ABSTRACT:
A baseboard management controller (BMC) hosts a real-time clock and non-volatile RAM replacement that does not require a battery power supply. The BMC includes an I/O mapped interface responsive to I/O accesses to an address range associated with storage locations of a real-time clock circuit and storage locations holding configuration information. The BMC receives power when a processor coupled to the BMC is not powered. The I/O address range may include70hand71h. A network interface may communicate information between a network external to the BMC and the real-time clock and/or the storage locations holding the configuration information. The network external to the BMC may communicate clock synchronization and/or configuration information to the BMC.
