boards physically pull the machine down off their own onboard timers and
will reboot from almost anything.
-A second temperature monitoring interface is available on the WDT501P cards
+A second temperature monitoring interface is available on the WDT501P cards.
This provides /dev/temperature. This is the machine internal temperature in
degrees Fahrenheit. Each read returns a single byte giving the temperature.
The third interface logs kernel messages on additional alert events.
-The wdt card cannot be safely probed for. Instead you need to pass
-wdt=ioaddr,irq as a boot parameter - eg "wdt=0x240,11".
+The ICS ISA-bus wdt card cannot be safely probed for. Instead you need to
+pass IO address and IRQ boot parameters. E.g.:
+ wdt.io=0x240 wdt.irq=11
+
+Other "wdt" driver parameters are:
+ heartbeat Watchdog heartbeat in seconds (default 60)
+ nowayout Watchdog cannot be stopped once started (kernel
+ build parameter)
+ tachometer WDT501-P Fan Tachometer support (0=disable, default=0)
+ type WDT501-P Card type (500 or 501, default=500)
