Hi guy,

Apple BCM 57xx:

it looks like it can't access the nvram. how can i stop it from trying to access it and skip that step?

bump to top

NIZGTR 09-05-2009 10:28 PM
theres two ways to fix it

1. is to patch the kext to not check for the nvram

2. is to patch the getAdapterInfo part.

other wise it fails to identify the adapter and unloads, ill need help to find the right parts to patch so if anyone got a idea please post

anybody got any ideas?
