NAME
ichwd - Intel ICH watchdog timer driverSYNOPSIS
device ichwdDESCRIPTION
This driver provides access to the watchdog timer (WDT) present on all Intel ICH chipsets.The ICH WDT counts down in ticks of approximately 0.6 seconds; the exact value depends on hardware quality and environmental factors. Supported watchdog intervals range from 2 to 63 ticks.
Note that on some ICH-based systems, the WDT may be present but disabled, either in hardware or by the BIOS. The driver attempts to detect this condition and will refuse to attach if it believes the WDT is disabled.
