A LM78 by any chance? I've had a look at the specs for this device and it shouldn't be too hard to write a driver for it. The main variable is that motherboards will be wired differently, with different fan tachometer and temp sensors connected to different LM78 input channels. A "driver" as such would have to be little more than a way of accessing and sampling the channels, some user space daemon would need to be monitoring the values and deciding what to do (or setting thresholds for alarms and resets by the driver) etc based on a lm78d.conf file or something. There would be too much variation to try and fit it into kernel options and flags. All I need now is a source for fans with tach outputs in .au - I can see it now - "you want a fan with what???".. :-( Cheers, -Peter -- Peter Wemm <peter@netplex.com.au> Netplex Consulting To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
