Hi Brian,  Thanks for your help, does it make a difference that I'm using 9front? I don't even seem to have a /sys/lib/firmware directory, and I'm not sure I have a ether4330.c either.  I'm sure it's obvious, but I'm a newcomer to Plan 9 and I apologise in advance if I'm missing obvious things. Thanks Garry ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T42a55b55ffb81417-Mbf9496cfdbfc3fb8ad314f25 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
