Abstract

In one or more embodiments, one or more systems, methods, and/or processes may detect commencement signals from respective backplanes. For each backplane of the backplanes, the one or more systems, methods, and/or processes may further configure a multiplexer to select a coupling associated with the backplane; may further provide, via a serial interface and the multiplexer, first information to the backplane; may further receive, via the serial interface, second information from the backplane; may further store the second information from the backplane; may further provide at least a portion of the second information to at least one of information handling system firmware, an operating system, and a boot management controller; and may further boot the operating system with the at least the portion of the second information associated with at least one of the backplanes.

Dependent claims

An information handling system, comprising:

at least one processor;
a device coupled to the processor;
and
a memory medium coupled to the at least one processor;
wherein the device includes a first multiplexer and a serial interface coupled to the first multiplexer;
wherein the device is configured to:
detect a plurality of commencement signals from a respective plurality of backplanes;
in response to detecting the plurality of commencement signals:
for each backplane of the plurality of backplanes:
configure the first multiplexer to select a coupling associated with the backplane;
provide, via the serial interface and the first multiplexer, first information to the backplane;
receive, via the serial interface, second information from the backplane;
store the second information from the backplane;
and
provide at least a portion of the second information to at least one of information handling system firmware, an operating system, and a boot management controller;
and
wherein the memory medium stores instructions executable by the at least one processor, which when executed by the at least one processor, cause the information handling system to:
boot the operating system with the at least the portion of the second information associated with at least one of the plurality of backplanes.
