The new WDT driver, to be checked in RSN, includes all these functions. It uses the ICS WDT-501P and provides alarms and kernel ans/or user callbacks for Temperature, fan speed, high voltage and low voltage alarms, as well as a (8 bit) temperature reading. The callbacks are part of the High Availability Server functionality. ---------- Sincerely Yours, Simon Shapiro Shimon@Simon-Shapiro.ORG Voice: 503.799.2313 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
