Here is some more information when I try to do a modprobe of smc911x it fails. I just reflashed my board, anyone know where this is built or how to get it installed ? # modprobe smc911x FATAL: Module smc911x not found. -- Joel ________________________________ From: Joel Parker <joe...@ya...> To: General mailing list for gumstix users. <gum...@li...> Sent: Tue, January 18, 2011 4:55:02 PM Subject: Re: [Gumstix-users] Cannot find device "eth0" I did that but it is unable to find eth0 still.

Also, you may need to change eth0 to eth1, but not likely if your board is new. -J.J. On Tue, Jan 18, 2011 at 1:37 PM, Joel Parker <joe...@ya...> wrote: > I have it installed and running !!
