Ok. First remove device bge in your kernel config. For example create a config file with: >>> BEGIN include GENERIC ident MYKERNEL (or what you like) nodevice bge <<< END After rebuilding and installing your kernel, you can do something like that: pciconf -w pci0:28:2 0xd8 0x04110008 pciconf -w -h pci0:28:2 0x58 0x0000 pciconf -w pci0:28:2 0x24 0x0001fff1 pciconf -w pci0:28:2 0x20 0xc830c830 pciconf -w -h pci0:28:2 0x04 0x0007 After that, you should be able to kldload if_bge and report back if this work. In that case I will modify the DSDT so that you won't to worry about all of those pciconf stuff. Good night! -- Bruno Ducrot -- Which is worse: ignorance or apathy? -- Don't know. Don't care.
