| 1 | Completion Code. Generic plus the following command-specific completion codes: 80h=Attempt to start un-initialized watchdog. It is recommended that a BMC implementation return this error completion code to indicate to software that a Set Watchdog Timer command has not been issued to initialize the timer since the last system power on, reset, or BMC reset. Note that since many systems may initialize the watchdog timer during BIOS operation, this condition may only be seen by software if a BMC gets re-initialized during system operation (as might be the case if a firmware update occurred, for example). |
