System Management
The PCH provides various functions to make a system easier to manage and to lower the Total Cost of Ownership (TCO) of the system. Features and functions can be augmented using external A/D converters and GPIOs, as well as an external micro controller.
The following features and functions are supported by the PCH:
- First timer timeout to generate SMI# after programmable time
- The first timer timeout causes an SMI#, allowing SMM-based recovery from OS lock up
- Second hard-coded timer timeout to generate reboot:
- This second timer is used only after the 1st timeout occurs
- The second timeout allows for automatic system reset and reboot if a HW error is detected
- Option to prevent reset the second timeout via HW strap
- Various Error detection (such as ECC Errors) indicated by host controller:
- Can generate SMI#, SCI, SERR, SMI, or TCO interrupt
