thank you for the reply. the problem turned out to be a buggy acpi impementation. when I turned that off the error dissappered. Thank you. A side note, I am still having trouble trying to get whs to activate. whith your bios mod i can see the hp slic table. i created a whs disc with the oem bios files however it still is asking to activate. I am sorry if this is the wrong thread i will move it if needed. Thank you.
