Hey MaLd0n,
maybe you can help me again. In the past you did make me a patched dsdt for clover. The dsdt works fine with clover. I want to chance to oc. Now I created a new Bootstick with your oc efi files for 300er chipset, chance serial etc for smbios and copy the clover dsdt in /oc/acpi. I can boot from the stick, but i run into acpi errors under oc. With clover, no problems with acpi. Did i need a other dsdt for oc? In the zip i did remove the applealc.kext, because the zip is to big!
Greetings
