| 2 | Timer Use [7] - 1b = don’t log [6] 1b = don’t stop timer on Set Watchdog Timer command (new for IPMI v1.5) new parameters take effect immediately. If timer is already running, countdown value will get set to given value and countdown will continue from that point. If timer is already stopped, it will remain stopped. If the pre-timeout interrupt bit is set, it will get cleared. 0b = timer stops automatically when Set Watchdog Timer command is received [5:3] - reserved [2:0] - timer use (logged on expiration when “don’t log” bit = 0b) 000b = reserved 001b = BIOS FRB2 010b = BIOS/POST 011b = OS Load 100b = SMS/OS 101b = OEM 110b -111b = reserved |
| 3 | Timer Actions [7] - reserved [6:4] - pre-timeout interrupt (logged on expiration when “don’t log” bit = 0b) 000b = none 001b = SMI (optional) 010b = NMI / Diagnostic Interrupt (optional) 011b = Messaging Interrupt (this is the same interrupt as allocated to the messaging interface, if communications interrupts are supported for the system interface) 100b,111b = reserved [3] - reserved [2:0] - timeout action 000b = no action 001b = Hard Reset 010b = Power Down 011b = Power Cycle 100b,111b = reserved |
| 4 | Pre-timeout interval in seconds. ‘1’ based. |
| 5 | Timer Use Expiration flags clear (0b = leave alone, 1b = clear timer use expiration bit) [7] - reserved [6] - reserved [5] - OEM [4] - SMS/OS [3] - OS Load [2] - BIOS/POST [1] - BIOS FRB2 [0] - reserved |
| 6 | Initial countdown value, lsbyte (100 ms/count) |
| 7 | Initial countdown value, msbyte |
| 8 | Present countdown value, lsbyte. The initial countdown value and present countdown values should match immediately after the countdown is initialized via a Set Watchdog Timer command and after a Reset Watchdog Timer has been executed. Note that internal delays in the BMC may require software to delay up to 100ms before seeing the countdown value change and be reflected in the Get Watchdog Timer command. |
| 9 | Present countdown value, msbyte |
