The driver assumes that the BIOS has correctly probed for cable types. I believe this is because the board designer gets to choose which GPIO on the 686B they wire the cable detection to. You'll need to check the layout, and study that section of the 686B manual. -- Adrian Cox http://www.humboldt.co.uk/ ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
