- mjg59 4y agoSome part of the boot stack expected to be able to make VBE calls to set the inital screen mode before loading actual drivers, which means hardware that wants to support Windows 7 needs to provide a CSM layer to support that even if it's otherwise booting via EFI (the CSM layer just rewrites VBE calls into EFI GOP calls, so the graphics card doesn't need to provide VBE itself)
