good day! still in the learning process on this thingy. am using tohleox86 on compaq c571nr. the problem is, i tried chun-nans advise about the bmc4311. so, downloaded the iopcifamily.kext provided, extracted it and installed using kexthelper as mentioned by him. after installation its says "...cross fingers, reboot..." (sorry can't remember exaclty). anyways, i restarted my system then the gray apple loading screen it's just stuck there. what seems to be the case? any help would be appreciated. thanks in advance!
