFI - not supported
Audio - not working atm
Video - no acceleration

Tried to change couple of things but still my video shows 14MB of Vram memory

Audio tried layouts 11, 12, 18, with no luck.

by enabling csm, that should sort out the issue as i have seen that issue before

you may need to work out how to unlock your bios

there is also a website called bios-mods that may offer some help
