The internal Intel HD3000 (HD2000) graphics uses shared RAM of up to 480 (482)MB,
but both IORegistryExplorer and the kext rapports 512MB.
Is it possible to patch / modify the DSDT so the shared RAM can be set to 384MB or 480MB ??
Or even better the current allocated shared RAM value set in the BIOS ??
I believe the graphics distortions / fields with missing graphics are caused by the kexts are using the non-exsistent RAM area between the physical shared RAM and the 512MB the kext uses..
As there are no answer I deduct that it is either not possible to set the shared RAM value correctly in the DSDT,
or nobody knows how to do it ??
