Re: Problems to get 4.6RC running on my laptlop

Boot to the loader, then say

'help set tunables'

and follow the instructions for disabling the PCI BIOS.  You'll need to 
add this command to /boot/loader.rc or repeat it on every boot.

or that we are to stand by the president, right or wrong, is not
only unpatriotic and servile, but is morally treasonable to
