Watchdog Status (WDSTATUS) — R/W. The value written to this register will be sent in the Alert
On LAN message on the SMLINK interface. It can be used by the BIOS or system management
software to indicate more details on the boot progress. This register will be reset to the default of
00h based on RSMRST# (but not PCI reset).
