Per the radeon man page *here <https://www.freebsd.org/cgi/man.cgi?query=3Dxorg.conf&sektion=3D5&apropos= =3D0&manpath=3DFreeBSD+11.0-RELEASE+and+Ports>. *However this option has been removed after 10.2. Under Linux the you set it in yaboot bootloader by using 'radeon.agpmode=3D-1'. I do not know if this will work in loader.conf *Option* *"BusType"* *"**string**"* Used to replace previous ForcePCIMode option. Should only be used when driver's bus detection is incorrect or you want to force an AGP card to PCI mode. You should NEVER force a PCI card to AGP bus. PCI -- PCI bus AGP -- AGP bus PCIE -- PCI Express bus (used only when DRI is enabled) The default is *auto* *detect.* On Sun, Mar 5, 2017 at 3:35 PM, Hiroo Ono (=E5=B0=8F=E9=87=8E=E5=AF=9B=E7= =94=9F) < hiroo.ono+freebsd@gmail.com> wrote: > Thank you.
