1. An information handling system comprising:at least one processor;
a management controller communicatively coupled to the at least one processor and configured to provide out-of-band management of the information handling system;
a serial peripheral interface (SPI) read-only memory (ROM); and
at least one logic device configured to reset the SPI ROM in response to an indication that the SPI ROM is to be reset, wherein the resetting includes:
causing a file system associated with the SPI ROM to be dismounted;
causing the SPI ROM to be detached from a SPI controller of the SPI ROM;
disconnecting a power source from the SPI ROM;
in response to a passage of a particular amount of time, reconnecting the power source to the SPI ROM;
causing the SPI ROM to be re-attached to the SPI controller of the SPI ROM; and
causing the file system associated with the SPI ROM to be remounted.
