In linux kernel since version 2.6.20 (release Date: 2007-02-04)
Hardware driver for the TCO timer built into the Intel 82801
I/O Controller Hub family. The TCO (Total Cost of Ownership)
timer is a watchdog timer that will reboot the machine after
its second expiration. The expiration time can be configured
with the "heartbeat" parameter.
On some motherboards the driver may fail to reset the chipset's
NO_REBOOT flag which prevents the watchdog from rebooting the
machine. If this is the case you will get a kernel message like
"failed to reset NO_REBOOT flag, reboot disabled by hardware".
To compile this driver as a module, choose M here: the
module will be called i8xx_tco.
Note: This driver will be removed in the near future. Please
use the Intel TCO Timer/Watchdog driver.
