When I asked on the list if the Diamond cards were supported someone mentioned that the LED didn't work due to a bug in the driver. Obviously not a bug but a sensible design decision :-). I don't think I'll bother with the kernel option, I'll leave the LED connected to the HD (gonna need another LED though as I'm getting a 2nd HD soon, /usr will have 4.5GB all to itself :-) ) > -- > David Kelly N4HHE, dkelly@nospam.hiwaay.net > ===================================================================== > The human mind ordinarily operates at only ten percent of its > capacity -- the rest is overhead for the operating system. > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-questions" in the body of the message -- FreeBSD - The Power To Serve http://www.freebsd.org My Webpage http://www.users.globalnet.co.uk/~markov _______________________________________________________________ Mark Ovens, CNC Apps Engineer, Radan Computational Ltd.
